Little-known fish. The most terrible fish in the world caught by humans (22 photos)
The waters of the world's oceans are home to countless fish and other marine animals. Ordinary people have no idea about some of them. The study of marine fauna began relatively recently. This is due to the fact that previously there was no appropriate equipment for diving to great depths. The Frenchman Jacques Yves Cousteau made a huge contribution to in-depth research. It was he who discovered many marine inhabitants that are included in the TOP 10 most amazing fish.
Blobfish
The list of the 10 most amazing fish opens with the drop fish. It is found at a depth of 900-1200 m and is practically no different from its counterparts. But as soon as she gets on land, her gelatinous body swells, and sea creature transforms into an unusual creature with a large nose. The blob fish appeared in the film “Men in Black” in the episode of the third part with a Chinese restaurant.
In second place we placed the predatory Scorpionfish of Ambon, which has an extravagant appearance. Discovered in 1856, this deep-sea dweller has distinctive eyebrow-like projections above its eyes. Its ability to change color helps well in hunting: Scorpionfish waits for its prey, merging with the seabed.
Psychedelic Frogfish
Continues the list of 10 most amazing fish psychedelic frogfish, so named for its extravagant appearance and unusual coloring: bright orange with white stripes. It was opened only 8 years ago. The tail and fins of this sea dweller resemble the limbs of an amphibian. The frog fish looks at the world with bright blue eyes. Its unusually shaped fins allow it to push off from the bottom and move by jumping.
Semicossyphus reticulatus
Scientists know little about Asian sheephead wrasses. These fish are distinguished by the presence of large growths on the forehead and chin. Moreover, young animals do not have such features: bulges appear in adults. Perhaps these are signs of sexual dominance of males or females. There is a well-known story about a 25-year friendship between a similar fish named Yoriko and a Japanese diver.
Leafy Seadragon
When talking about the most amazing fish on the planet that live in the waters of the world's oceans, one cannot fail to mention the rag picker. This fish was discovered in 1865. The head and body of these representatives of the fauna are covered with processes very similar to algae. With their help, fish camouflage themselves during hunting and hide from enemies. They feed on shrimp, plankton and algae, swallowing food whole because they do not have teeth. They live in the southern part Indian Ocean.
Ocean Sunfish
The moon fish was discovered in 1758. Its body is shaped like a disk, flattened on the sides. The fins grow together, touching the tail. It was for this structure of the body of the deep-sea inhabitant that they dubbed it the moon. This species is not distinguished by its endurance and has difficulty overcoming strong currents. But the moonfish grows to enormous sizes. Some individuals reach 1.5 tons. The moon feeds on jellyfish, squid, eel eggs, ctenophores and plankton.
Ostracion cubicus
The TOP of the most amazing fish continues with the cube box. This inhabitant of the deep sea has a cubic body, which would seem to contradict the laws of evolution. However, such fish live in the Pacific and Indian oceans near coral reefs and maneuver well in the water using their fins. Their main food is small invertebrates and algae.
Broadnose chymaera
In 1909, at great depths at the bottom of the Atlantic Ocean, researchers discovered a jelly-like fish. For its unsightly appearance and characteristic muzzle, it was called the broad-nosed chimera. This fish has been studied very poorly. It is only known that its main diet consists of shellfish.
Frilled Shark
The frilled fish is a shark. It's not enough known species. It was opened in 1884. Externally, the cape bearer looks like a snake or conger eel. There are stripes on the sides of the body, which are gills hidden under the skin. A pair of gills located near the head are connected to each other into a single flesh, reminiscent of a cloak. In the mouth of a deep-sea inhabitant there are several rows of large teeth. Currently, there are no more than 100 individuals left.
Lampris guttatus
Fish maintain their body temperature 10°C higher environment. This gives them incredible energy that helps them overcome long distances.
Seas and oceans occupy more than half the area of our planet, but they are still shrouded in mysteries for humanity. We strive to conquer space and are looking for extraterrestrial civilizations, but at the same time, only 5% of the world's oceans have been explored by people. But this data is enough to be horrified by what creatures live deep underwater, where sunlight does not penetrate.
