frilled shark - fish of the Cretaceous period, inexplicably lived to this day.It lives in the oceans except the Arctic, deep water, in the bottom layer.On the surface practically does not rise, because extremely rare.Cases catch this shark off the coast of Europe and North Africa, South America, California and Japan.
name for this fish had an unusual fold of fibers coated with a first pair of gill openings.They are joined on the ventral side and remind cape or collar.Her body was long (about 2 m), snake-like, brown tones.Females are slightly longer than the males.Eyes oval, without nictitating membrane.Prehistoric shark has a cartilaginous spine, the vertebrae are not divided into.The caudal fin is represented by only a single blade.Large fins located next to each other near the tail.
frilled shark has an outstanding oral cavity, located on the end of the snout, but not on the bottom, like a modern fish.Teeth vaguely resemble the crown, five-pointed, hook.Location teeth unusual: small front and large rear, which is not typical for the Sharks.The total number of teeth - about three hundred, all of which are very sharp.Jaws long, can be stretched to swallow prey, not raskusyvaya.Hunting, shark's body bends sharply and rushes to the prey, like a snake.
Prehistoric shark hardly been studied because of its deep-sea habitat area.We know only a few cases where such items have been caught alive.The last time this happened in January 2007.Not far from the Japanese fisherman boat popped something they previously unseen.The fisherman told about what they saw park administration "Avasima" (island of Honshu, the city of Shizuoka).The Japanese are not only caught, but also photographed this predator.Fish has a length of 1.6 m, he wriggled like an eel.It counted 300 teeth, 25 rows.Frilled shark was placed in a pool with sea water, but died a few hours later.Most likely, disease and forced her to rise from the depths of the ocean.This is only conjecture.
frilled shark fishing is not important, as is extremely rare.And every meeting with her man - an event (for the person, of course).Most of these "visits" are random.People set up a network for benthic shrimp agile.And pulling out the network, see only the rags, so Japanese fishermen consider them pests.
Recently, a number of meetings with people plaschenostsev increased.But scientists are inclined to believe that this is due to the increase in water temperature of the oceans, and not because of the increase in the number of predators.At the bottom of the ocean lacks air and preserved prehistoric living creatures are forced to look for a new habitat.So, in 2012, Murmansk fishermen pulled a "historic" the catch.In the waters of the Barents Sea they caught the oldest representative of the sharks.
not disappeared and did not undergo significant changes, frilled shark might regain power over the sea depths, becoming its rightful inhabitants.
