Amazing examples of animal behavior
Perhaps, after reading this article, many will consider it nonsense. In fact, not all animals behave as simply as many people think, some of them are able to surprise anyone with their behavior. The unusual behavior of animals is associated with genetics, and sometimes with copying their parents and older individuals. This article will discuss the most strange and unusual animals on the planet and their behavior.
Unusual animal behavior - TOP-10 jokes
flatworms
Unusual animal behavior - in flatworms
At first glance, it seems that worms cannot be smart and quick-witted, but it is their mating season the most unusual. Worms are hermaphrodites, so before they start mating, males arrange fencing with penises, as a result of which the winner gets the female. The worm whose penis is larger and stronger wins. Each worm tries by all means to become a “real man”, and then leave its offspring to the loser, who will take care of him.
Elephants have unusual animal behavior...
These giants are very smart and kind creatures. It is elephants that have a rich emotional life, which is only worth their funeral procession. Elephants are very kind to each other, so after death they take care of the body of their relatives and friends. The deceased is sprinkled with branches, flowers and leaves to hide his body. In the future, elephants do not forget about them, so they constantly go to where the remains of elephants are, even if the weather is terrible, and they are hungry or sick. There are cases when elephants buried people in the same way.
horned lizard
Unusual animal behavior - in horned lizards ...
These cute lizards are very smart creatures that have developed a special way of protection. This method is a little creepy and even scary, however, for a lizard it is the only way survive. When she realizes that there is no way to get away from a predator, she splashes him in the face with jets of blood from her eyes. As a rule, her pursuer runs away in surprise, tail between her legs.
Bowerbird
Unusual animal behavior - in bowerbirds ...
These birds are incredibly talented designers. It is a beautifully built house that helps males attract a female. The bower house is decorated with flowers, shells, feathers, pebbles and other decorative elements that turn their nest into a cozy hut. If there are birds that do not want to work, hard workers take their material and use it to equip their home. It is rather surprising that bowerbirds always steal decor elements of exactly the same color from their relatives.
Adelie Penguin
Unusual animal behavior - Adélie penguins ...
Of all the animals that live in Antarctica, it is penguins that are distinguished as the most unusual. In order to win the female, the male takes a large stone in his paws and brings it to his chosen one, and if she reciprocates, she begins to sing loudly and beautifully. Then the lovers leave the flock for a while in order to devote more time to themselves, so to speak, arrange a honeymoon.
Zebra amandine
Unusual animal behavior - zebra Amadins ...
Little birds are famous for their attachment to their partners. These beautiful creatures groom and cherish their partner, and then take care of their offspring together. In addition, these birds have something that distinguishes them from other winged creatures. If the male turns out to be sick or not strong enough, the female deliberately incubates larger eggs so that the future offspring will be healthy, strong and strong. It is surprising that the birds are not embarrassed by the shortcomings of the chosen one, they remain with him until the end of their days.
Unusual behavior of animals - trout fish ...
Everyone knows what an orgasm imitation is, because people often use this phenomenon. As it turns out, they are not the only ones who have succeeded in this endeavor. Brown trout is a type of fish belonging to the salmon genus. Scientists managed to find out that the brown trout is able to imitate an orgasm when she needs to deceive the male. Thus, the female tries to stimulate a longer ejaculation in him.
Unusual animal behavior - common cuckoo ...
Today, for most people, the cuckoo is associated with a bird that gives away its children, which is why unlucky mothers are called that. Cuckoos do not like to make any commitments, so at the first opportunity, these cunning and lazy creatures transfer their eggs to another nest where the chicks can be taken care of.
Dung-beetle
Unusual animal behavior - dung beetle ...
The beetle got its name because of its love for the excrement of other animals. This is where they spend most of their time. Manure is perfect place for these beetles, because it fully satisfies their needs. There they lay their eggs, take care of their offspring, and then feed them to their offspring. To attract a female, the dung beetle begins to roll a lump out of ... The more lumps, the cooler the groom! To a modern person, this way of life will seem disgusting, but the ancient Egyptians considered dung beetles to be sacred animals, which is why they worshiped them.
Naked digger
Unusual animal behavior - a naked mole rat ...
