Cuttlefish. Practical homeopathic medicine The most important representatives of the class of cephalopods and their practical significance

Class Cephalopoda

Cephalopods are the most highly organized molluscs. They are rightly called the "primates" of the sea among invertebrates for the perfection of their adaptations to life in the marine environment and the complexity of their behavior. These are mainly large predatory marine animals that are able to actively swim in the water column. These include squid, octopus, cuttlefish, nautilus (Fig. 234). Their body consists of a torso and head, and the leg is transformed into tentacles located on the head around the mouth, and a special motor funnel on the ventral side of the body (Fig. 234, A). Hence the name - cephalopods. It has been proved that part of the tentacles of cephalopods is formed due to the head appendages.

In most modern cephalopods, the shell is absent or rudimentary. Only the genus Nautilus (Nautilus) has a spirally twisted shell, divided into chambers (Fig. 235).

Only 650 species belong to modern cephalopods, and there are about 11 thousand fossil species. This is an ancient group of mollusks known from the Cambrian. Extinct species of cephalopods were predominantly testate and had an external or internal shell (Fig. 236).

Cephalopods are characterized by many progressive features of organization in connection with the active lifestyle of marine predators. At the same time, they retain some primitive features that testify to their ancient origin.

External structure. Features of the external structure of cephalopods are diverse due to the different lifestyles. Their sizes range from a few centimeters to 18 m in some squids. Nektonic cephalopods are usually torpedo-shaped (most squids), benthic cephalopods are bag-shaped (many octopuses), nektobenthic are flattened (cuttlefish). Planktonic species are small in size, have a gelatinous buoyant body. The body shape of planktonic cephalopods can be narrow or similar to jellyfish, and sometimes spherical (squid, octopus). Benthopelagic cephalopods have a shell divided into chambers.

The body of a cephalopod consists of a head and a body. The leg is modified into tentacles and a funnel. On the head is a mouth surrounded by tentacles, and large eyes. The tentacles are formed by the head appendages and the leg. These are food trapping organs. The primitive cephalopod - boat (Nautilus) has an indefinite number of tentacles (about 90); they are smooth, worm-like. In higher cephalopods, the tentacles are long, with powerful muscles and bear large suckers on the inner surface. The number of tentacles is 8-10. Cephalopods with 10 tentacles have two tentacles - trapping, longer, with suckers at widened ends,

and the remaining eight tentacles are shorter (squid, cuttlefish). Seabed octopuses have eight tentacles of the same length. They serve the octopus not only to capture food, but also to move along the bottom. In male octopuses, one tentacle is modified into a sexual (hectocotyl) and serves to transfer the reproductive products into the mantle cavity of the female.

Funnel - a derivative of the leg in cephalopods, serves for a "reactive" way of movement. Through the funnel, water is forcefully pushed out of the mantle cavity of the mollusk, and its body moves reactively in the opposite direction. At the boat, the funnel has not grown together on the ventral side and resembles the sole of the foot of crawling mollusks rolled into a tube. The proof that the tentacles and funnel of cephalopods are leg derivatives is their innervation from the pedal ganglia and the embryonic anlage of these organs on the ventral side of the embryo. But, as already noted, some of the tentacles of cephalopods are derivatives of the head appendages.

The mantle on the ventral side forms, as it were, a pocket - a mantle cavity that opens outwards with a transverse slit (Fig. 237). A funnel protrudes from this gap. On the inner surface of the mantle there are cartilaginous protrusions - cufflinks that fit tightly into the cartilaginous recesses on the body of the mollusk, and the mantle is, as it were, fastened to the body.

The mantle cavity and funnel together provide jet propulsion. When the muscles of the mantle relax, water enters through the gap into the mantle cavity, and when it contracts, the cavity closes with cufflinks and the water is pushed out through the funnel. The funnel is able to bend to the right, to the left and even back, which provides a different direction of movement. The role of the steering wheel is additionally performed by tentacles and fins - the skin folds of the body. Types of movement in cephalopods are diverse. Octopuses often move on tentacles and rarely swim. In cuttlefish, in addition to the funnel, a circular fin serves for movement. Some deep-sea umbrella-shaped octopuses have a membrane between the tentacles - umbrella and can move due to its contractions, like jellyfish.

The shell in modern cephalopods is rudimentary or absent. In ancient extinct cephalopods, the shell was well developed. Only one extant genus, Nautilus, has retained a developed shell. The shell of Nautilus in fossil forms also has significant morphological and functional features, in contrast to the shells of other mollusks. This is not only a protective device, but also a hydrostatic apparatus. The nautilus has a spirally twisted shell divided by partitions into chambers. The body of the mollusk is located only in the last chamber, which opens outwards with the mouth. The remaining chambers are filled with gas and chamber fluid, which ensures the buoyancy of the body of the mollusk. Through

holes in the partitions between the chambers of the shell passes the siphon - the posterior process of the body. Siphon cells are able to release gases. When surfacing, the mollusk emits gases, displacing the chamber fluid from the chambers; when lowering to the bottom, the mollusk fills the shell chambers with chamber fluid. The mover of the nautilus is a funnel, and the shell maintains its body in suspension in the water. Fossil nautilids had a shell similar to that of the modern nautilus. Completely extinct cephalopods - ammonites also had an external, spirally twisted shell with chambers, but their partitions between the chambers had a wavy structure, which increased the strength of the shell. That is why ammonites could reach very large sizes, up to 2 m in diameter. In another group of extinct cephalopods, the belemnites (Belemnoidea), the shell was internal, overgrown with skin. Belemnites in appearance resembled shellless squids, but in their body there was a conical shell, divided into chambers. The top of the shell ended with a point - the rostrum. Rostrums of belemnite shells are often found in Cretaceous deposits and are called "devil's fingers". Some modern shellless cephalopods have rudiments of the inner shell. Thus, in cuttlefish, a calcareous plate is preserved on the back under the skin, which has a chamber structure on the cut (238, B). Only in spirula (Spirula) under the skin is a fully developed spirally twisted shell (Fig. 238, A), and in squid under the skin only a horny plate has survived from the shell. In females of modern cephalopods - argonauts (Argonauta), a brood chamber is developed, resembling a spiral shell in shape. But this is only a superficial resemblance. The brood chamber is distinguished by the epithelium of the tentacles, is very thin and is designed to protect the developing eggs.

