Before you list (with photos) of ten prehistoric fish, which were considered extinct. Feel free to mention in the comments of those we excluded.
Mixins
According to records, Mixins have already exist more than 300 million years. These vertebrate predators, feed in the main fish, sometimes worms, dwell in relatively deep waters and reach length - 45-70 cm. Mixins are very survivors, can be very long, it costs to starve and long stay with extremely heavy wounds for a long time. The case is described when the fish, being beheaded, continued to float another 5 hours.
Alepizavr
At the ninth place in the rating of prehistoric fish, which was considered extinct spaced by "Alepizavr." Agree, he externally resembles a fish living during dinosaurs. Very little, it is known about their habitats, although they are widespread in all oceans, except the polar seas. Aleupizaur can reach lengths up to 2 meters. It is considered very voracious - to eat small fish and squid.
Aravanov - family of tropical freshwater fish found in the Amazon basin, and in some parts of Africa, Asia and Australia. Are voracious predators that feed on any small animals that can catch, including birds and battle mice (They can jump to 2 meters). Often demonstrated in public aquariums and zoos.
The sideline shark externally looks more like a strange sea snake or eels than on shark. This rare predatory Fish It dwells in the deep waters of the Atlantic and Pacific Oceans, where it is powered in the main squid and fish. Can reach a length of up to 2 meters (females larger than males). The planned shark is not dangerous for a person - most of these sharks spend their entire lives, without seeing people.
Most large view sturgeon can grow up to 6 meters long (as the most big representative White shark) and weigh up to 816 kg. Mostly keep closer to the bottom, where they feed on small animals. For a person, danger does not represent.
Arapaima
Arapaima is a tropical freshwater fish, it is considered one of the largest freshwater fish of the world - length is usually up to 2 m, but individual individuals reach 3 meters, and the weight, the largest caught aparticle amounted to 200 kilograms. Inhabitants in thick overgrown waters in South America in the Amazon River basin on the territory of Brazil, Guyana and Peru, where the main fish is powered, as well as other small animals, including birds. An interesting feature This fish is that it should float on the surface every 5-20 minutes, in order to breathe air (as well as cetacean). It is considered one of the most dangerous creatures of Amazon.
Pilorable skates
Pilorals - are under threat of extinction and are found in the tropical regions of the Atlantic, Indian and Pacific Oceans, always near the coast, sometimes swim in the line big rivers. Pilorable rocks outwardly are very similar to the pilon sharks, but compared to sharks, the rods are much larger and reach up to 7.6 meters in length. Mostly peaceful, but if the skate provoke, can become extremely aggressive and dangerous.
Missisipian Pancirnik
Missisypan Shecirnik is a kind of large predatory fish common in North and Central America. It is one of the largest freshwater fish (although sometimes it will raise into the sea): reaches 3-5 meters long and weighs up to 150 kg. This is a voracious predator that can be launched by their jaws in half the young alligator. To date, there are no confirmed, registered deaths of people, from attacking these fish.
In second place in the list of prehistoric fish, those who were considered extinct is "Senegalsky Multiple" - freshwater predatory fish, common in Africa, which is relatively small - length 50 cm. It has very poor eyesight. The polyptore is hunting the smell and attacks all fish that can swallow. Also this fish often contains in aquariums.
Coelacanth
Latimaria is the most famous of all "live fossil" and deserves to be the first in this list. These predators grow up to 2 meters and feed on fine fish, including small sharks. Dwells in deep, dark waters in the eastern and southern coast of Africa and Indonesia. For 400 million years, Latimaria has practically not changed. Are threatened with disappearance.