This creature has a very unusual appearance, which even scares some. In addition, they also have amazing qualities, such as the absence of pain and composure. The social structure of these bald rodents is very similar to that of bees. largest female becomes a mother, as a result of which only she can create offspring. To get rid of rivals who are constantly trying to steal suitors from the queen, she intimidates them with her harsh and aggressive behavior, which leads to hormonal disruptions that block the reproductive system of smaller females.
In general, the animal kingdom is a fairly practical world. Animals have to be practical, given that their the main task is to survive. When you're worried about how you'll find your next meal, whether or not you can pass on your genes to the young, and what's lurking around the corner to eat you, there's simply no time for creativity. However, there are certain types of animals that behave absolutely extraordinary. Some of their actions shock scientists, while others baffle. Below is a list of ten examples mysterious behavior animals that scientists can't explain.
10. Fur seals mating with penguins
In 2006, researchers observing the endemic animal species of Marion Island in Antarctica saw something that puzzled them - a fur seal was trying to mate with a royal. They noted the incident in their study, but considered it an extraordinary and unique incident. At the time, they thought it was an accident, maybe a Navy SEAL game that turned out to be weird, or maybe he was in a mood before eating.
However, in recent times Representatives of the Mammal Research Institute at the University of Pretoria, South Africa, have noticed that this is happening again. And again. And again. Such attempts are always brutal and in at least one case ended with a fur seal killing and eating a penguin.
Until 2006 seals and their closely related species have never been seen trying to mate with anything other than their own. own classification, so it seems that they are learning this somewhere. Scientists have been carefully monitoring the island for 30 years and have studied almost thoroughly not only the island itself, but also all its inhabitants. That is why such abrupt and strange behavior has truly puzzled scientists.
There are several assumptions about what is happening. However, they are all just guesses. The lack of females on the beach may cause young males to direct their attention to other places, however, the typical reasons for wanting to mate with another species are absent in this case. In some cases, interspecific mating can produce hybrid young, as in the case of mules, but in this case it is absolutely impossible.
9. Collective apathy of baboons
In 2013, the usually restless baboon colony at the Emmen Zoo in the Netherlands was struck by a bizarre case of mass hysteria. They stopped all their usual antics: games, fights, greetings from their caretakers. They just sat down and sat in silence.
The strange event began with a huge outbreak of chaos, which suddenly stopped. One group sat high in a tree and refused to do anything, and apathy spread throughout the colony. This is not the first time this has happened. In 1994, 1997 and 2007, similar cases of mass apathy occurred with other groups of baboons. During previous case they all sat motionless in their enclosure, looking in the same direction. They didn't eat or talk to each other. They just sat. Nothing like this happened in any other zoo. The event was also unrelated to unique quality or a character trait of the dominant member of the pack, since in all these cases the leaders of the colony were different.
Very slowly, the baboons began to come out of their trance state. The young baboons began to fool around again, the older ones took up their parental duties, and gradually they all began to look for food again.
There are many theories about what exactly causes this condition in baboons. The reason may be minor, such as small earthquakes or a random fright from the fact that one of the visitors came in a scary T-shirt for them. Despite the abundance of such theories, none of them has been proven. And the baboons at the Emmen Zoo had already returned to their usual activities at that time.
8 Blue Whale Song Changes
For decades, scientists have recorded the songs of blue whales in the ocean. However, on this moment something strange is happening not with the songs themselves, but with the whales. Every year their voices get deeper and deeper.
The tone changes so dramatically that songwriters have to readjust their equipment every year to make sure they can record the songs. Recorders turn on when they detect a certain frequency, and that frequency changes.
This is happening all over the world. And not with one specific group of whales, but with whales in all oceans. The singing voices of the whales are getting deeper and deeper. Scientists first noticed changes in their tone in the 1960s, and since then the whales' tone has deepened by about 30 percent.
Nobody knows why this is happening. Some think that this is due to the need to overcome competing ocean noises that have increased over the past few decades, while others believe that this may be a response to changes in water temperature, its composition or climate in general. Perhaps this behavior is due to a change in the size of the whale population or the way they choose their partners for mating. Nobody can say for sure.
7Gender-Changing Chickens
There are several species of animals that change sex, usually when there are no members of the opposite sex in the population. In this case, gender change makes sense for the survival of the group. However, in the case of sex change by chickens, this process is slightly different.