covers. The skin is represented by a single layer of epithelium and a layer of connective tissue. The skin contains pigment cells called chromatophores. Cephalopods are characterized by the ability to quickly change color. This mechanism is controlled by the nervous system and is carried out by changing the shape

Rice. 238. Rudiments of a shell in cephalopods (according to Natalie and Dogel): A - spirula (Spirula); 1 - funnel, 2 - mantle cavity, 3 - anus, 4 - excretory opening, 5 - luminous organ, 6 - fin, 7 - shell, 8 - siphon; B - Sepia shell; 1 - septa, 2 - lateral margin, 3 - siphon fossa, 4 - rostrum, 5 - rudiment of siphon, 6 - posterior margin of proostracum

pigment cells. So, for example, cuttlefish, swimming over sandy ground, takes on a light color, and over rocky ground - dark. .At the same time, pigment cells with dark and light pigment in her skin alternately contract and expand. If you cut the optic nerves of a mollusk, then it loses its ability to change color. Due to the connective tissue of the skin, cartilage is formed: in cufflinks, the bases of the tentacles, around the brain.

Protective devices. Cephalopods, having lost the shell in the process of evolution, acquired other protective devices. Firstly, fast movement saves many of them from predators. In addition, they can defend themselves with tentacles and a "beak", which is a modified jaw. Large squids and octopuses can fight with large marine animals, such as sperm whales. Sedentary and small forms have a protective coloration and the ability to quickly change color. And finally, some cephalopods, such as cuttlefish, have an ink sac, the duct of which opens into the hindgut. Spraying the ink liquid into the water causes a kind of smoke screen that allows the mollusk to hide from predators to a safe place. Cuttlefish ink gland pigment is used to make high-quality artistic ink.

The internal structure of cephalopods

Digestive system cephalopods bear the features of specialization in feeding on animal food (Fig. 239). They feed mainly on fish, crabs and bivalves. They seize prey with tentacles and kill with jaws and poison. Despite their large size, cephalopods can only eat liquid food, as they have a very narrow esophagus that passes through the brain, enclosed in a cartilaginous capsule. Cephalopods have adaptations for grinding food. To gnaw their prey, they use hard horny jaws, similar to the beak of a parrot. In the pharynx, food is rubbed by the radula and abundantly moistened with saliva. The ducts of 1-2 pairs of salivary glands flow into the pharynx, which secrete enzymes that break down proteins and polysaccharides. The second posterior pair of salivary glands secretes poison. Liquid food from the pharynx through the narrow esophagus enters the endodermal stomach, where the ducts of the steam liver flow, which produces a variety of digestive enzymes. The hepatic ducts are lined with small additional glands, the totality of which is called the pancreas. The enzymes of this gland act on polysaccharides,

and hence this gland is functionally distinct from the mammalian pancreas. The stomach of cephalopods is usually with a blind saccular process, which increases its volume, which allows them to absorb a large portion of food. Like other predatory animals, they eat a lot and relatively rarely. The small midgut departs from the stomach, which then passes into the hind intestine, which opens with an anus into the mantle cavity. In many cephalopods, the duct of the ink gland flows into the hindgut, the secret of which has a protective value.

Nervous system cephalopods is the most highly developed among molluscs. The nerve ganglia form a large peripharyngeal cluster - the brain (Fig. 240), enclosed in a cartilaginous capsule. There are additional ganglia. The composition of the brain primarily includes: a pair of large cerebral ganglia that innervate the head, and a pair of visceral ganglia that send nerve cords to the internal organs. On the sides of the cerebral ganglia are additional large optic ganglia that innervate the eyes. Long nerves depart from the visceral ganglia to two stellate mantle ganglia, which develop in cephalopods in connection with the function of the mantle in their jet mode of movement. The composition of the brain of cephalopods includes, in addition to cerebral and visceral pedal ganglia, which are subdivided into paired ganglia of tentacles (brachial) and funnels (infudibular). The primitive nervous system, similar to the ladder system of lateral nerves and monoplacophorans, is preserved only in Nautilus. It is represented by nerve cords forming a peripharyngeal ring without ganglia and a pedal arch. Nerve cords are covered with nerve cells. This structure of the nervous system indicates the ancient origin of cephalopods from primitive shell mollusks.

sense organs cephalopods are well developed. Their eyes, which are of the greatest importance for orientation in space and hunting for prey, reach a particularly complex development. In Nautilus, the eyes have a simple structure in the form of a deep eye fossa (Fig. 241, A), while in the rest of the cephalopods, the eyes are complex - in the form of an eye bubble and resemble the structure of the eye in mammals. This is an interesting example of convergence between invertebrates and vertebrates. Figure 241, B shows the eye of a cuttlefish. From above, the eyeball is covered with the cornea, in which there is an opening into the anterior chamber of the eye. The connection of the anterior cavity of the eye with the external environment protects the eyes of cephalopods from the action of high pressure at great depths. The iris forms an opening - the pupil. Light through the pupil enters the spherical lens formed by the epithelial body - the upper shell of the eye bubble. The accommodation of the eye in cephalopods is different,

than in mammals: not by changing the curvature of the lens, but by approaching or moving away from the retina (similar to focusing a camera). Special ciliary muscles approach the lens, setting it in motion. The cavity of the eyeball is filled with a vitreous body, which has a light-refracting function. The bottom of the eye is lined with visual - retinal and pigment - cells. This is the retina of the eye. A short optic nerve departs from it to the optic ganglion. The eyes, together with the optic ganglia, are surrounded by a cartilaginous capsule. Deep-sea cephalopods have luminous organs on their bodies, built according to the type of eyes.