The chauliod family includes 6 species of deep-sea fish, but the most common of them is the common hauliod. These fish live in almost all waters of the world's oceans, with the exception of cold waters. northern seas and the Arctic Ocean.
Chauliodas got their name from the Greek words “chaulios” - open mouth, and “odous” - tooth. Indeed, these relatively small fish (about 30 cm in length) have teeth that can grow up to 5 centimeters, which is why their mouth never closes, creating a creepy grin. Sometimes these fish are called sea vipers.
Howliods live at depths from 100 to 4000 meters. At night they prefer to rise closer to the surface of the water, and during the day they descend into the very abyss of the ocean. Thus, during the day, fish make huge migrations of several kilometers. With the help of special photophores located on the hauliod's body, they can communicate with each other in the dark.
On the dorsal fin of the viper fish there is one large photophore, with which it lures its prey directly to its mouth. After which, with a sharp bite of needle-sharp teeth, the hauliods paralyze the prey, leaving it no chance of salvation. The diet mainly includes small fish and crustaceans. According to unreliable data, some individuals of hauliods can live up to 30 years or more.
The longhorned sabertooth is another fearsome deep-sea predatory fish that lives in all four oceans. Although the saber tooth looks like a monster, it grows to a very modest size (about 15 centimeters in length). The head of the fish with a large mouth occupies almost half the length of the body.
The long-horned sabertooth got its name due to its long and sharp lower fangs, which are the largest in relation to body length among all fish known to science. The terrifying appearance of the sabertooth earned it the unofficial name - “monster fish”.
Adults can vary in color from dark brown to black. The younger representatives look completely different. They are light gray in color and have long spines on their heads. The sabertooth is one of the deepest-sea fish in the world; in rare cases, they descend to depths of 5 kilometers or more. The pressure at these depths is enormous, and the water temperature is about zero. There is catastrophically little food here, so these predators hunt for the first thing that gets in their way.
The size of the deep-sea dragon fish absolutely does not fit with its ferocity. These predators, which reach a length of no more than 15 centimeters, can eat prey two or even three times its size. The dragon fish lives in tropical zones The world's oceans at a depth of up to 2000 meters. The fish has a large head and a mouth equipped with many sharp teeth. Like the Howlyod, the dragonfish has its own bait for prey, which is a long whisker with a photophore at the end, located on the fish's chin. The hunting principle is the same as for all deep-sea individuals. Using a photophore, the predator lures the prey to maximum close distance, and then with a sharp movement inflicts a fatal bite.
The deep-sea anglerfish is rightfully the ugliest fish in existence. There are about 200 species of anglerfish, some of which can grow up to 1.5 meters and weigh 30 kilograms. Because of its creepy appearance and bad character, this fish was nicknamed the monkfish. Deep-sea anglerfish live everywhere at depths from 500 to 3000 meters. The fish has a dark brown color, a large flat head with many spines. The devil's huge mouth is studded with sharp and long teeth curved inward.
Deep-sea anglerfish have pronounced sexual dimorphism. Females tenfold larger than males and are predators. Females have a rod with a fluorescent appendage at the end to attract fish. Most of anglers spend time on seabed, burrowing into sand and silt. Due to its huge mouth, this fish can completely swallow prey that is twice its size. That is, hypothetically, a large individual anglerfish could eat a person; Fortunately, there have never been such cases in history.
Probably the strangest inhabitant of the deep sea can be called the bagmouth or, as it is also called, the pelican-shaped largemouth. Due to its abnormally huge mouth with a bag and a tiny skull in relation to the length of the body, the bagmouth looks more like some kind of alien creature. Some individuals can reach two meters in length.
In fact, bagmouths belong to the class of ray-finned fish, but these monsters do not have too many similarities with the cute fish that live in warm sea backwaters. Scientists believe that the appearance of these creatures changed many thousands of years ago due to their deep-sea lifestyle. Bagmouths have no gill rays, ribs, scales or fins, and the body is oblong with a luminous appendage on the tail. If it were not for the large mouth, the bagmouth could easily be confused with an eel.
