What sharks live in the Black sea?
The fauna of the Black sea is markedly poorer than the Mediterranean sea. In the Black sea is home to 2.5 million species of animals (including 500 single-celled species, 160 species of vertebrates — fish, mammals, 500 species of crustaceans, 200 species of mollusks, and the rest — invertebrates of different species). for comparison, in the Mediterranean — about 9 thousand species.
Among the main reasons for the relative poverty of fauna of the Black sea: a wide range of water salinities, moderately cold water, the presence of hydrogen sulfide at high depths. In this regard, the Black sea is suitable for habitation fairly undemanding species, at all stages of development which do not require great depths.
At the bottom of the Black sea inhabited by mussels, oysters, pecten, and the mollusc-predator Rapana included with vehicles from the Far East. In the crevices of the coastal cliffs and among the rocks is home to many crabs, there are shrimps, there are various kinds of jellyfish (the most common are Aurelia and kornerot). anemones, sponges.
Fish of the black sea:
Sea-dog peacock – male – Salaria pavo of fish species in the Black sea, various species of gobies (the goby-Golovach, bull-whip, round goby, the goby martovich, goby Amur sleeper). the Azov anchovy, black sea anchovy (anchovy). shark-spiny dogfish, flatfish-Glossa, a mullet of five species, lofar, hake(hake). sea ruff, barbula (common black sea mullet). haddock, mackerel, horse mackerel, black sea-Azov sea herring, black sea and Azov kilka, etc. Meet sturgeon (Beluga, black sea and Azov sturgeon) .
Among the dangerous fishes of the Black sea — sea dragon (the most dangerous — poisonous spines of the dorsal fin and Gill covers). and noticeable black sea Scorpion fish, sting ray (sea cat) with poisonous spines on the tail.
The only shark inhabiting the Black sea is a spiny shark (spiny dogfish) — rarely grow over one meter in length, is afraid of people and rarely comes to shore, holding in the cold water layers at depth. However, spiny dogfish is quite valuable fishing trophy (it is believed that the fat of the liver of this shark has healing properties) and can be dangerous for the fisherman: dorsal fins Katran provided with large poisonous spikes.
The Black sea lives in the sea Fox skate Raja clavata is a large, sometimes up to one and a half meters from nose to tail, it is harmless to humans – unless, of course, not to try to grab it by the tail, covered with long, sharp spines; and the slope hvostokol, sea cat, up to 70 cm in length. They live on the bottom, at the bottom of the find and the food – clams, crabs; therefore the mouth they shifted under a flat head, and eyes and spiracles – Gill slits are on top. Stingrays swim by waving wide body planes like wings and tail fin them away, leaving just the stem is the tail. Hvostokol uses it as a weapon. On his tail is a thorn, or rather the true sword – to 20 centimeters in length. Its edges are very sharp, and besides, serrated along the blade, the bottom side – groove, which can see the dark venom of poisonous glands on the tail. If lying hurt at the bottom of the rays, he hit the tail as a whip; however, he ottapalam their spines and can inflict deep chopped wound. The wound from the blow of the rays, is treated, like any other.