SAMI ancient fish Received the name Lidsichtis (Lat. Leedsichthys). These are giant bone fish living in the Jurassic period. Lidsichtisov belongs to the family of dirty dust of dust-shaped. Fish is described mainly on the basis of fossils. The first finds are dating back to 1889. They found a collector of fossils Arthur Leeds, near Peterborough (England). Then in 2003, again, not far from Career Peterborough began excavating the full skeleton of Lidsichtis. It was the first full skeleton of ancient fish. Thanks to this find, scientists were able to more accurately set fish sizes. According to their calculations, the length of the fish reached 20-24 meters. The most ancient fish on Earth was a little more than the current whale shark. This is one of the biggest bone fish in the history of our planet and lived in the tropical seas in the area of \u200b\u200bthe current Europe
Researchers believe that this fish dinosaur has disappeared simultaneously with dinosaurs. According to the assumptions of scientists, adults of this type of fish weighed about 21.5 tons. They lived about forty years. They had a pretty huge mouth. He was used as a vacuum cleaner, sucking them plankton and possibly tens of thousands of small fish, including shrimp and jellyfish. He filtered food with the help of gill stamens. Such as, 
modern whale sharks. I have such huge sizes, Lidsichtis could not be a predator. Even the huge sizes of these fish did not protect them from predators. They were easy prey. Even the smallest predatory residents of the ancient oceans could, without much difficulty, snatch a piece of meat from these fish. But almost no one could kill them. Therefore, predators were waiting for several days until the fish dinosaur died, while it was continued to bite the flesh. Fish eaten practically alive. According to scientists from Bristol University, Lidsichtis is the most ancient fish on earth. A special type of such fish lived on our planet about 160 million years ago. The skeleton of fish is striking all with their dimensions. The length of the last detected fossil reaches 16 meters, well, alleged lidsichtis weight is equal to two 2-storey buses that drive 
in London or three African elephants.Professor Jeff Liston, during the interview with Mail Online, said that Lidsichtis skeletons were poorly preserved. Generally discovered individual fragments. For this reason, preliminary estimates of the size and description of this type of fish are unreasonable. But all, the existence of such huge fish plays an important role. After all, this explains a lot about changes in the population of plankton, inhabitants in the Jurassic period in the oceans of our ancient planet.
Recall that today the longest bone fish in the world is the Selrian King. The body's length of this fish can be up to seventeen meters.
Who they are and from
Shark is one of the most ancient inhabitants of the World Ocean. The first sharks appeared in the Paleozoic Era, 350-320 million years ago, and similar modern - 150 million years. Together with the rods, they still have the biological name "Celahia", and belong to the group cartilage fish. Unlike most fish, there is absolutely no bone tissue in their skeleton, but the body is covered with scales, the fabric of which is identical to the tooth tissue. These and other features allow them to be considered by their primitive existing fish. However - for millions of years, they adapted to life perfectly. Again, the features of the teeth, movement, nervous system And the senses are completely equalized by the level of organization with the most progressive bony fish, and in places and give advantages.
About 350 types of sharks are known. Most relate to the so-called real predators, individual species (which is interesting - the largest), such as gigantic, whale and more, feed on plankton.
They are us ...
The bad reputation shark is old, as well as familiar with them. There are still no certainty in this matter. Sometimes children, and scuba wheels bathe and swim near the shark - and nothing terrible does not happen. And another time, sharks grab the swimsters on crowded beaches, in small water, where a person is on the belt and wherever never had anything like that.
Rich prey brought sharks last two world War. As a result, even the staff officers understood how dangerous sharks are for soldiers, sailors and pilots that endure disaster in the tropics. And at the beginning of the war, "Inserting for the survivors in the shipwrew", published in the United States, was written about the shark as follows: "Slow, cowardly and can be frightened by slaps on the water" ... Probably, with such recommendations can be faced now. But what they led to, on the example of the aforementioned sailors:
"NOVA-CHOTITION's transport has been sulking off the coast of Southeast Africa, a thousand people died. There were many corpses in rescue vests - and all the bodies were without legs. "...
On the this moment It is believed that the main reasons for attacking sharks three:
- Blood that fell into the water.
- Wounded or frightening fish.