Bagworms live at depths from 2000 to 5000 meters in three world oceans, except the Arctic Ocean. Since there is very little food at such depths, bagmouths have adapted to long breaks in eating, which can last more than one month. These fish feed on crustaceans and other deep-sea brethren, mainly swallowing their prey whole.
The elusive giant squid, known to science as Architeuthis dux, is the world's largest mollusc and is thought to reach a length of 18 meters and weigh half a ton. To date, a live giant squid has never been captured by humans. Until 2004, there were no documented sightings of live giant squid at all, and the general idea of these mysterious creatures It was based only on the remains washed ashore or caught in fishermen’s nets. Architeuthis live at depths of up to 1 kilometer in all oceans. In addition to their gigantic size, these creatures have the largest eyes among living creatures (up to 30 centimeters in diameter).
So in 1887, the largest specimen in history, 17.4 meters long, washed up on the shores of New Zealand. In the next century, only two large dead representatives of the giant squid were discovered - 9.2 and 8.6 meters. In 2006, Japanese scientist Tsunami Kubodera managed to capture on camera a living female 7 meters long. natural environment habitat at a depth of 600 meters. The squid was lured to the surface by a small bait squid, but an attempt to bring a live specimen on board the vessel was unsuccessful - the squid died from multiple injuries.
Giant squids are dangerous predators, and their only natural enemy is adult sperm whales. There are at least two described cases of fight between squid and sperm whale. In the first, the sperm whale won, but soon died, suffocated by the giant tentacles of the mollusk. The second fight took place off the coast of South Africa, then a giant squid fought with a baby sperm whale, and after an hour and a half fight, it still killed the whale.
Giant isopod, known to science, like Bathynomus giganteus, is the largest species of crustacean. The average size of a deep-sea isopod ranges from 30 centimeters, but the largest recorded specimen weighed 2 kilograms and was 75 centimeters long. In appearance, giant isopods are similar to woodlice, and similar giant squid are a consequence of deep-sea gigantism. These crayfish live at a depth of 200 to 2500 meters, preferring to bury themselves in silt.
The body of these creepy creatures is covered with hard plates that act as a shell. In case of danger, crayfish can curl into a ball and become inaccessible to predators. By the way, isopods are also predators and can feast on a few small deep sea fish And sea cucumbers. Powerful jaws and durable armor make the isopod a dangerous opponent. Although giant crayfish love to feast on live food, they often have to eat the remains of shark prey that fall from the upper layers of the ocean.
The coelacanth or coelacanth is a large deep-sea fish whose discovery in 1938 became one of the most important zoological finds of the 20th century. Despite its unattractive appearance, this fish is notable for the fact that for 400 million years it has not changed its appearance and body structure. In fact, this unique relict fish is one of the oldest living creatures on planet Earth, which existed long before the appearance of dinosaurs.
Coelacanth lives at a depth of up to 700 meters in the waters of the Indian Ocean. The length of the fish can reach 1.8 meters with a weight of more than 100 kilograms, and the body has a beautiful blue tint. Since coelacanth is very slow, it prefers to hunt great depths, where there is no competition with faster predators. These fish can swim backwards or belly up. Despite the fact that the meat of the coelcanth is inedible, it is often the target of poaching among local residents. Currently ancient fish is in danger of extinction.
The deep sea goblin shark, or goblin shark as it is also called, is the most poorly studied shark to date. This species lives in the Atlantic and Indian Oceans at depths of up to 1300 meters. The largest specimen was 3.8 meters long and weighed about 200 kilograms.
The goblin shark got its name due to its eerie appearance. Mitsekurina has movable jaws that move outward when bitten. The goblin shark was first accidentally caught by fishermen in 1898, and since then 40 more specimens of this fish have been caught.
Another relict representative of the sea abyss is a one-of-a-kind cephalopod-detritus feeder, which has external resemblance, both with squid and octopus. Yours unusual name the hellish vampire received thanks to the red body and eyes, which, however, depending on the lighting, can be blue color. Despite their terrifying appearance, these strange creatures They grow only up to 30 centimeters and, unlike other cephalopods, they eat exclusively plankton.
