Flora and fauna
Over the past Millennium has developed this unique shape of the Black sea. This is the most fresh sea, with the lowest content of salt in sea water, the gentle sea-to-person around the globe!
The black sea is the most Northern subtropics in the world, awesome beauty of the southern nature. It walks under the shade of palm and eucalyptus trees. It’s the heady aroma of blooming magnolias and meadow grasses. The Mediterranean sea brought the most modern inhabitants of the Black sea. The few remaining survivors of the disaster relict freshwater species, including the famous Azov-black sea sturgeon, took refuge in the river deltas of the black sea region.
The flora of the Black sea
The flora of the Black sea includes 270 species of multicellular green, brown, red benthic algae (Cystoseira, Phyllophora, zoster, kladofora, Ulva, enteromorpha, etc.).
In the composition of phytoplankton in the Black sea — not less than six hundred species. Among them, dinoflagellates — loricate flagellates (prorocentrum micans, ceratium furca, small scripsiella Scrippsiella trochoidea, etc.), dinoflagellates (dinophysis, protoperidinium, alexandrium), various diatoms, etc.
The fauna of 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 videodnevnik, 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.

You go to the Black sea. Do you know what sea monsters eat? The black sea is very friendly and perfectly safe for humans. There are no scary sharks, poisonous sea snakes, Barracuda and other horrible monsters. Besides, in the sea, as on earth, just for something to do on man, no one ever attacks. And if there is in the Black sea inhabitants that can cause you a little trouble, do not grab their hands and pull the tail… kornerot jellyfish Is the largest jellyfish of the Black sea, the diameter of the dome can exceed 40cm. It is easily recognized by this fleshy, bell-like dome and a heavy beard of the mouth of the blades underneath. Lace on the blades of Camerota are poisonous stinging cells that can burn the skin, like hot water or nettles. Probably why the jellyfish has three more Russian names: sea nettles, gigalo, Zhuchka. When you see it follow the simple advice: don’t touch comerota, go around, “oblivate”. And do not touch even dead, or at least wash your hands afterwards. Otherwise, RUB their eyes and accidentally get burned. Kornerot helps to survive in the sea for juvenile fish that are hiding under his hood from the predators have feasted on those tasty little thing, but I’m afraid of stinging cells jellyfish. Himself kornerot feeds exclusively on plankton, but kornerot in the sea doesn’t eat anybody. Scientists say jellyfish to the category “food stubs”. (Although in Japan,Korea and China comerota eat: this is “crystal” meat can be boiled, fried and even salt). And here another interesting detail concerning jellyfish. It turns out that they have eyes. And the same kornerot, presumably, sees us well, although it is difficult to say in what form. However, again: jellyfish, even the most venomous itself to attack the person never will be… the Dragon is Not aggressive to man and other poisonous inhabitant of the Black sea – dragon. It is a demersal fish with a large angular head, bulging eyes and a huge, greedy mouth. Dragon usually buries itself in sand or silt, and there awaits its prey. In this case, the sand sticks out his dorsal fin, five rays of which the poisoned spines. Spikes and toxic slime from dragon are not for attack but for defense. However, accidentally stepped on has buried in the sand of a dragon, can significantly be affected: a shot of this small black sea fish is equivalent to the bite of poisonous snakes. But don’t be afraid to step on the dragon – the event is unlikely, usually the fish manages to get away from the approaching person. Much more likely to get injured dragon, the fishermen who caught it on bait. In this case it is better not to try to remove the dragon from the hook alive prick. And the sting of this fish is dangerous even after her death, therefore, to start cooking meals from dragon, remove with scissors its dangerous spikes. In taste same qualities of the sea dragon is just gorgeous, he’s a good as a holiday and in the ear. Continue reading
