Hovering over the surface of the water a resident of the deep sea. Grand spectacle, is not it? They jump out of the water for a few meters, executing a somersault in the air and unthinkable pirouettes. At the same time, scientists can not explain why Mobule need such "flying" over the sea !?
This can only be seen in the waters of the Gulf of Mexico. After all, there live next of kin "Sea Devils" - Mobuly rays.
Mobuly belong to the family of Mantua, which owns the largest rays (giant "Sea Devils" weighing up to two tons).
Size Variation members of this genus skates great. It varies from one meter to themselves small species to five-meter width of the disc - at large Mediterranean stag, whose mass is more than a ton. Live in small flocks Mobuly in the water column. They feed on various plankton and small fish. At the time when they quietly swim fins exhibited head forward and direct sails past the prey into the mouth.
Thanks to the wing-fin rays swim fast. Besides great ability to swim, Mobuly can fly. They often jump out of the water column for a few meters, from time to time making one after another whole series of jumps. It is a pleasure to see how these wonderful animals perform many flips and pirouettes.
It remains unknown why Mobula flies over the sea. Zoologists who study the behavior of rays, divided in opinion. Some believe that the flight is part of the ritual of courtship during mating season Mobul. Others tend to believe that so stingrays get rid of parasites. Also, it is believed that the flights over the sea - is a type of hunting Mobula. Is it possible that in this way they are simply having fun.
Mobul - spreading its "wings" and float on the surface of the water the whole flock. A "sweep" of the wings, meanwhile, have reached 3.5 meters.At such moments, share experiences sailors, it seems that the sea lined with some magical carpet.
Unfortunately, these wonderful fish birds are considered an endangered species. Their number is rapidly shrinking due to industrial catch.
Generally mobula - name of the genus in the family fern, and not an individual animal, but often under this title understand exactly rays living in the water column in the open waters. All known species mobul 9:
Some species have considerable differences. For example Mobula eregoodootenkee grows only up to 1 m. In width, while Mobula mobular (another name Devil beam) to enormous 5 m. Or more. Large species prefer to live in isolation. Smaller members of the family form large flocks.Particularly impressive and fascinating look great "herd" mobul off the coast of South America.
But, despite this impressive size, about mobul little is known. It was found that the main diet of zooplankton. Adults can eat small mollusks and crustaceans.
Some species (eg devil-ray) are spiny tail, resembling a stingray barb. It is believed that he is an animal as a weapon of self-defense.
Well, let's hope that scientists eventually find the answers to these questions. In the meantime, can only admire this magnificent sight.