Organs of balance- Statocysts are located in the cartilaginous capsule of the brain. The organs of smell are represented by olfactory pits under the eyes or osphradia typical of mollusks at the base of the gills - in nautilus. The organs of taste are concentrated on the inner side of the ends of the tentacles. Octopuses, for example, use their tentacles to distinguish between edible and inedible objects. On the skin of cephalopods, there are many tactile and light-sensitive cells. In search of prey, they are guided by a combination of visual, tactile and taste sensations.

Respiratory system represented by ctenidia. Most modern cephalopods have two, while the nautilus has four. They are located in the mantle cavity on the sides of the body. The flow of water in the mantle cavity, which ensures gas exchange, is determined by the rhythmic contraction of the muscles of the mantle and the function of the funnel through which water is pushed out. During the jet mode of movement, the flow of water in the mantle cavity accelerates, and the intensity of respiration increases.

Circulatory system cephalopods almost closed (Fig. 242). In connection with active movement, they have well-developed coelom and blood vessels and, accordingly, parenchymality is poorly expressed. Unlike other mollusks, they do not suffer from hypokenia - poor mobility. The speed of blood movement in them is ensured by the work of a well-developed heart, consisting of a ventricle and two (or four - in Nautilus) atria, as well as pulsating sections of blood vessels. The heart is surrounded by a large pericardial cavity

Rice. 242. Circulatory system of cephalopods (from Abrikosov): 1 - heart, 2 - aorta, 3, 4 - veins, 5 - branchial vessels, 6 - branchial hearts, 7, 8 - portal system of the kidneys, 9 - branchial veins

which performs many functions of the whole. From the ventricle of the heart depart the head aorta - forward and splanchnic aorta - back. The head aorta branches into arteries that supply blood to the head and tentacles. Vessels depart from the splanchnic aorta to the internal organs. Blood from the head and internal organs is collected in the vena cava, located longitudinally in the lower part of the body. The vena cava subdivides into two (or four in Nautilus) afferent gill vessels, which form contracting extensions - gill "hearts" that promote gill blood circulation. The afferent gill vessels lie close to the kidneys, forming small blind protrusions into the tissue of the kidneys, which contributes to the release of venous blood from metabolic products. In the gill capillaries, blood is oxidized, which then enters the efferent gill vessels, which flow into the atria. Partially, blood from the capillaries of veins and arteries flows into small gaps, and therefore the circulatory system of cephalopods should be considered almost closed. The blood of cephalopods contains a respiratory pigment - hemocyanin, which includes copper, therefore, when oxidized, the blood turns blue.

excretory system represented by two or four (in Nautilus) kidneys. With their inner ends they open into the pericardial sac (pericardium), and with their outer ends into the mantle cavity. Excretion products enter the kidneys from the gill veins and from the extensive pericardial cavity. Additionally, the excretory function is performed by the pericardial glands formed by the wall of the pericardium.

Reproductive system, reproduction and development. Cephalopods are dioecious animals. In some species, sexual dimorphism is well expressed, for example, in the argonaut (Argonauta). The female argonaut is larger than the male (Fig. 243) and during the breeding season she secretes a thin-walled parchment-like brood chamber around the body with the help of special glands on the tentacles for carrying eggs, similar to a spiral shell. The male argonaut is several times smaller than the female and has a special elongated sexual tentacle, which is filled during the breeding season with sexual products.

Gonads and genital ducts unpaired. An exception is the nautilus, which has preserved paired ducts extending from the unpaired gonad. In males, the vas deferens passes into the spermatophore bag, where the spermatozoa stick together into special packages - spermatophores. In cuttlefish, the spermatophore is shaped like a checker; its cavity is filled with spermatozoa, and the outlet is closed with a complex plug. During the breeding season, the male cuttlefish, with the help of a sexual tentacle with a spoon-shaped end, transfers the spermatophore into the mantle cavity of the female.

Rice. 243. Mollusk Argonaut (Argonauta): A - female, B - male; 1 - funnel, 2 - eye, 3 - shell, 4 - hectocotyl, 5 - funnel, 6 - eye (according to Dogel)

Cephalopods usually lay their eggs at the bottom. In some species, care for offspring is observed. So, the female argonaut bears eggs in the brood chamber, and the octopuses guard the clutch of eggs, which are placed in shelters made of stones or in caves. Development is direct, without metamorphosis. The eggs hatch into small, fully formed cephalopods.

Modern cephalopods belong to two subclasses: the subclass Nautilida (Nautiloidea) and the subclass Coleoidea (Coleoidea). Extinct subclasses include: subclass Ammonites (Ammonoidea), subclass Bactrites (Bactritoidea) and subclass Belemnites (Belemnoidea).

Subclass Nautilida (Nautiloidea)

Modern nautilids include one order Nautilida. It is represented by only one genus Nautilus, to which only a few species belong. The distribution area of ​​Nautilus is limited to the tropical regions of the Indian and Pacific Oceans. Fossil nautilids number over 2,500 species. This is an ancient group of cephalopods known from the Cambrian.

Nautilids have many primitive features: the presence of an external multi-chambered shell, an unfused funnel, numerous tentacles without suckers, and manifestation of metamerism (four ctenidia, four kidneys, four atria). The similarity of nautilids with lower shell molluscs is manifested in the structure of the nervous system from cords without isolated ganglia, as well as in the structure of coelomoducts.

Nautilus is a benthopelagic cephalopod. It floats in the water column in a "reactive" way, pushing the water out of the funnel. The multi-chamber shell provides buoyancy of its body and lowering to the bottom. Nautilus has long been an object of fishing because of the beautiful mother-of-pearl shell. Nautilus shells have been used to make many fine jewelry pieces.

Subclass Coleoidea (Coleoidea)

Coleoidea is Latin for "hard". These are hard-skinned molluscs without a shell. Coleoidea is a thriving group of modern cephalopods, includes four orders, which include about 650 species.

Common features of the subclass are: lack of a developed shell, fused funnel, tentacles with suckers.

Unlike nautilids, they have only two ctenidia, two kidneys, and two atria. Coleoidea have a highly developed nervous system and sensory organs. The following three orders are characterized by the largest number of species.