- Ineptly flusted swimmer and fear discovered by him before shark.
Statistics showed: In most cases, the sharks attack floating, walking through the water in it, when they have legs in water, and head and shoulders over it. Therefore, for scubaers, the most dangerous moment when meeting with shark - exit water and appearance on the surface.
If you exclude shipwrecks, then two thirds of all registered shark attacks are made in shallow water, at a depth of no more than one and a half meters, in a hundred and near that meters from the coast, mainly in the tropics and subtropics, where the water temperature is at least 18 degrees. But here there are a lot of exceptions: there were cases of death from sharks and in very cool water (12 degrees). But in general, it was established: when the water is colder than 15 degrees, the most dangerous sharks lose their appetite, sluggish, and dongy "game", fortunately for her, they no longer attract.
... and we are them
The possibilities of using shark like fishing fish are very diverse. The meat of most species of these fish is edible, nutritionally and has long been used in the food in many countries of Europe and Asia. The liver of sharks is greater value - its mass in a number of species ranges from 5 to 30% total mass Body. Akuly Liver contains 40-70% fat rich in vitamin A. at the end of the 60s. In the liver, some sharks discovered a hillone-like substance that significantly increased the body's resistance to oncological diseases. The shark and in Russia - in 1862, 5 thousand pounds of the liver of polar shark were produced in the Kola lip of the Russian Poms.
From the cartilaginous skeleton, the shark has long been the gelatin and glue.
Skin sharks (shagreen) is used for a wide variety of purposes - haberdashery goods and shoes are made of it, used as an abrasive material when grinding the valuable wood, as well as when processing felt. Akuly The skin is distinguished by extraordinary tensile strength, withsting an effort to 500 kg / cm 2, while the oxen is only 300 kg / cm 2.
No less valuable part of the Body Shark are its fins. Usually their mass is from 1.7 to 4% of the total fish weight. All fins longer than 15 cm long, with the exception of the tail, treated accordingly, are used to prepare a delicacious soup. Varna and purified fins are preserved, and the canned foods are also used to prepare soups. The main consumer of the fins and the aforementioned soup is China than and caused a noticeable reduction in the number of sharks in recent years.
When the shark fishery uses almost all fish guns that currently exist now - their choice depends on species composition Shark, Relief of the bottom in the area of \u200b\u200bthe fishery and other factors. Large sharks catch on the tier, rapidly hit Garpun, and small species are caught in trawls and networks.
Recently, there is a significant decrease in the catch of Shark - if in 1967-68. They were produced in all oceans about 340 thousand tons, by the end of the 90s. This value has decreased more than twice. This is due, first of all, with a decrease in the number of sharks as a result of their active fishery in previous years. Considering slow temp Reproduction of sharks, many countries have begun to regulate their fishery.
Katran - almost no exotic
Finally, purely pragmatic information. Recently, a number of travel agencies of the Black Sea coast of the Caucasus are called shark fishing among offers! The hunt for the Black Sea Aclaus (Katrana) passes in the territorial waters of Russia, along the Black Sea coast from Cape Panagia to Cape IDOKABAS on removal from the shore of 12 nautical miles. The recommended season - from the end of May until the beginning of November, the peak falls on August-September. Liva time in the open sea 24 hours. The cathrane is a prehelovoid body sometimes up to 2 meters in length, ends with a vigorous tail. Slow-like, cross, front, in front of two dorsal fins are sharp covered with a poisonous spike mucus. Brown, with white spots on the sides of the skin is covered with rhombid scales with sharp spikes. Beluto white. There is no swimming bubble. Sharks are heavier than water, and therefore movement is their lifelong lot. It is kept in water while they move or at least move the tail, otherwise they are drown. Yes, and the high speed of movement is also a significant factor of their well-being. Only on the go, at sharks, a sufficient amount of oxygen enters the body through the gills. Otherwise, they may suffocate.
