Some inhabitants of the underwater world are familiar to us, others we ate, and the existence of the third, not all even know.There are some species of fish, the existence of which we are not even aware.They are completely different: huge and tiny, and not very dangerous, with bizarre forms and strange names.In this article you will learn that there is, for example, a fish with human teeth.Its name probably is not known to everyone.They live in the underwater depths of many countries fish for them, too, we'll talk.Let's start the journey into a fascinating and exotic world of fish.
Paku
This is the most that neither is a real fish with human teeth.Pak is a freshwater denizen of many rivers in South America.It is found in the basins of the Orinoco and the Amazon.And I got to Papua New Guinea, where it began to breed artificially to raise to a higher level of the fishing industry.Fish with human teeth belong to the same genus as the piranha (Serrasalminae), though their preferences and habits differ.Piranha is a carnivorous species, but pacu eats everything, prefers vegetation.
fish with human teeth: why is it called so?
The most important difference from the pacu piranha - is the structure of the teeth.Piranha, as we know, the owner of sharp teeth, which many compare with a razor.But the fish with human teeth has a completely different structure of the jaw, because it's called.If you look into her mouth, then you can really scared and terrified.Her teeth are square and straight, they are very similar to human.Fish use them mainly for crushing fruits and nuts, but can eat and invertebrates.It was her desire for nuts once deprived of the genitals of two fishermen in Papua New Guinea.As you can see, even pack and not a predator such as the piranha, the power of its jaws can still cause irreparable harm.And here in the United States fish it is legal and anyone can buy it and put it in an aquarium.Here are just some reason people do not take into account that pacu can grow up to a meter and weigh about 30 kg.So then the owners just let her into the nearest body of water.This may explain the occurrence of fish in Denmark, England.Some sources report that the puck has been, even in Russia.
lionfish
Continuing to talk about any unusual fish of the world there, we can not lose sight of this lovely creation.Lionfish mostly still is among the corals, but sometimes swims from one place to another.People's attention and many aquatic species it attracts unusual coloring, dorsal and pectoral fins that resemble a large fan.However, striking appearance hides sharp needles that produce the poison.Fish had not the first attack on the person, but if he accidentally stepped on it or touches, then all of a single injection has deteriorated overall health.And after a few injections a person is not able to swim to shore alone, he will need help.
chlamydoselachus
call this predator so because of the formation of brown on the body that looks like a cape.And thanks to the large number of folds in the skin it is also referred to as corrugated shark.Scientists believe that such formations on the skin are the reserve volume of the body to accommodate large production in the stomach.Because of the curved teeth into this inhabitant of water is unable to split food, so swallow their prey whole.Here will be useful and folds in the skin that can be stretched.You can see sharks in every ocean, not only in the Arctic.
Fish drop
Some fish are really able to hit their appearance.Fish-drop is one of them.She looks so unattractive that it is among the most fearsome fish available on the planet.They live off the coast of Tasmania and Australia, and at the moment there is a threat of extinction.The body of this ugly fish is composed of a gelatinous mass, density less than water.She has absolutely no muscle, but it does not prevent her lazy to open the jaws and swallow everything that swims in front of her (if it is edible).
largemouth
inhabits this unusual specimen in the Atlantic, Pacific, Indian Ocean.Body largemouth narrow and long (up to 1 meter).A fall has gigantic proportions (third part of the entire length of the body), but still can be stretched.This unusual inhabitant of the oceans no scales, fins, swim bladder and the normal skeleton.The subtle body to the tail turns into a thread at the end of which there is a luminous body.Due to the presence of a light skeleton of cartilage and bones of the deformed fish is very easy, it is very tiny eyes and a small skull.The size of the jaws allows largemouth swallow prey that is greater than itself in size.
Meshkoglot
Another inhabitant of the deep-called black eater.This fish grows no more than 30 cm in length, and named it so because of the ability to absorb the entire production, which in size several times larger than herself.For example, it can easily swallow prey that is 4 times longer and 10 times heavier than most meshkoglota!Jaws has a very large fangs and help keep the victim until the fish pushes it into his stomach.When the food begins to decompose in the stomach, it produces a lot of gas, which is why fish unwittingly rises to the surface.We know about these inhabitants is very small, as to observe their way of life in their natural environment is simply impossible.
Makropinna smallmouth
You can not see the fish and not to scream with fright and surprise at the same time.Why is that?Because she has a clear head!Bochkoglaz (second name) can easily monitor the production of their head through a tubular eyes.Open individual was only in 1939.In a typical environment for her, she fixed, and if it decides to move, it does it in a horizontal position and very slow.Previously, it was completely unclear how the eyes of the fish, because her mouth right over there olfactory organs and eyes are located right inside her surprisingly clear head, and they just look up.In 2009, scientists finally figured out that makropinny extremely unusual structure of the eye muscles.It turns out that fish eyes are usually located in an upright position, and if there is a need to look ahead, it moves it horizontally!Once this happens, she can see your mouth and grab prey!
Angler
This is a real deep monster.It is called not only to anglers, but also a fish-devil.This fish has a black bare skin, spherical shape of the body, and the female is a "rod."This predator hunts through a special process at the back - in the evolution of one portion of the dorsal fin separated from the others, and at its end there was a transparent bag, in which the bacteria live.What is most interesting, the angler can make these bacteria are highlighted!He governs it by narrowing or dilating blood vessels.The female can grow up to 65 cm, and male - just to 15-45 mm!When the male end puberty, it is attached to the female sharp teeth (usually the side).Soon he heals her tongue and lips, and his teeth, intestines, eyes are reduced in such a way that it becomes an appendage, lost independence.
Conclusion In this article you learned, what are the unusual fish (photo shown above).It does not matter, they are a danger to human or not, they should not be afraid.The main thing - to have the information and know what each individual can do.