The body of the hellish vampire is covered with luminous photophores, which create bright flashes of light that scare away enemies. In case of exceptional danger, these small mollusks turn their tentacles along the body, becoming like a ball with spikes. Hellish vampires live at depths of up to 900 meters, and can thrive in water with an oxygen level of 3% or lower, critical for other animals.
Our immense globe inhabited by various living creatures. Living creatures live wherever possible, including occupying all water places (oceans, seas, lakes and rivers). It is also curious that a certain part of the population does not know about the existence of some species.
A very long time to study aquatic fauna was basically impossible due to the lack of necessary technical gear and equipment.
Many people know the well-known Jacques Cousteau, a researcher who once invented scuba gear. With the help of this suit, it became possible to closely and much more thoroughly examine the bottom of any deep body of water. In the future, when developing other devices to help dive into the ocean, Cousteau’s invention was taken as a basis.
Below we will talk about the most striking and extraordinary inhabitants of the deep sea. So:
An incredible lion fish, it is rightfully considered to be quite attractive in appearance and an interesting inhabitant of the seabed. However, touching it is highly discouraged, since its needle-sharp fins contain poison that is fatal to humans.
Foliar sea dragon, in its image is somewhat similar to a seahorse. The length of this wonderful beauty is up to 35 cm. It has a rich green color, which makes it virtually invisible among plants of the same color.
Pelican fish (length up to 1 m). A rather extraordinary fish - it’s all about the front part, which is the mouth, exactly half the size of the whole body. It will easily eat prey twice its size - this is explained by the elasticity of its stomach, which has the ability to stretch to large scale parameters.
The bagfish is a rather dangerous inhabitant of the seabed. Its body length is about 35 cm, and it also has a fairly flexible stomach, thanks to which it is able to swallow prey no less than 4 times longer than its own height and 10 times heavier than its own body weight.
The barrel eye is a fish that attracts attention because of its transparent head and amazing eyes that look exclusively upward. Thanks to the green color of the eye shell, the brightness of light perceived by the fish is significantly reduced, this allows you to quickly distinguish prey and also quickly catch it. These creatures move extremely slowly and prefer to live at depths of up to 800 m.
Moonfish - has a huge size and round shape. It is noteworthy that she does not know how to swim at all, for this reason frequent place its habitat is the shore of a reservoir. The weight of this miracle of nature sometimes reaches unimaginable sizes - 1.5 tons! to his appearance it most closely resembles a disk - the tail is short and pointed, and the skin is covered with tubercles.
Dragon fish is black in color and is one of the most dangerous inhabitants of the sea surface. It prefers to live at a depth of up to 2,000 m. The body length is about 40 cm. However, these parameters apply only to females, and males are very small, their body length never exceeds 5 cm. Long mustache and teeth are all they need for catching prey.
Tiger goliath fish. Habitat - r. Congo. This type of living creature is also deadly dangerous creatures, because it belongs to the piranha family. Its parameters are as follows: body length - 180 cm, body weight - 50 kg.
It is extremely difficult to catch a Goliath in a net, since its sharp fangs and strong jaw can easily bite through any net. It is also noteworthy that this fish can choose any bottom inhabitant as prey, regardless of its parameters, even predatory crocodiles.
Silver locomotive - habitat is both Atlantic and Pacific Oceans. Perhaps this is the most dangerous inhabitant of the seabed, since the poison that is contained on her body is capable of killing not only a person, but also any living creature that comes into her field of vision. The length of the Silver Locomotive is 45 cm. In addition to the outer skin, internal organs, such as the liver, for example, also contain poison.
Monkfish. Habitat: Atlantic and Antarctic oceans. It is considered one of the most terrible inhabitants of the reservoir, because of its huge jaw and fairly large length - 1 m. In fact, the prey itself swims into its paws, figuratively speaking, and this is explained simply - the monkfish has a luminous end of the spine.
Interesting fact: Males, after a certain time, completely lose the ability to digest the prey they swallowed, and then they transform into females.
Tripod fish - it owes this name to the presence of 3 “legs”, which are long fins (1 m), facilitating comfortable movement and stability. Habitat: warm tropical waters. Unlike most of their kind, the tripods are quite small, only up to 35 cm in length. Thanks to their inherent bioluminescence, fish have an excellent ability to glow in the dark. In color they come in both dark brown and black.