The amateur fishing of the Black Sea shark is gradually becoming increasingly popular. Catch it from a small vessel standing by anchor or in drift. And in that and in another case, they use the bait of finely chopped fish - it is necessary that the odorless trail spread by the privada was continuous.
Catch, as a rule, at once, several rods of class 15-24 kg equipped with powerful multiplier coils. The cost of such entertainment is within $ 1000.

We all know about the school that many ancient animals who inhabited the planet once long have been extinct. But do you know that animals who have seen dinosaurs have been living on Earth now. And there are animals that exist longer than trees from which these dinosaurs ate leaves. At the same time, many of these ancient fauna representatives practically did not change over millions of years of their existence. Who are these old-timers on our land and that they are so special about them?
1. Medusa
The first place in our "rating" is rightfully occupied by jellyfish. Scientists believe that jellyfish appeared on Earth about 600 million years ago.SAMI big Medusawhich man caught, had 2.3 meters in diameter. Medusa live for a long time, about a year, because they are a delicacy for fish. Scientists break their heads over how jellyfish perceive nerve impulses from the organs of vision, because they have no brain.
2. Nautilus
Nautilusi live on Earth more than 500 million years. These are congorative clams. Females and males are characterized by sizes. Nautilus shell is divided into cameras. Mollusk himself lives in the largest chamber, and the rest of the compartments, filling or pumping the biogas, uses as a float for immersion to depth.
3. Snacks
These maritime arthropods are rightfully considered alive fossils, because they live on Earth more than 450 million years. To imagine how long, I will say that the swords of older trees.
They did not have difficulty survive all the well-known global catastrophes, practically without changing outwardly. Sneakers can rightly be called animals "blue blood". Their blood, in contrast to ours, has a blue color, because it is saturated with copper, and not iron, like human.
The blood of swords has amazing properties - when it reacts with microbes, the clots are formed. It is in this way that swords make a barrier from microbes. From the blood of swords, they make a reagent and with its help check drugs for purity.
4. Neopilines
Neopilina - mollusk that lives in about 400 million years. He has not changed in appearance. Inhabited nonopilines at high depths in the oceans.5. Lathemeria
Lathemeria is a modern fossil animal that appeared on our planet about 400 million years ago. For the entire period of its existence, it has practically not changed. At the moment, the latimarius remains on the verge of extinction, so the catch of these fish are strictly prohibited.
6. Akula
Sharks exist on Earth more than 400 million years. Sharks are very interesting animals. People explore them for many years and do not cease to be surprised by their uniqueness.For example, the teeth have sharks all life, the most big sharks May reach 18 meters long. The shark is beautiful scent - they feel the smell of blood at a distance of hundreds of meters. Sharks practically do not feel pain, because their body produces a certain "opium", which dulls pain.
Sharks are stunningly adapted. For example, if oxygen is not enough, they can "disable" part of the brain and consume less energy. Sharks can also adjust the salinity of water, producing special means. A shark vision is several times better than cats. In dirty water, they see up to 15 meters away. 
7. Tarakany
These are real old-timers on Earth. Scientists argue that cockroaches inhabit planet more than 340 million years. They are hardy, unpretentious and fast - this particularly helped them survive on the most rapid periods of history on earth.Cockroaches can live for some time without head - after all, they breathe the cells of the body. They are excellent runners. Some cockroaches per second run around 75 cm. This is a very good result regarding their growth. And about their incredible endurance indicates the fact that they are withstanding radiation radiation almost 13 times more than a person.
Cockroaches can live without getting about a month, without water - a week. Their female retains the seed of the male for some time and can exacerbate themselves.
8. Crocodiles
Crocodiles appeared on Earth about 250 million years ago. Surprisingly, first the crocodiles lived on land, but then they liked a significant part of their time to spend in water.Crocodiles amazing animals. It seems that they do nothing just like that. To facilitate digestion of food, crocodiles swallow stones. It also helps them dive into depth.