Hens cannot physically change sex, however they adopt the mannerisms and appearance of cockerels, that is, they are not really cockerels, but they adopt their secondary sex characteristics. Scientists know how this happens, but they don't know why.
In chickens, there are two genital organs: in females, one develops into an ovary, and the second remains in a dormant state. If something happens, such as a hormonal imbalance or the development of a cyst, a second organ develops and releases male hormones.
What happens to a chicken that undergoes such changes? She suddenly stops laying eggs, grows her earrings and comb, and behaves like a rooster. She also begins to strut and crow importantly, however she will not attempt to mate with other hens as she is still genetically a female.
This happens, although not often. In 2011, chicken coop owners in Cambridgeshire, England, saw it firsthand in their backyard when one of their hens stopped laying eggs and started crowing. Gertie became Bertie. Although initially crowing was not easy for the newly minted Bertie, over time he became a dignified and vociferous half-rooster.
6 Glow In The Dark Scorpions
When scorpions are exposed to ultraviolet light or strong light The moons, they glow. No one knows why they glow, but for scorpions it is dangerous.
Scorpions hunt at night, at the same time those creatures that eat them hunt. Owls and some rodents leading night image life, prey on scorpions, so it seems rather counterintuitive that they glow in the dark - this is not the best survival tactic.
Part of the answer lies in the eyes of scorpions, which are designed to best perceive green-blue light. It is possible that their ability to glow in the dark evolved as a way to spot each other. There is also an assumption that they act in the same way as deep sea creatures, luring prey with their bioluminescence.
A California State University researcher has theorized that scorpions rely on their glow to tell when they are in plain sight and in danger. When the glow ends, they presumably realize that they are in the shadow of something that hides them from the moonlight and thanks to which they are safe. The strength of their glow indicates whether others can see them or not.
5. Dolphins and whales washed ashore 
In 2009, a group of killer whales washed up on a beach in South Africa. There were 55 individuals in the group, and rescuers tried to return them to the water as soon as possible. However, as soon as the rescuers pushed the huge creatures back into the water, they again swam to the shore. They began to throw themselves on the beach in the morning and by noon it was decided that the most humane solution to the problem was to euthanize them.
There are many stories about mass emissions ashore associated with activity navy, underwater noise caused by cargo ships and even pollution. While all this may have some effect on such strange animal behavior, such cases were recorded long before all these human inventions appeared. There are records of mass strandings in New England, shortly after the first settlers arrived there. Even Aristotle described cases when sea animals washed ashore.
From all this it follows that, despite the fact that the situation may be aggravated modern technologies, such as a sonar, this can also be a natural behavior and does not make any sense at all. It is possible that sick animals are washed ashore to die, but this does not explain why large groups do this at the same time. The record of such behavior is the case when 835 individuals of small killer whales struggled not to be prevented from being washed ashore.
4 Rhino Riding Genets
The geneta is a small, cat-like animal, endemic to North Africa. They are traditionally solitary animals, and although their territories may sometimes overlap, they spend most of their time alone. This does not apply to one particular genet that has been seen in the Hluhlwe-Imfolozi Game Reserve in South Africa. This geneta not only made incredible friends, but rode on their backs every night.
3. Crocodile tears
The very idea of crocodile tears is rather strange. Folklore has long told us that crocodiles cry when they eat, presumably because they feel bad about killing another animal. This phrase is often used in literature to refer to insincere expressions of emotion. The first mention of the phenomenon is believed to come from a text written in the 1400s called The Voyage and Travel of Sir John Mandeville which tells of crocodiles and their tendency to weep while how they eat people.
The idea of crocodile tears as scientific fact was incredibly difficult to prove, since most crocodiles aren't the easiest animals to study up close, and they tend to feed in the water. The possibility of the existence of crocodile tears has always been dismissed and considered a myth. This notion was also backed up by a questionable study from the last century, in which a researcher tried to test whether crocodiles could cry by rubbing a crocodile's eye with an onion. The crocodile did not cry.
And only recently, zoologists from the University of Florida (University of Florida), who studied relatives of crocodiles - alligators and caimans, discovered that crocodile tears are not a myth at all, and they really cry while eating. Scientists just don't know why.