Squad Cuttlefish (Sepiida). The most characteristic representatives of the order are cuttlefish (Sepia) and spirula (Spirula) with rudiments of the inner shell. They have 10 tentacles, two of which are agility. These are nektobenthic animals, they stay at the bottom and are able to actively swim.

Order Squid (Teuthida). This includes many commercial squids: Todarodes, Loligo, etc. Squids sometimes retain a rudiment

shells in the form of a horny plate under the skin on the back. They have 10 tentacles, like the previous unit. These are mainly nektonic animals that actively swim in the water column and have a torpedo-shaped body (Fig. 244).

Order Octopus (Octopoda). This is an evolutionarily advanced group of cephalopods without traces of a shell. They have eight tentacles. Sexual dimorphism is pronounced. Males develop a sexual tentacle - hectocotylus. This includes a variety of octopuses (Fig. 245). Most octopuses lead a benthic lifestyle. But among them there are nektonic and even planktonic forms. The Octopoda order includes the genus Argonauta - an argonaut, in which the female allocates a special brood chamber.

The practical importance of cephalopods

Cephalopods are food animals. The meat of cuttlefish, squid and octopus is used for food. The world catch of cephalopods currently reaches more than 1600 thousand tons. in year. Cuttlefish and some octopuses are also harvested for ink liquid, which is used to make natural ink and top quality inks.

Paleontology and phylogeny of cephalopods

The most ancient group of cephalopods is considered to be nautilids, whose fossil shells are already known from Cambrian deposits. Primitive nautilids had a low conical shell with only a few chambers and a wide siphon. Cephalopods are thought to have evolved from ancient, creeping shellfish with simple conical shells and flat soles like some fossil monoplacophorans. Apparently, a significant aromorphosis in the emergence of cephalopods consisted in the appearance of the first partitions and chambers in the shell, which marked the beginning of the development of their hydrostatic apparatus and determined the possibility of floating up, breaking away from the bottom. Apparently, the formation of a funnel and tentacles occurred in parallel. The shells of the ancient nautilids were varied in shape: long conical and flat spirally twisted with a different number of chambers. Among them there were also giants up to 4-5 m (Endoceras), which led a benthic lifestyle. Nautilids have undergone several periods of prosperity and extinction in the process of historical development and have survived to the present day, although they are now represented by only one genus of Nautilus.

In the Devonian, in parallel with nautilids, a special group of cephalopods begins to occur - bactrites (Bactritoidea), smaller in size and less specialized than nautilids. It is assumed that this group of cephalopods descended from a common yet unknown ancestors with nautilids. Bactrites turned out to be an evolutionarily promising group. They gave rise to two branches of cephalopod development: ammonites and belemnites.

A subclass of ammonites (Ammonoidea) appeared in the Devonian and died out at the end of the Cretaceous. During their heyday, ammonites successfully competed with nautilids, whose numbers at that time were noticeably declining. It is difficult for us to judge the advantages of the internal organization of ammonites only from fossil shells. But the ammonite shell was more perfect,

Rice. 246. Fossil cephalopods: A - ammonite, B - belemnite

than nautilids: lighter and stronger. The partitions between the chambers in ammonites were not smooth, but wavy, and the lines of the partitions on the shell were zigzag, which increased the strength of the shell. Ammonite shells were spirally twisted. More often, whorls of ammonite shell spirals were located in the same plane, and less often they had the form of a turbospiral (Fig. 246, A). According to some imprints of the body of ammonite fossils, it can be assumed that they had up to 10 tentacles, perhaps there were two ctenidia, beak-shaped jaws, and an ink bag. This indicates that the ammonites apparently experienced oligomerization of metameric organs. According to paleontological data, ammonites were ecologically more diverse than nautilids, and included nektonic, benthic, and planktonic forms. Most ammonites were small, but there were also giants with a shell diameter of up to 2 m. Ammonites were one of the most numerous marine animals in the Mesozoic, and their fossil shells serve as guiding forms in geology for determining the age of layers.

Another branch of cephalopod evolution, hypothetically derived from bactrites, was represented by a subclass of belemnites (Belemnoidea). Belemnites appeared in the Triassic, flourished in the Cretaceous and died out at the beginning of the Cenozoic era. In their external appearance, they are already closer to the modern subclass Coleoidea. In body shape, they resemble modern squids (Fig. 246, B). However, belemnites differed significantly from them in the presence of a heavy shell, which was overgrown with a mantle. The shell of belemnites was conical, multi-chambered, covered with skin. Remains of shells and especially their terminal finger-like rostrums, which are figuratively called "devil's fingers", have been preserved in geological deposits. Belemnites were often very large: their length reached several meters. The extinction of ammonites and belemnites was probably due to increased competition with bony fish. And now, in the Cenozoic, a new group of cephalopods enters the arena of life - coleoids (subclass Coleoidea), devoid of shells, with fast jet propulsion, with a sophisticated nervous system and sensory organs. It was they who became the "primates" of the sea and could compete on equal terms as predators with fish. This group of cephalopods appeared

in the Cretaceous, but reached its highest peak in the Cenozoic era. There is reason to believe that the Coleoidea have common origins with the Belemnites.

Ecological radiation of cephalopods. The ecological radiation of cephalopods is shown in Figure 247. From primitive testate benthopelagic forms capable of surfacing thanks to the hydrostatic apparatus, several paths of ecological specialization have been determined. The most ancient ecological directions were associated with the radiation of nautilids and ammonites, which swam at different depths and formed specialized shell forms of benthopelagic cephalopods. From benthopelagic forms, there is a transition to bentonekton (such as belemnites). Their shell becomes internal, and its function of the swimming apparatus weakens. Instead, they develop the main mover - a funnel. Later they gave rise to shellless forms. The latter undergo intense ecological radiation, having formed nektobenthic, nektonic, benthic, and planktonic forms.

The main representatives of the nekton are squids, but there are also fast-swimming octopuses and cuttlefish with a narrow torpedo-shaped body. The composition of the nektobenthos mainly includes cuttlefish, often swimming

or lying on the bottom, to bentonekton - octopuses that crawl along the bottom more than swim. Plankton include umbellate, or gelatinous, octopuses, rod-shaped squids.