In the blood of the crocodile there is a natural antibiotic, which helps them not sick. The average duration of their life is 50 years old, but some individuals can live and up to 100 years. Crocodiles are not leaving for training, and they can be considered the most dangerous animals on the planet.
9. Splash
Schedule appeared on Earth during the dinosaurs period of about 230 million years ago. They live almost all over the world, except Antarctica.Surprisingly, the shield did not change in appearance, only steel than the size. The biggest ships are found in size of 11 cm, the smallest - 2 cm. If shield comes hunger, there are cannibalism among them.
10. Cherepakhi
The turtles inhabited the earth about 220 million years ago. From their ancient ancestors, the turtles differ in that they have no teeth, and they learned to hide their heads. Turtles can be considered long-livers. They live up to 100 years. They see perfectly, hear, have a thin scent. Turtles remember human faces.If the temperature is in the nest, where the female postponed the eggs high, the females will cause, if low - only males.
11. Gatteria
Gatteria - Reptile, which appeared on Earth more than 220 million years ago. Now Gatteria live in New Zealand.Gatter looks like Iguanu or lizard. But this is only similarity. Gatteria established a separate detachment - beakhead. This animal has a "third eye" on the back of the head. At Gatteria, the metabolic processes slow down, so they grow very slowly, but it is easily waiting for up to 100 years.
12. Spiders
Spiders live on Earth more than 165 million years. The most ancient web was found in amber. Her age becomes 100 million years old. A spider female can postpone several thousand eggs - this is one of the factors that helped them live to the present day. Spiders have no bones, their soft cloth covers a solid exoskeleton.We could not do artificially in any laboratory. And those spiders that were sent to space, hung three-dimensional cobwebs.
It is known that some spiders can live and up to 30 years. The largest famous spider It has a length of almost 30 cm, and the smallest - half a millionth.
13. Ants
Ants are amazing animals. They believe that they live on our planet more than 130 million years, while practically without changing their appearance.Ants are very clever, strong and organized animals. We can say that they have their own civilization. They have order in everything - they are divided into three castes, each of which is engaged in their own business.
Ants are very well adapting to circumstances. Their population is the biggest on Earth. To imagine how much there are many of them, imagine that about one inhabit of the planet is approximately a million ants. Muranes are also long-livers. Sometimes uterus can live to 20 years! And they are stunningly intelligent - ants can train their fellow food.
14. Utkeonos
Wallowders live on Earth more than 110 million years. Scientists suggest that at first these animals lived in South America, but then they got to Australia. In the 18th century, the skirt of Rockosov was first seen in Europe and counted ... fake.The walls are wonderful swimmers, they easily minide meals from the river bottom with the help of beak. Almost 10 hours a day, the walls are carried out under water.
Clockproofs failed to multiply in captivity, and in wildlife Today they remain quite small. Therefore, animals are listed in the International Red Book.
15. Echidna
The echidna can be called the same-standing of cliffs, because it inhabits the land of 110 million years.Echids are like hedgehogs. They boldly protect their territory, but in danger, they burn into the ground, leaving the needles on the surface only.
Echidna has no sweat glands. In the heat they move little, they can fall into the hibernation in the cold, thus adjusting their heat exchange. Echids are long-livers. In nature, they live up to 16 years, and in zoos can live and up to 45 years.
Interestingly, whether a person is staring on Earth for so long?
Today, many terrible creatures live in the oceans - this is a glass sharks, and huge squids, and mysterious deep-sea fish. But still, the creatures found in the depths of the water in their parameters did not come close to those gigantic creatures that lived in the seas of the past.
Then it was possible to meet huge marine lizards, monsters-sharks and even dangerous killers. If today maritime livery seems to us mainly as a source of food, then in those days the person would have become. Tell me below 10 of the most terrible monsters that lived in the oceans in prehistoric times.