Scientists agreed that this is not an emotional response to anything, but a physiological phenomenon. Tears can be caused by the sounds the animal makes while eating, the air passing through the holes in their skull, or the pressure they have to apply to bite through their prey. They can also be a self-defense mechanism, like ours. own tears. Their eyes produce tears as a way to protect their eyes during the struggle that occurs while they are catching their prey.
The exact explanation will be found with further research, but there is a huge problem in the way of scientists. To see what's going on, someone would have to train crocodiles to eat on land. However, based on the fact that they are killing machines with deadly teeth, no volunteers have yet been found.
2. Go to the toilet with sloths
Looking at sloths, it's hard to imagine anything that can make them put in any effort. However, scientists have found that they spare no effort and energy to go to the toilet.
Most of the life of sloths passes on the crowns of trees. It's where they eat, where they sleep, and in general, it's the safest place for these slow-moving creatures. Once a week, however, sloths make the slow, laborious descent downstairs to go to the bathroom. When the job is done, they again climb to the top of the tree. No one knows why they put in so much effort to get down to earth. After all, this not only takes a lot of energy, but is not the safest activity for them. It would be much easier if they stayed in the trees, out of the reach of predators living on the ground, and did what they need right up above.
There is one main theory as to why they do this, and it has to do with the insects that live in their fur. The coat of sloths is rather poor and full of sloth fires. The researchers hypothesized that the sloths make the long descent down to have the moths lay their eggs in their feces, and then when the insects hatch, the young can find a sloth nearby.
The disadvantage of this theory is that scientists cannot explain what benefits the sloth has from these insects. No evidence has been found to support that sloths benefit in any way from a bunch of insects. These insects create conditions for the growth of algae that cover the sloth's fur, but this also does not bring obvious benefits to the animal.
1. Bully Elephants
Few groups can boast such cohesion as elephants. They help raise each other's babies, protect each other, and mourn the loss of a close friend when they die. However, a strange observation has recently been made about the behavior of elephants, in particular elephants. This observation suggests that all is not well in their relationship, and scientists do not understand why.
In 2013, researchers observed elephants at a watering hole that was visited by several groups of elephants. However, the behavior at this watering hole differed sharply from what scientists are accustomed to observing in the wild.
While high-status females went out of their way to help other females with their babies when they got into trouble, they also tried to keep certain females from coming to the watering hole. Moreover, it is interesting that these females were no different from the others, as if they were chosen at random. High-status females went so far in their hatred that they hit them with their trunks and tossed their babies aside. This behavior was very pronounced: some females were more interested in keeping their familiar females and cubs away from the watering place than in drinking themselves. The situation got worse every day, and the researchers watched as the rejected females and their cubs grew weaker every day.
It was not at all like the family support one often sees among groups of elephants. Taking care of each other makes sense. After all, this is how the group educates the next generations. Why some elephants prefer to purposefully bully other members of their family is not clear. This may be due to concerns about population size or access to water and food, but other studies have shown that elephants are willing to share with other species.
Natural selection is unpredictable. As a result of many years of evolution, animals acquire behavioral patterns that may shock the similarity with human customs or, conversely, the lack of it.
Animals arrange funerals, experience envy, take care of a partner and shift responsibility onto the shoulders of their fellows. Below we have collected cases unusual behavior animals, but if you are interested in animals with the most bizarre appearance, we invite you to get acquainted with them in the corresponding article.
elephants
The daily rituals of this intelligent animal are surprisingly similar to our own behavior - try, for example, to watch elephants bathing in the river! But most of all, scientists were struck by their emotional attitude towards the dead members of the herd. Elephants pelt their bodies with a mixture of leaves, twigs and dirt, creating a semblance of a grave. Moreover, they often visit deceased comrades and can stand at the mound for several hours, making mournful sounds. 
Pergola birds ("bowlers")
Male bowerbirds use interesting way attracting a female. They build a nest resembling a hut and compete with each other, decorating the dwelling with multi-colored pebbles, feathers, inflorescences and even small items of human use. Scholars believe that bowerbirds have three human qualities; one of them is a sense of beauty: birds carefully group decor elements by color and sensitively combine shades with each other. 