Bonus: we can’t help but say about our pride - the omul from Baikal
Baikal omul belongs to the salmon family. As centuries-old shows scientific research In the field of genetics, this subspecies of fish is very close to the classic and herring whitefish. At the moment, it is completely distinguished as an independent species - Coregonus migratorius.
Lake Baikal is its most common habitat. Less often it can be observed in Siberian and Ural reservoirs. To date, as many as 4 of its populations have been officially recorded:
- Severobaikalskaya
Posolskaya
Selenginskaya
Chivyrkuiskaya.
Barguzinskaya (but it is distinguished extremely rarely)
Classic omul rarely weighs more than 800 grams, however, there are exceptions. So, sometimes it was possible to see this fish with a length of 47 cm and a body weight of almost 1.5 kg! The life expectancy of omul is quite high - 18 years. In the entire history of studying this type of fish, the largest specimen of the Selenga population was encountered, with a body weight of 5 kg and a body length of 50 cm. And you can purchase fresh frozen omul on the website sibifood.ru. The Power of Siberia is an online store of high-quality fresh game and fish directly from Yakutia and Krasnoyarsk.
A person still knows very little who lives in ocean depths, but even our knowledge is enough to understand that, in addition to cute fish, the most nightmarish creatures swim there. At least we can make the TOP 10 scariest fish in the world, keeping them in mind appearance or habits.
1. White shark
As far as we now know, the most terrible fish in the world's oceans is white shark. This is very ancient look huge and bloodthirsty. The size of the white shark is such that any prey is sea creatures, except killer whales and large whales. Human meat is also included in her menu, but not often - as a delicacy. The huge mouth of the white shark hides several rows of very sharp teeth, which are constantly renewed throughout its life. The length of a white shark can reach up to 10 meters, and it can easily bite a large prey - a seal or a person - in half.
2. Long-horned sabertooth
If we take into account solely the appearance, the most terrifying looking fish is the long-horned sabertooth, also known as the common sabertooth and the common needletooth. She actually looks quite scary and not very nice. This fish has a disproportionately large head. The body of adults is black. Long thin teeth protrude from both jaws of the fish. It is interesting that in appearance young saber-tooths are very different from adult individuals, so scientists for a long time even classified them as a different species. They have a different body structure, pointed spines on the head and a lighter color, and they live at shallower depths.
These gargoyle-like fish live in the great depths of the Pacific, Indian and Atlantic oceans in tropical and subtropical latitudes. These horror stories feed on crustaceans, small fish and squid. The young growth of the long-horned sabertooth itself is food for larger predators: tuna and no less terrible alepisaurs.

3. Drop fish
Off the coast of Australia and Tasmania, at very great depths (presumably 600-1200 meters), there is a drop fish, which is also included in the list of the most terrible fish. More precisely, she is not so much scary as unattractive and to some extent disgusting-looking. Local fishermen call it the “Australian goby.”
The fish resembles at the same time the dissatisfied senile face of a person and some semblance of an embryo due to its watery, slippery body. However, it does not pose a danger to humans, if only because a person never appears at a depth of a kilometer, and fish do not swim near the surface. The blobfish does not have a swim bladder. The expression on the “face” of this fish is sad, even sad. This fish is inedible, but lately It is increasingly being caught by fishermen, which is why scientists have begun to fear for the safety of this species - maybe that’s why the blobfish is grieving so much? It will take at least a decade to restore its population.
4. Brownie shark
The goblin shark (Mitsekurina, Scapanorhynchus) also lives at great depths, but its population is probably small. At least to date, only a few similar specimens have been caught (less than 50 fish). Scientists have no idea about the habits of this mysterious deep-sea monster. So far they have only been able to establish that this species lives in the warm waters of all oceans at a depth of more than 200 meters. This shark is sometimes called the “goblin” for its terrifying appearance with a huge growth on its head and protruding, almost Alien-like jaws. Collectors of natural wonders greatly value such jaws.