This creature is obviously the most famous in the list. The name itself is translated as a "big tooth". Many will hardly even imagine the fossil shark size with a school bus. Sproves popular science sources, like the Discovery channel, which, using computer technologies, frustrated monster. Shark was 22 meters long, and weighed about 50 tons. It was one of the largest predators for the entire existence of the Earth. The strength of the bite on 1 sq. Cm was up to 30 tons. Although it seems that such a creature lived in the age of dinosaurs, Meghalodonov lived on the planet 25-1.5 million years ago. Consequently, gigantic sharks burned down with the latest dinosaurs of about 40 million years. By the way, it is quite possible that Meghalodonov managed to meet with the first ancestors of people. Meghalodonov lived in the warm oceans, hunting for whales. But after the start of the glacial period, the flow of the ocean changed in Pliocene. In the new conditions, gigantic predators could no longer exist. Today, white sharks are considered their closest relatives.
These animals were typical Pliosevors, representatives of the Jurassic period. For the first time they were described on the basis of the sole found tooth in France in 1873. At the end of the same century, a skeleton was found. These were creatures long from 6 to 25 meters, with a large narrow head. Scientists believe that she could reach 4 meters long! Huge teeth reached half a meter. Floating the creature with the help of huge flip, climbing the surface behind the air. It could dive for a long time and deeply. Scientists on the basis of the remains simulated the body of the loperevrod. It turned out that he was not so fast as very flexible. The inhabitant of the sea was playing fast jerks, attacking the prey. There is no doubt that the liovironment were nobbing - such dimensions simply did not give them the opportunity to handle the shore to lay eggs.
Despite its unusual viewThis creature is not at all reptiles. This is a whale, and is not the most terrible on our list. Basilosaurs - the predatory ancestors of the current whales. In length, they reached 21 meters, and lived on the planet 45-36 million years ago. In those days, basilosaurs inhabited all the warm sea of \u200b\u200bthe planet, being one of the biggest predators. Whale is actually more like giant snakeSince he had a long winding body. His victims were major creatures, including Rudezhone. Today, only a fantasy about swimming in the ocean, where the creature of alligator-snake-whale lives, can be for a long time to kill interest in water procedures. The physical data of Basilosaurs suggest that they were deprived of the cognitive abilities of modern whales. They did not possess echolocation, practically not immersing at great depths. They also had no social skills, whales were single. As a result, the monster was quite primitive and could not pursue his sacrifice if she was chosen on land.
The name of this creature sounds not too scary. Meanwhile, it was one of the largest artiforms for all time. Raccorpions lived 460-250 million years ago, reaching a length of 2.5 meters. Only their ticks were up to half a meter. In those days, the oxygen level in the atmosphere was higher, which was the reason for the appearance of giant cockroaches, scorpions. Scorpio remained sea \u200b\u200binhabitantAlthough many of his relatives at that time began to master and land. These creatures extinct before dinosaurs, now it is not clear even whether they were really poisonous. However, the structure of their tail resembles the structure of the same part of the body in scorpions, which makes it possible to assume the attacking function of the tail.
These animals belong to waterproof dinosaurs. They lived at the boundaries of water and sushi. Majorovs could jump into the water, fleeing against predators. In length, these creatures reached 7-9 meters, their weight was about 2-3 tons. Majorovas lived 80-73 million years ago. Flat wide tough beak animals plucked vegetation or collected algae. The Neck of the Majorum consists of a variety of vertebrae, which implies its flexibility. On the skull was a small comb. The hind legs were strong, withsting body weight. Michaeling could defend themselves with their powerful tail. Animals set off eggs, kids about half a meter appeared from eggs. Majorovas lived in herds, as evidenced by a large number of skeletons found next to each other.