The second truly “human” quality of bowerers is the ability to learn. It is difficult for a young individual to make a beautiful nest the first time, which would suit a capricious female in everything. Ornithologists note that inexperienced youths carefully observe the construction process of adult bower houses, analyze what they see and learn from the example.
Another characteristic feature of barbers is meanness. These birds may be jealous of more talented relatives. Often, bowerbirds wait until the owners leave the nest, and destroy all the efforts of a competitor in the fight for a woman's heart.
flatworms
These primitive invertebrates are hermaphrodites. To find out which of the two individuals will take care of the offspring, and which will carelessly float away with the flow, flatworms arrange the so-called "fencing with penises." The one who wins and hits the opponent with a sexual organ will become a father, while the loser is destined to bear offspring. Not surprisingly, such pre-mating battles can last several hours - each flatworm would rather be a "man" than a "woman". 
Cuckoos
Everyone knows that these birds throw eggs into other people's nests, trying to shift the care of children to other people's wings. The cuckoo behaves like a real spy: it selects future adoptive parents in advance, notes the time of the appearance of egg laying in their nest and, focusing on it, regulates the rate of development of its own egg, periodically placing it in cold water. When the timing is right, the cuckoo waits for the right moment and with lightning speed throws an egg into the nest of an unsuspecting couple. Newborn cuckoos behave no less selfishly: after hatching, they often throw other chicks out of the nest. 
Naked digger
Nature did not endow the naked mole rat with a cute appearance (he even won a silver place in the list of the most disgusting animals on the planet), but rewarded him with the ability to eternal youth. This rodent is able to live for more than 30 years (for comparison, it is as if a person lived to the 500th anniversary), while the state of its tissues and cardiovascular system does not change throughout life. In a word, the animal dies young. 
To give you the final touch of interest in naked mole rats, let's add that they are completely insensitive to pain, whether it be cold, deep cuts on the skin or splashes of acid. In addition, these are the only mammals that have built a system of relationships according to the eusocial principle - like bees. In the flock naked diggers there is one queen that has the right to give birth to offspring. She aggressively intimidates the rest of the females of the tribe, and those, due to the large amount of stress hormones in the body, lose their ability to reproduce.
Toad Lizards
Reptiles living mainly in Central America have developed an extremely curious mechanism of self-defense against natural enemies- coyotes. When it becomes clear that it will not be possible to escape from the predator, the lizard bravely turns to face the hunter and releases streams of blood into him from the glands in the corners of the eyes. While the taken aback coyote collects his thoughts, the lizard manages to hide. 
Adelie Penguin
These birds have one of the most touching marriage rituals in the animal world. As a sign of the seriousness of intentions, the male brings a stone to his beloved. If the female accepts a sign of attention, she sings a song to her “groom”, after which the couple retires to the nest to indulge in love pleasures.Ecology
Living things in the wild sometimes seek any way to survive. Some species of animals, insects and plants are able to adapt to almost any environmental conditions. Basically, they simply have no other choice: without adapting, they would simply die out.
Our world is constantly changing, so living beings are also forced to change, sometimes such changes may seem very strange and unexpected to us For example, deer acquire fangs, lemurs learn to fly, and ants develop hooks on their backs. Learn about rare and unusual animals with the strangest adaptations.
The strangest animals
Long-legged maned wolf
Maned wolf(lat. Chrysocyon brachyurus) belongs to the family canine just like wolves, foxes and dogs. Outwardly, this beast is very reminiscent of a fox: it has red fur, protruding ears, black limbs, but there is one nuance that immediately catches your eye: the beast has an unusual long legs , which makes it look like an African gazelle.
Despite its name, the maned wolf is not a wolf per se, he is just distant relative common wolf and occupies its own niche in the animal world, being the only representative of the genus Chrysocyon.
It is believed that the maned wolf has strange long legs because they help him survive in the meadows South Africa - an endless sea of tall grass. Due to its height, the wolf notices the approaching predator faster and takes its legs faster. The wolf's large ears are also adapted to survive in such an environment. They allow him to catch any rustle of rodents in the grass, which he mainly feeds on.