External morphology of sepia; mantle cavity and mantle complex of organs; organs of the visceral (visceral) sac.

Work 1. External sepia morphology(fig.215). Two parts of the body are easily distinguished - the head and the trunk, separated from each other by the cervical interception. The area of ​​the body represented by the head can be called anterior, but it is more correct to consider it oral; it corresponds to the ventral side of the body of other molluscs; the opposite, aboral end corresponds to the dorsal side, but is usually referred to as the posterior. Bilateral symmetry is well expressed.

Rice. 215. Appearance of a sepia cuttlefish from the dorsal side:
1 - left trapping hand (the right hand is drawn into the tentacle bag); 2 - head: 3 - front dorsal protrusion of the mantle; 4,- torso; 5 - fin; 6 - leading edge of mangins; 7 - eye; 8 - the hand of the fourth pair; 9 - 10 - hands of the third and second pair; 11 - first pair of hands

The quadrangular head bears five tentacles, called arms, arranged in a crown around the mouth opening. Of these, four pairs are relatively short, muscular outgrowths; on the side facing the oral opening, they are provided along the entire length with numerous disc-shaped suckers. With their help, the animal is firmly fixed. The first pair are the tentacles located on the dorsal side, the fourth - on the ventral side. The fifth pair of tentacles are trapping hands; they are considerably longer, bear suckers only at the distal widened end, and may be retracted into special sacs at their base. With the help of these hands prey is captured. The bases of the arms surround an oval-shaped platform, in the center of which there is a mouth opening.

On the sides of the head lies a pair of large eyes of complex structure; behind them are small olfactory pits.

The back part of the body, the torso is oval in shape. dorsal

its side forms a small protrusion directed forward, covering the back of the head. On both sides and along the rear edge of the body, fins stretch - muscular skin folds. At the base of the head lies the inlet of the mantle cavity; it is closed by a roller located on the inside of the dorsal protrusion of the body (back button, or cufflink).

The shell is strongly reduced; the rest of it in the form of a large oval calcareous plate lies on the dorsal side of the body under the skin. It gives firmness to the entire dorsal surface of the body.


Rice. 216. Sepia female with open mantle cavity; ventral view:
1 - the first pair of hands; 2 - 3 - hands of the second and third pair; 4 - right trapping hand; 5 - the hand of the fourth pair; 6 - 7 - details of the structure of the trapping hand (6 - suckers, 7 - marginal fold of distal expansion); 8 - olfactory fossa; 9 - fossa of the abdominal closing apparatus; 10 - mantle ganglion, translucent through the integument; 11 - tubercle of the abdominal closing apparatus (cufflink); 12 - muscle - funnel retractor; 13 - mantle; 14 - right lobe of additional nidamental gland; 15 - nidamental gland: 16 - thickness of the mantle; 17 - fin; 18 - an ink sac visible under the integument of the visceral sac; 19 - its duct; 20 - opening of the left nidamental gland; 21 - middle lobe of the accessory nidamental gland; 22 - inner edge of gill axis; 23 - sexual opening; 24 - left renal orifice: 25 - left ctenidium (gill); 26 - anus at the end of the anal papilla: 27 - 29 - funnel ( 27 - back section 28 - anterior section 29 - front hole); 30 - mouth opening 31 - suction cups

Working process. 1. Familiarize yourself with the appearance of sepia; consider the most important features of external morphology: body parts, their shape and location; hands, eyes, olfactory pits and mouth opening on the head; fins and back cufflink. 2. Remove the sink and familiarize yourself with its appearance. To do this, cut the skin on the dorsal side of the body along the medial line with a scalpel.

Work 2. Mantle cavity and mantle complex of organs. The body of the sepia is surrounded by a mantle: on the dorsal side it is fused with the body of the mollusk, and on the abdominal side it forms a mantle cavity, in which the organs included in the mantle are located.

complex, and visceral sac (Fig. 216). On the ventral side, on the border between the head and the body, there is an entrance to the mantle cavity in the form of a narrow slit through which the cavity communicates with the external environment.


Rice. 217. Internal sac of a female after removal of integuments; ventral view:
1 - 3 - distal end of the digestive system 1 - anus, 2 - abdominal anal lobe, 3 - lateral anal lobe); 4 - right renal orifice; . 5 - ink bag duct; 6 - rectum; 7 -8 -gill ( 7 - gill petals, 8 - inner edge of the gill axis); 9 - opening of the right nidamental gland; 10 - gill heart; 11 - nidamental gland; 12 - abdominal renal sac; 13 - stomach; 14 - posterior small intestine 15 - ovary; 16 - ink bag: 17 - lateral abdominal vein; 18 - oviduct: 19 - blind sac of the stomach; 20 - pericardial gland; 21 - left lobe of the accessory nidamental gland; 22 - ovoid gland; 23 - genital papilla; 24 - female genital opening: 25 - left renal papilla; 26 -anal papilla

The center of the anterior half of the mantle cavity is occupied by an organ called the funnel because of its funnel-shaped shape. The tapered end of the vorogka faces forward and opens outwards with a hole. The second opening is at the posterior end, opening into the mantle cavity. There is a pair of crescent-shaped recesses on the posterior expanded section of the funnel on its sides. They correspond to a pair of cartilaginous thickenings on the inner surface of adjacent sections of the mantle (buttons, or cufflinks). The thickenings enter the recesses, fasten the mantle to the funnel and lock the mantle cavity. Thickenings and depressions together form the ventral closing apparatus of the mantle.

The funnel serves as a swimming organ. The muscles of the mantle, contracting, press the mantle to the body and forcefully push water out of the mantle cavity through the hole in the funnel. The body of the mollusk receives a push in the opposite direction, from front to back. Closing devices (dorsal and abdominal cufflinks) prevent water from escaping from the mantle cavity. Water comes out only through the funnel. Then the gap opens and water rushes into the mantle cavity. A special valve in the funnel closes the outlet of the funnel and prevents water from flowing back. This ensures the directed movement of water - from the mantle cavity through the funnel to the outside.

days, bipinnate formations (Fig. 217). Each of them is formed by a gill axis and two rows of folded petals. The opium side (where the axis is located) of the gill is attached to the mantle; opposite free ends of gill filaments facing forward. In the place of the pairwise connection of the gill filaments (along the axis), a longitudinal canal passes, which communicates with the mantle cavity by numerous holes. Rhythmic contractions of the muscles of the mantle, which ensure the movement of the animal with the help of the funnel, simultaneously cause the circulation of water, washing the gill filaments from all sides. Along the edges of each gill lobe are afferent and efferent blood vessels.