This creature can be called a real carnivorous tank. The ferocious predator reached 10 meters long, and his body was covered with plates that performed the role of armor. There is an explanation - Dunkleostei hunted both in his fellow and on other predators. Bones in the usual understanding did not have, their role was performed by sharp bony ridges, like a turtle. But the strength of the bite at the same time was 8,000 pounds per square inch, which is comparable to the crocodile bite. The predator skull was equipped with a powerful muscles, it made it possible to tighten food inside as a vacuum cleaner, for a split second. The advantage of dunkleos was that the jaws were powerful and fast. Hunter at high speed opened his deadly mouth, capturing prey with a huge force. Almost none of the inhabitants of the ocean at that time had a chance to escape. Dunks - the most dangerous monster in the ocean at that time. These carciro fish lived 415-360 million years ago.
This pliosewood is one of the most famous public and the largest in this family. For a long time Disputes were told about the true sizes of this inhabitant of depths. As a result, scientists have proven that the Kronosaurus reached a length of 10 meters. At the same time, only the skull reached 3 meters. In a massive mouth, the teeth are abundantly located, up to 11 inches long. The Kronozavr became famous as "the king of the ancient seas" and even "T-Rex Ocean". It is no coincidence that the name of the predator was given in honor of the Kronos, the king of Greek titans. Crowded Kronosaur in the Southern Polar Seas, which could be very cold in those days. For the first time, the remains of the animal were found in Australia. The animal flippers are like a turtle. Perhaps the Kronozavra crawled to the shore to lay out the eggs. You can be sure that no one has digging their nests, so as not to angry the Terrible Predator. Crichelov lived about 120-100 million years ago.
The length of these sharks reached 9-12 meters. At the same time, their uniqueness consists in possessing a dental spiral on the lower jaw. This formation could reach 90 centimeters in diameter. The mixing of the circular saw and the shark was a real sea horror. The teeth of the animal were toothed, which implies her carnival. It is not clear only where the spiral was located - in front of the mouth, or deeper. The last option implies a different power mode, softer (jellyfish). The body structure remains unknown. But the fact that Helixopon was a rather smart creature, no doubt. The predator was able to survive after a triad extinction, possibly due to its habitat in the deep layers of the ocean.
This ancient predator was among the average between the current crowd and ordinary coushlot. In 2008, they found the remains of China, which hunted on other whales. His teeth were the largest for food among all animals. Although the tissue of the elephant and is larger, but they are not intended for this. The diameter of the teeth was 12 centimeters, and their length is 36. The body of the ancient coushlot was in length of up to 17.5 meters. Interestingly, Cachelot lived about 13 million years ago, and therefore competed in the ocean for prey with Meghalodon. The head of predatory whale in length reached 3 meters, there are signs that there were organs of echolocation, as well as in modern teeth whales. Consequently, in conditions of muddy water, Leviafan could effectively navigate. The animal was named after Leviafan, the biblical sea monster, as well as in honor of Herman Melville, the author of the novel "Mobi Dick" (in it just attended the giant couch).
In the diameter, this fish reached 5 meters, besides, she is poisonous. Skat is quite strong to drag on yourself a boat with people. In this case we are talking About prehistoric super fish, the descendants of which is still hiding in the fresh and saltwaters of the Mekong River and in the north of Australia. Here, no one surprise two-meter skates with weight in three centners. Fishes are already several million years old, the structure of their body allowed them to stay alive. Giant fish were able to survive even the ice age. For their sizes and an unusual view of the skate, the name "Sea Devil" was called. In the front of the body there are small eyes, behind them - the gills and the torn mouth. Interesting, but the skin around the mouth and the nose is a sensitive zone that allows the skate to catch electric and magnetic fields other living beings. It makes it easier to find food. A freshwater predator has a terrible weapon - at once 2 powerful and sharp spikes on the tail. The greatest of them fulfills the role of harpoon, it is easy to sacrifice and keeping inside at the expense of jar. The blow strength is so great that even the bottom of the boat will not stand before him. The length of the spike reaches 38 centimeters. The second spike is smaller, it is designed to injected poison. This substance is deadly for a person. Skat feeds on fish, molluscs and invertebrates. Female skate knitles.