5. Coelacanth
The coelacanth fish is an incredibly ancient species, considered a living fossil. Over hundreds of millions of years, it has changed little in its structure. The coelacanth has an eerie appearance, but it is not a very active fish and spends a lot of time in underwater caves.
At the moment, two species of coelacanth have been found, one lives in the southwestern Indian Ocean, off the coast of South Africa, and the second was discovered at the very end of the last century near the island of Sulawesi. Coelacanths are covered, like armor, with powerful scales, which are good protection for them. The scales of coelacanths are unique, like no other modern fish; on its outer surface there are many protrusions that make the scales look like a file. Coelacanths feed on coelacanths, anchovies, cardinal fish, cephalopods, cuttlefish and even big-headed sharks.

6. Monkfish
Fish monkfish or the European anglerfish is not uncommon; it lives along almost the entire European coast, from the Black Sea to Barents Sea. The fish was named so because of its ugly appearance - a naked, scaleless body, a huge head with a large mouth.
This monster is capable of glowing in the darkness of the deep sea - a luminous rod-like outgrowth looms in front of the fish’s mouth, which lures prey to itself. This fish belongs to the order of anglerfish, and if you consider that it reaches an impressive two-meter length and a human weight of 60 kg, it is easy to imagine how such a monster can scare.
7. Viper fish
The frightening appearance has become the main reason for the popularity of the viper fish: a long thin body with luminous points, a disproportionately large mouth dotted with needle-sharp teeth, a luminous fin - a fishing rod that lures simple-minded victims into this mouth. The habitat of this fish is extensive - Quiet and atlantic oceans. But in this case, this fish is quite small - only 25 centimeters long.
This small predator also deep-sea - it lives at about a kilometer depth, and if necessary, it can even descend into a 4-kilometer abyss. But this nocturnal predator hunts near the surface for small fish and other living creatures, after which it again plunges into the less populated depths of the ocean, where it can feel relatively safe.
8. Wart (stone fish)
Divers see a wide variety of rocks on the seabed, varying in color and shape. However, some stones may move unexpectedly. This is how the wart, the most poisonous fish in the world, mimics a reef stone. The body of the fish is covered with soft skin with bumps, like warts, which helps it skillfully camouflage itself on the bottom, pretending to be an inconspicuous stone. But the sharp poisonous dorsal fins of this fish are especially dangerous, for which it is also called the wasp fish, and Australian aborigines They called her the warty vampire.
The length of an adult wart can reach 40 cm, although some divers claim to have met half-meter warts. The color of the stonefish can vary from brown to green, with reddish-orange spots. Despite its danger and repulsive appearance, the wart is an edible fish from which sashimi is prepared. But the spines on the dorsal fin can easily pierce shoes and injure the leg, which often ends in the death of a person.

9. Big tiger fish
This predatory freshwater fish is also called the giant hydrocin or goliath, and the locals call it mbenga. The predator's mouth is armed with a rare but impressive 32 fangs, reminiscent of crocodiles. It can easily not only bite the fishing line, but also the rod or the hand of a careless fisherman. Goliath is named so not by chance - it is one of the largest freshwater fish in the world, which can weigh up to 100 kilograms. This monster lives in Central Africa, in the Congo River basin and Lake Tanganyika. In the Congo, there have been cases of river giant attacks on people. Locals they assure that Mbenga is the only fish, not afraid of a crocodile.
10. Characin Vampire
The payara or characin fish lives in the Amazon River basin. But it also has another sonorous name - “vampire” for its two incredibly long lower fangs, with the help of which it holds its prey (usually smaller fish). This fish is a coveted trophy for professional fishermen. Adult fish grow in the Amazon up to one and a half meters in length, but weigh relatively little - 14 kilograms. The lower fangs, which gave the characin the name “vampire,” can grow up to 16 centimeters. With the help of such a formidable weapon, the fish is able to reach deeply hidden internal organs the attacked victim, since it accurately determines their location.
The world of the deep sea constantly reveals more and more unexpected representatives and inhabitants to man. New discoveries are facilitated by modern advances in technology, such as bathyscaphes, sonars and new types of scuba gear, which make it possible to reach places that were previously unexplored. Oceanologists study the fauna of the sea and ocean, which is replete with unusual, colorful fish or those that lead an amazing lifestyle. You can get acquainted with the most interesting of them in this article.