The anal opening is located medially behind the funnel, at the end of the long anal papilla (papilla) (see Fig. 216). The anus is covered by the lobes surrounding it. Close to the base of the anal papilla to the right and to the left of it lie the renal papillae, which open with the external openings of the kidneys. Asymmetrically, on the left between the gill and the renal opening lies the genital papilla with the genital opening.


Rice. 218. Digestive system of sepia: view from the ventral side:
1 - 4 - pharynx ( 1 - throat. 2 - common salivary duct 3 - salivary duct 4 - posterior salivary gland); 5 - esophagus; 6 - aorta; 7 - liver; 8 - pancreas; 9 - 10 - stomach (9 - proper stomach 10 - blind bag); 11 - small intestine; 12 - hepatic duct; 13 - rectum; 14 - ink bag duct; 15 - anus; 16 - transected head capsule: 17 -cavity of the statocyst capsule; 18 - severed nerve ring

Funnel, ctenidia and outlets of internal organs - anal, renal, genital - with the corresponding papillae make up the mantle complex of organs.

Working process. To study the mantle complex of organs. Ⅰ. Open the mantle cavity. Place the cuttlefish with the back side down. Cut the mantle on the ventral side along the median line, starting from the front edge. Take the edges of the incision to

sides and pin with pins to the bottom of the tub. 2. Consider the appearance and arrangement of the organs of the mantle complex in the sequence: funnel, abdominal cufflinks, ctenidium, anal, renal and genital openings with the corresponding papillae. 3. Cut out and examine in alcohol under a magnifying glass one ctenidium.

Work 3. Organs of the visceral (visceral) sac. The wall of the visceral sac delimits the mantle cavity from the dorsal side.


Rice. 219. Schematic representation of the respiratory, circulatory and excretory systems of sepia; view from the ventral side. The contours of the abdominal renal sacs are shown with a broken line:
1 - head aorta; 2 - right external renal opening; 3 - right renopericardial foramen; 4 - the space between the renal sacs through which the intestine passes; 5 - in- a heart (5 - ventricle. 6 - right atrium); 7-11 - respiratory organ 7 - ctenidium, 8 - gill vein 9 - gill petals, 10 - gill artery, 11 - gill heart); 12 - non-ricardial gland; 13 - venous appendages; 14 - 20 - sections of the circulatory system (14 - right lateral abdominal vein 15 - abdominal aorta 16 - posterior artery, 17 - ink sac vein 18 - anal artery 19 - left pudendal vein 20 - left vena cava); 21 - left renal sac; 22 - cephalic vein

Digestive system(Fig. 218). The mouth opening (see above) leads to a muscular pharynx. Inside the pharynx, two horny jaws, dorsal and ventral, are curved so that they resemble the beak of a parrot in shape. Strong muscles are attached to the jaws. The tongue protruding into the cavity of the pharynx is covered with a radula, or grater. It also opens the ducts of the salivary glands.

The esophagus departs from the pharynx - a long tube leading to a voluminous muscular stomach, divided into two sections: the stomach itself and the blind sac. From the front of the stomach, near the confluence of the esophagus, the small intestine departs, followed by the rectum. The latter ends with an anus opening into the mantle cavity on the anal papilla.

On both sides of the esophagus are the right and left lobes of the digestive gland-liver. The hepatic duct from each lobe goes back and opens into the blind sac

stomach. The ducts are covered by the groin-shaped pancreas; the secret of the latter enters the gaps of the proto-seams.

At the back of the visceral sac is a voluminous ink sac (see Fig. 217) - a gland that secretes a liquid black like ink. A long duct extending from it goes forward and opens into the lumen of the rectum near the anus. In the glandular part of the sac, epithelial cells are filled with black pigment - melanin. From here, melanin enters the second section of the bag - a reservoir, from where it can be thrown out through the rectum.

excretory system(rice, 219). The kidneys in the form of large elongated sacs are located on the ventral side of the visceral sac on both sides of the rectum. (In females, they are covered on the ventral side by the nidamental glands; see Fig. 217.) Short ureters in the form of renal papillae are directed forward and open into the mantle cavity with renal openings. On the dorsal side, the dorsal unpaired renal sac connects both pouches.

The rencipericardial opening, which connects the kidney to the pericardial coelom, lies on the dorsal wall of each kidney, behind the base of the ureter.

Circulatory system(see fig. 219). The three-chambered heart, consisting of a ventricle and a pair of atria, lies in the pericardium. The saccular ventricle is shifted slightly to the right. The head aorta extending from its anterior end is directed forward, passes over the esophagus between the lobes of the liver and is connected with the head and tentacles. From the back of the ventricle, the abdominal (splanchnic) artery departs, supplying blood (r) to the intestines. The third artery, the genital artery, departs from the anterior side of the ventricle, goes around it and goes to the gonad.

On the sides of the ventricle lie the atria associated with it. They receive blood from the gill veins (efferent vessels) located above the axis in the gill; they collect blood oxidized in the capillaries of the gills.

In front of the visceral sac, next to the head aorta, lies the cephalic vein, which carries venous blood from the anterior part of the body. It divides into two vena cava, going to the ctenides. From the back of the body, venous blood is carried out by the abdominal vein. The venous cut enters the gills.

At the base of the gill behind the atrium lies the gill (or venous) heart - a rounded sac. With its contractions, the gill heart pushes venous blood coming from the vena cava into the gill artery (bringing vessel). Only oxidized blood enters the heart. The circulatory system is almost closed; arteries with the help of capillaries with their own walls are directly connected with the veins.