Flying Malay Woollywing
Like flying squirrel, Malayan woolly wing(lat. Galeopterus variegatus) has developed a unique mode of locomotion in the forests where it lives: it uses skin folds that stretch like membranes between the limbs. Thus, the beast soars in the air, flying from one branch to another.
Malay winged wings spend their whole lives on trees. rainforest South-East Asia. Their paws are well adapted for climbing trees, however completely unsuited for rapid movement on the ground. If the animal is on the ground, it quickly dies.
The skin membranes have a thickness of no more than a few millimeters, the body of the animal seems to inserted into a small parachute. With a jump and straightened membranes, the woolly wing can overcome about 100 meters.
giraffe gazelle
giraffe gazelle or gerenuk(lat. Litocranius walleri) is outwardly similar to other artiodactyls, however, its feature is that she can stand up on her hind legs. The animal has an unusual long neck and long thin legs, which allows him to get food from tall trees.
Unlike their distant cousins the gazelles, gerenuks do not feed on grass, but on the leaves and branches of acacias, which is enough in the African savannas. It's interesting that a large number of other species of gazelles and antelopes also live in Africa, but have a completely different diet.
Unfortunately, long limbs allow animals to easily get food, however they are very fragile and can break easily, if you run across the savannah with high speed. This is an example of how adaptations can be very one-sided: they can provide an advantage in one area of life, and disadvantages in another.
Strange animals of the world
Irrawaddy dolphin helps people
Irrawaddy dolphin(lat. Orarella brevirostris) - a species of dolphins that lives mainly along the coast and in the deltas of the rivers of Southeast Asia, especially in the Bay of Bengal near east coast India.
As a close relative of the killer whale, the Irrawaddy dolphin has adapted without the use of a special appearance, and developed special behavior. These dolphins have developed partnerships with local fishermen over time.
Dolphins drive schools of fish towards fishing nets, and in exchange they get the opportunity easy to catch helpless fish before it can be pulled ashore.
This is an incredible example of how animals manage to adapt to human influence: no other animal species can work in tandem with humans, benefiting for themselves. By the way, there were several cases when fishermen sued each other for the fact that "their" dolphins helped competitors.
Saber-toothed crested deer
Deer are generally presented to us as cute and harmless animals. They are rather timid, feed on grass and leaves, and can only cause harm if hit someone with a hoof.
Interestingly, some representatives of the deer family have fangs. crested deer(lat. Elaphodus cephalophus) from China has a strange appearance: its protruding fangs are long about 2.5 centimeters reminiscent of vampire fangs.
Like deer horns, fangs help male crested deer fight each other. They also have horns, but they are relatively small, so fangs are used, with which deer pierce the weak spots of rivals.
By the way, these deer have not only a strange appearance, but also an unexpected diet: they eat carrion, which is very unexpected for the deer family.
Unique humpback ant
It might look like an ant sitting on a beetle, but this one insect is a species of humpback Cyphonia clavata that has managed to develop such an unusual appearance.
Humpbacks are generally amazing insects that can boast the most unexpected appearance because they have to adapt to difficult conditions environment.
Cyphonia clavata managed to partially imitate the appearance native tree ant, which has sharp spikes. Thanks to this, the humpback becomes an unattractive delicacy for predators.
This insect was first discovered in 1788 in Central America by Kasper Stroll, a German entomologist.
The strangest animals in the world
Indian muntjac
This animal is from the family reindeer lives in South Asia. Muntjac boasts several amazing features that are not common to other deer. locals called these deer barking deer.
When the muntjac senses danger, it makes a strange sound that reminiscent of a short rough dog bark. This is how animals warn each other of danger. Depending on the level of threat, the sounds may vary in strength and duration. Sometimes a deer can bark for an hour.
In the Indian muntjac, as in the crested deer, there are fangs that animals use during the mating season. The horns of the muntjac are longer and have a very unusual shape.
Amazonian crowned flycatcher
Birds quite often have beautiful bright tails, which they use to luring partners in mating season. Most famous example – peacock, however, another bird exhibits similar behavior: Amazonian crowned flycatcher(lat. Onychorhynchus coronatus coronatus).
The bird is relatively small an average of 16.5 centimeters) and is found in the Amazonian jungle of South America.