Sea horse
Looking at this creature, one cannot dare to call the seahorse a fish. Rather, the word “animal” comes to mind, although this is a real fish from the family pipefish. Flock seahorses is a funny sight, since they like to rest, attached with their curved tails to the seaweed, on which they swing smoothly, like on a swing.
The hooks and spines present on the surface of the body are not needed for decoration, but in order to successfully get lost in the thickets of algae and become invisible to predators. The shape of the oral apparatus is also interesting: a tubular outgrowth in the form of a short proboscis functions as a medical pipette, thanks to which sea horse can draw in plankton.
In the world of fish, the way this creature moves is extremely rare: the body is in a vertical position or located slightly diagonally. This happens because the swim bladder is shifted to the upper part of the body. The jumping movements up and down when moving fully justify the name of the genus - seahorse. It seems that the fish is not swimming, but jumping.
The issue of bearing offspring is also interesting. It has been proven that in these representatives of the marine fauna all responsibilities for bearing eggs and fry are assigned to the males, who have a special organ for this purpose - the brood chamber. It is a functional analogue of the uterus, where the eggs perfectly develop into fry.
These fertile creatures can give birth to up to several thousand babies at a time, but childbirth is often long and painful, and often ends in the death of the male.
This creature is a favorite meme of Internet users. Such an appearance really cannot leave anyone indifferent: it seems that nature was practicing creating caricatures.
The blobfish holds the title of the scariest fish in the world, although most people consider it funny and even cute. It is not only the appearance of the drop fish that is interesting, but also its lifestyle. In order not to waste a lot of energy, it has a slightly lower density than sea water. This allows you to swim with virtually no effort. In fact, it is carried by the current from side to side, and only when strong desire she can set herself a certain direction.
This lifestyle greatly reduces the need for energy expenditure and food consumption. The drop fish does not chase its prey, it simply opens its mouth and waits for tasty crustaceans and mollusks without shells to get there.
Recently, these representatives of the depths of the ocean have become a sought-after souvenir among vacationers, therefore, despite the fact that the meat is completely tasteless, they are in danger of a sharp decline in their numbers. Lazy fish reproduce slowly, so population restoration takes a long time.
Another creature that cannot be called handsome. Largemouth are found at depths of half to three kilometers. His interesting shape body resembles an eel. The length of the largemouth reaches a meter, but even with such immodest parameters the head looks disproportionately large. The main distinguishing feature is the huge mouth, which opens as wide as that of a pelican. The ligaments between the jaw bones are simplified, which makes the amplitude of the joint as large as the skin allows.
An interesting fish would be too heavy and would not be able to swim if such a gigantic head also had a heavy skeleton. But nature has provided for everything, so the largemouth does not have a full-fledged skeleton; it makes do with a pair of hollow bones. To lighten the weight, this creature also lacks the scales that protect the body in most species.
The fins are poorly developed, so largemouth cannot swim with high speed. But with such a huge mouth, you can simply open your mouth and slowly move in the abyss, expecting the prey to fall inside on its own. An interesting fact is that with such an aggressive and intimidating appearance, the largemouth has a very calm and timid disposition. He will not enter into a fight, but will prefer to retreat as quickly as possible.
Anglerfish
This fish contains everything that might be interesting: unusual appearance and an amazing way of life. Nature has rewarded the anglerfish with a scary appearance that can cause horror in inexperienced explorers of the deep sea. A characteristic feature is the presence of a special organ in the form of a fishing rod attached to the front of the head.
The angler fish is a predator that lives at a depth of 1.5-3 km, where light does not penetrate. Thanks to complex biochemical processes, the growth on the head begins to glow when the fish feels hungry. Small fish swim to this alluring light and become food for an unusual predator.
Particularly interesting is the sexual behavior of the anglerfish. Males of this species look completely different: while females can reach sizes up to 65 cm, males rarely grow more than 3 cm. Their independent life continues until puberty, after which the male finds a female, copulates with her, and then bites into her body teeth.