Nervous system . The sepia ganglia are very curly and closely spaced. They form a common ganglionic mass, divided into two sections - above and below the esophagus. A complex system of nerves departs from the ganglia to various parts of the body.

The sense organs are well developed - the eyes, the olfactory fossae, the tongue papilla (the organ of taste), the hands as organs of touch, and a pair of statocysts. The latter are enclosed within the cartilaginous head capsule and serve as balance organs.

reproductive system. In males and females, the reproductive system is represented by an unpaired gonad and a single genital duct that opens outwards with a genital opening located on the left half of the abdominal side.

Females also have nidamental glands located on the ventral side of the visceral sac. A pair of larger glands lies somewhat further back. In addition to them, in front there is an additional three-lobed nidamental gland, one middle lobe (see Fig. 216) and two lateral (see Fig. 217). The mucous secretion of the nidamental glands is secreted to the right and left of the midline of the body and forms the outer shells of the eggs.

Working process. 1. Get acquainted with the appearance of the internal organs and their location. Turn the cuttlefish with the ventral side to the bottom of the bath. The internal organs are covered by the bottom of the shell bag. Through its transparent integument one can see: a large dark brown liver in front and an visceral sac in the back. Through the wall of the latter shine through: gonad, ink sac, kidneys. 2. Expose the internal organs. Remove the bottom of the sink bag. Examine and then remove the large unpaired dorsal renal sac. Cut off the scalp on the dorsal side, expose the cartilaginous hungry capsule, dissect its dorsal wall along the midline, push the edges of the incision apart. 3. Dissect and examine the organs of the anterior part of the digestive system - the pharynx, esophagus, stomach with a blind sac. 4. Open the sac. Flip the sepia on the ventral side; up. Remove the covers of the visceral sac, being careful not to damage the ink sac (in case of failure, rinse the preparation thoroughly). 5. Familiarize yourself with the appearance and location of the ink sac, with its duct, and, in case of dissection of the female, with the nidamental glands - large to additional. 6. Consider the posterior part of the digestive system. Bring the scalpel handle under the back edge of the ink sac and separate it from the visceral sac. Consider the small and rectum, anal papilla with anus. 7. To study the circulatory system - the heart (ventricle and atria), gill hearts, posterior head aorta. Turn the cuttlefish back side up and look at the front

head aorta. 8. Turn the sepia again on the dorsal side and examine the organs of the female reproductive system - the gonad, the thin-walled sac in the back of the body, and the nidamental glands - towards the anterior end.

  • Type: Mollusca Linnaeus, 1758 = Mollusca, soft-bodied
  • Class: Cephalopoda Cuvier, 1797 = Cephalopoda
  • Order: Sepiida Zittel, 1895 = Cuttlefish
  • Species: Sepia apama = Giant Australian cuttlefish

    The giant Australian cuttlefish can reach 50 centimeters in length and is considered the largest cuttlefish in the world. Its weight can reach from 3 to 10 kilograms. There is sexual dimorphism in size - males always outnumber females in size.

    The Giant Australian Cuttlefish is an endemic Australian species. It lives exclusively in coastal waters in the south, southwest and southeast coasts of Australia, from the coast of Queensland to Shark Bay in Western Australia. And there is a giant Australian cuttlefish at depths of up to about 100 meters, but even more often prefers shallow water.

    The giant Australian cuttlefish has a body slightly flattened in the dorsal-abdominal direction, which is decorated with a wide leathery fold on the sides. Here, on the sides of the body, there are also fins - the main organ of their movement in the water. The head end of the urvkatica is adorned with 10 tentacles. Of these, 2 tentacles are grasping, they are the longest, although they can be completely retracted into special sac-like pits under the eyes. The remaining 8 tentacles are short, and all are located around the mouth, framing it. All tentacles are equipped with suction cups that are very necessary for the animal. There is a difference in the structure of the tentacles of cuttlefish of both sexes. So in a male, unlike females, the 4th tentacle serves to fertilize females.

    The respiratory organ of cuttlefish is the gills. On the dorsal side of the body under the mantle, there is a porous calcareous shell, which looks like a plate, which gives the animal a fixed body shape. The eyes are similar in structure and visual acuity to human eyes. Cuttlefish, if necessary, are able to change the shape of the lens. Their mouth, like that of other cephalopods, consists of a strong beak, which is shaped like the beak of birds, especially a parrot, there are also jaws and a tongue.

    Speaking about the features of the internal structure of cuttlefish, it remains unclear why nature endowed these creatures with 3 hearts. In this case, one is responsible for the blood supply to the nervous system, and the other two are responsible for the coordinated work of the gills. And the blood of cuttlefish is not red, but blue. The blue color of blood is caused by the presence of a special pigment called hemocyanin in it. Hemocyanin, like hemoglobin in vertebrates, is responsible for the transport of oxygen.

    The giant Australian cuttlefish is known for its unique ability to instantly change its color, which can depend both on the mood of the animal and the characteristics of the environment. The coloration of males changes greatly during the mating season. This becomes possible due to the presence of a special pigment in the cells of the body, which is responsible for their stretching or contraction, depending on the signals from the nervous system. During the mating season or during an attack on prey, their color acquires a metallic sheen and is covered with bright luminous dots.

    An interesting feature of this species is that during the mating season, males can sometimes pretend to be females in order to try to outwit a stronger rival and try to get closer to the female. If they succeed in this maneuver, they mate with her very quickly and retreat until the dominant male has figured out what's what ...

    Giant squids use their ink stores as a defense against predators. In case of danger, the squid releases an ink cloud either directly into the “face” of the enemy, after which, under its cover, they quickly hide away, or a little to the side. At the same time, the spot often takes on such a shape that it becomes a bit similar in shape to the cuttlefish itself, and this, albeit for a short time, distracts the attention of the predator from the cuttlefish's own person.

    The giant Australian cuttlefish is predominantly nocturnal. They spend most of their time hiding among kelp beds, rocky reefs, or simply burrowing into the seabed. Cuttlefish are homebodies, they spend almost all their active time on a small territory, not exceeding 500 m2. Therefore, they spend most of the food energy absorbed by them not on motor activity, but on their own growth.