In most birds beautiful appearance usually possessed by representatives of the same sex, predominantly male, but in the crowned mosquito both males and females have large and very beautiful tufts of feathers on their heads. In females, this tuft is usually yellow, while in males it is orange-red. The bird fluffs up its tuft only during the mating period, and also if a person picks it up.
Strange animals of the planet
Ants with fishing hooks
AT national park Viracha in Cambodia is home to very unusual ants. These insect species Polyrhachis bihamata from the genus polyrachis live in old hollow logs of trees in colonies, made up of millions of individuals. Ants are different unusual appearance and have hook-shaped protrusions on the back.
As you might guess, these protrusions serve protection mechanisms: they are sharp enough to protect the ant from predators. As the researchers found out, these hooks can not only pierce the skin of the beast, the ant can also clings to a predator.
For one taken ant, of course, it will not do any good, the whole colony wins, since the predator usually no longer tries to feast on succulent ants with spikes.
Ants of this species have another feature. If their colony is threatened, they unite in a large flock of thousands of insects and cling to each other with hooks. Thus, the predator simply cannot grab individual ants.
alien salamander
Discovered in tropical forests Ecuadorian salamander, which has not yet received official name, looks like something unearthly, so it is called alien salamander. As it turned out, the animal does not have lungs.
Organization Researchers "Conservation International" called the newly discovered beast "incredibly ugly." He really not particularly attractive. While little is known about the new species of salamander, it is possible that this is not the last strange animal to be found in the forests of Ecuador.
Strange animal behavior
Strange habits of sea slugs
Some sea slugs have strange mating habits: they shed their penis and then they grow a new one. View Chromodoris reticulate– soft-bodied sea shellfish, which exhibits a similar behavior that is very rare among animals.
These animals are hermaphrodites and can be played by both men and female roles during mating. They penetrate each other with male organ and exchange sperm, after which they lose their penises.
This behavior, however, does not prevent active sexual life. The new penis grows so fast that the slugs may mate again the very next day.
Scientists believe that animals have learned to shed their penises in order to save energy, but in the case of sea slugs, energy costs, on the contrary, it turns out too much, as it is necessary to grow a new organ.
living stones
Off the coast of Chile and Peru lives a strange sea creature that can skillfully disguise itself as rocks. However, if you accidentally step on such a pebble, it might start to bleed.
This is strange creature called Pyura chilensis and belongs to the class of ascidians - bag-shaped creatures. Pyura filters water while feeding thus collecting useful microorganisms. However, the most interesting feature of these creatures is their reproductive system.
Pyura is born as a male, and when it becomes an adult, it also has female genital organs, thus the animal becomes a hermaphrodite. During the mating season Pyura lays eggs and at the same time secretes sperm into sea water. That is, the eggs and sperm of the same individual can combine into a tadpole embryo.
Despite the blood red color, the blood Pyura transparent. These animals eaten, they are quite popular in Chilean restaurants.
) is a prestigious competition held in London by the Natural History Museum. Over the past 50 years, hundreds of thousands of photographs have been presented here. wildlife. Some of them were specially selected for a new book on animal behavior. Let's see something.
1. Woodpecker at work, Finland. I hollowed out a large hollow in the tree, going down about 60 cm. The woodpecker's beak is the perfect tool, it has a high-strength inner layer of bone tissue and a flexible outer layer that helps reduce vibrations. If the female likes this house, she will lay two to eight eggs here, which a pair of woodpeckers will take turns incubating. (Photo by Benjam Pöntinen | Unforgettable Behaviour):
2. Patagonian hares from the order of rodents. Up to 20 pairs live in such a hole. While children are walking with adults, almost like in a kindergarten, one of the adults is always on guard and watching for the approach of predators. It could be a fox or an eagle. If danger is detected, a signal is given, and everyone immediately descends underground. This behavior and division of duties is unique among mammals and offers a great chance of survival. (Photo by Darío Podestá | Unforgettable Behaviour):
3. Musk oxen on Victoria Island, Canada. These arctic animals fight off predators (wolves) by lining up with the babies behind them. The wolves try to put the bulls to flight in order to catch up and grab the weakest at the end of the herd, but they cannot cope with such a defense. (Photo by Eric Pierre | Unforgettable Behaviour):