Over the course of a few days, the organisms of the male and female merge into general structure, the male’s brain is completely reduced, the organs of vision, lips, and tongue disappear, leaving only the organ that produces the seed. This appendage of the female functions until she dies.
Fish with legs
The study of the ocean does not stop for a minute and constantly brings new surprises and surprises. In early 2018, a completely new species was discovered that has legs. The amazing luck lies in the fact that such a representative was not discovered in a single copy. A group of divers diving in the warm waters of Tasmania immediately noticed a whole school of fish. This immediately dismissed all possible versions that the creatures were simply the fruit of a genetic mutation of another species.
Scientists identified them and named them Thymichthys politus. This species belongs to the Branchionichthyaceae family and is considered one of the rarest in the world. Experts from the Institute of Marine and Antarctic Research, who are working on studying this species in Australia, consider the meeting to be an incredible success.
The main distinguishing feature of these creatures is the presence of modified fins, which are devices for walking on the ground. It does not move on land, but it walks quite confidently along the ocean floor. At the same time, her eyes do not see at all.
The interesting structure of the fins allows Thymichthys politus to go in the chosen direction even near waterfalls with strong currents, where other drifting creatures are thrown back by the current.
From an evolutionary perspective, such a find is of great value, since it demonstrates how ancient nature millions of years ago there was a gradual transition from a completely aquatic type of habitat to the conquest of land.
In order not to cause unnecessary excitement, scientists chose not to report the exact coordinates of the places where this find was discovered. The scientific world rightly fears that this information could cause an influx of tourists and disruption of the fragile ecosystem in which prehistoric fauna have survived to this day. But on the Internet you can find a sufficient number of photos and even videos of individual specimens of Thymichthys politus.
The amazing discoveries did not end there. It turned out that the eyes are able to change their position, due to which the range of vision that they perceive completely changes. When the smallmouth macropinna tracks prey swimming above, the eyes rise vertically, but if it needs to see what is in front or in the mouth area, the eyeballs move forward to the horizontal plane. This interesting mechanism gives the macropinna a great advantage in searching for food.
This fact was not noticed immediately after the discovery of the fish because it was taken from fishing nets, in which the membrane covering the organs of vision was damaged. Only research with bathyscaphes allowed scientists to establish the truth.
Moonfish
A representative of marine fauna, who was considered one of the deities different nations world - moon fish or sun fish. She was compared to round celestial bodies due to the characteristic shape of her body. This creature reaches enormous sizes, sometimes weighing more than 2 tons. At the same time, its fins are quite small and are shifted towards the tail rounded part, because of this it is very difficult for the giant to swim, which forces the moonfish to drift in the coastline of warm waters. To make a turn in the other direction, a huge jet of water is released from the mouth under pressure, which creates jet thrust.
Its light skin and disc-shaped body without scales makes it unusual and defenseless in appearance. This prehistoric representative of marine fauna is considered the most prolific among all famous fish. The number of eggs that a female produces at one time reaches 300 million. Another interesting fact is that the fry of this giant are very small after birth - no more than 2 mm. After this, rapid growth begins, during which the young animals can gain about half a kilogram of weight per day.
An interesting representative of the aquatic fauna - the Anabass - is capable of destroying all ideas about fish, which, as we know, cannot exist without water. With the discovery of this species, it became clear that they can and do this successfully. Moreover, it is surprising that the climbing perch can climb trees.
Ichthyologists have found that in the moisture of the foliage, the Pineapple is looking for a place where it can wait out a temporary drought. In order to crawl on the ground or bark, it has very hard and durable scales that protect the abdomen from mechanical damage. The lower paired fins are used for repulsion, and in order not to fall from vertical surfaces, small spines grow on the gill plates, which work like ice picks for a climber.
It is worth stating the fact that the Pineapple does not really like to make such trips. If the reservoir dries out gradually, it will prefer to bury itself in the thickness of the silt, where the moisture will be retained. To reliably protect oneself, a sealed cocoon is created around the body, inside which there is water. But if the reservoir drains quickly, then the persimmon goes in search of a new home. On dry ground it can cover about half a kilometer, and this fact is simply amazing, since with a small body size such a distance is enormous.