    The giant cuttlefish is very curious and is not averse to even playing, which is often used by divers. Despite their relatively peaceful nature and cute appearance, cuttlefish are dexterous predators, extracting various small mollusks and crustaceans, fish, sea worms and even small cuttlefish for food. Cuttlefish go hunting at night, attacking prey from an ambush, grabbing it with two long tentacle arms.

    By their nature, cuttlefish are solitary, and only during the breeding season, which falls on June-August, they often gather in large groups. One such favorite place for marriage dates is False Bay, located in the northern part of Spencer Bay. At this time, it is simply teeming with giant cuttlefish, and at this time there are almost 1 individual per 1 m2. This is where the fun begins. The largest and strongest males begin to care for the females. They "put on" a bright wedding dress and begin to wave their long "arms" in front of their chosen one. At the same time, they drive away smaller and younger males. Then they are forced to go for a deceptive maneuver, changing their bright cavalier outfit to "ladies" and under the guise of "females" they try to make their way through the "vigilant guard" to the females. And if the dominant male is distracted for a few moments, the werewolf immediately quickly acquires his bright male color in front of the female and mates with her, transferring his spermatophores to her with the help of the 4th “hand”, and quickly swims away from trouble.

    After some time, females lay eggs under stones or in other hard-to-reach places, enclosed in a thick shell. After that, they die. And the cubs are born, depending on the temperature of the water, after 3-5 months, having a body length of about 2.5 centimeters. Outwardly, they are very similar to adults, and at this age they feed only on plankton.

    The meat of the giant cuttlefish is edible and is widely used in cooking as food. Cuttlefish ink is still used in painting today. Therefore, large-scale capture of this species for export is currently underway, because of which the giant cuttlefish is already at risk of declining numbers. Now the capture of the giant Australian cuttlefish in False Bay in Australia is prohibited.

    Sepia officinalis— Pharmacy cuttlefish

    belongs to the class of cephalopods.
    The drug is prepared from trituration of dried

    the liquid contents of the ink bag.

    CHARACTERISTIC
    The current use of sepia in

    medicine we owe to Hahnemann.

    Some of the ancient doctors (Dioscorides,

    Pliny and Marcellus, writes Teste) used either meat or eggs,

    or even just a bone of the skeleton of this animal with "leucorrhoea, gonorrhea, cystitis,

    sand in the urine, bladder spasms, baldness, freckles and

    certain types of eczema", which seems surprising in the light of the

    tests.

    Sepia is one of the remedies described in "Chronic Diseases"

    it has been tested by Goullon, von Gersdorff, Gross, Hartlaub and Wahle.

    Sepia is predominantly (but not exclusively) a feminine remedy.

    It affects the reproductive system of both men and women and a range of

    symptoms from other organs.

    Teste describes the type that Sepia is suitable for as follows:

    young people of both sexes, or rather, people of reproductive age

    (from puberty to the critical period), fragile physique,

    with clear, white or pink skin, light or red

    hair, with a nervous and lympho-nervous temperament, extremely

    excitable, anxious and emotional, especially subject to strong

    sexual arousal or exhausted by sexual excesses.

    Hering describes the following types:

    1) People with dark hair, rigid muscles and a soft, docile

    character.

    2) Women during pregnancy, childbirth and lactation.

    3) Children who catch cold easily when the weather changes.

    4) Scrofulous patients.

    5) Men prone to alcohol abuse and sexual excesses.

    6) Irritable women with a big belly, a yellow "saddle" on

    nose, leukophlegmatic constitution, and debility arising from

    the slightest tension.

    According to Bahr, these are: "Excitable, plethoric people, prone to

    congestions." Farrington adds that Sepia patients are quite sensitive

    to any impressions and that dark hair is by no means

    obligatory sign.

    He gives a fuller description: edematous, lethargic people (significantly

    less often - emaciated) with yellow or dirty yellow, as well as brown skin,

    covered with spots; with excessive sweating, especially in the genital area,

    armpits and on the back; hot flushes; headache for

    in the morning; they wake up with stiffness in the muscles and a feeling of fatigue;

    susceptible to diseases of the genital organs; in general, patients are weak and

    painful, with weak connective tissue, lethargic, they easily

    paresis occurs.

    Sepia affects the vital forces as much as it affects the tissues of the body.

    The upward spread of Sepia symptoms is one of its

    key symptoms.

    The patient experiences a feeling of constant pressure in the vagina,

    which forces her to cross her legs to avoid prolapse.

    The feeling of weakness and emptiness is one of the main characteristics of Sepia.

    There are some features of the mental state of Sepia,

    that need to be remembered.

    1) Anxiety: with flushes of heat to the face and head, fear of misfortune,

    real or fictional; stronger in the evening.

    2) Strong sadness and tears, fear of loneliness, fear of men, meetings with

    friends (combined with diseases of the uterus).

    3) Indifference, even to one's own family, work, the dearest and closest people.

    4) Greed and avarice.

    5) Lethargy.

    Sepia patients cry when asked to describe their symptoms.

    Patients are very sensitive and do not tolerate when they point out shortcomings.

    Another characteristic of Sepia is "frequent fainting",

    weakness after getting wet; due to extreme heat or cold; while driving

    in the crew; when kneeling in church.

    Lorbacher describes three important references to Sepia that are little known:

    1) pre-stroke state;

    2) whooping cough that lasts endlessly;

    3) congestive pleurisy.

    "Stiffness" is the hallmark of Sepia: stiffness in

    limbs worse after sleep; stiffness in the uterus.

    Sepia is indicated by open fontanelles in children.

    Aggravation from kneeling is a very characteristic sign.

    PSYCHE
    Sadness and depression with tears. Melancholy and gloominess.

    Anguish and restlessness, sometimes with flushes of heat, mostly in the evening.

    (during a walk in the open air) and sometimes in bed.

    Anxiety, restlessness. Fear of being alone.

    Increased nervousness, sensitivity to the slightest sound.

    Great anxiety about one's health and household chores.
