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.

Polychaete worms (polychaetes, a type of round worms) usually occur in the coastal zone. Buried in the sand, they expect the tide to lean out from his hiding place. These are pushily – the inhabitants of the sandy shallows. But there is deep-sea polychaetes, such as Nereid pelagic, living in the soft mud in the depths of the White sea.
“Pelagic” is called the organisms living in the pelagic – in the water or on its surface. Why is the bottom dweller of the Nereid called pelagic? It turns out that once a year, in summer, long Arctic day, all Nereids float to the surface to spawn. It is unclear how the worms managed to simultaneously leave their homes and that is their signal to the ascent. Spawning Nereids light for fish and marine birds – “time to eat”. Caviar Nereids eating not only animals. Fried eggs this large worm, similar in flavor to fried, is a favorite dish of the locals.
ANGEL, DEVOURING THE HELL
Far from shore in the water column hovering angel. This is a small krilangi clam, smoothly waving translucent pinkish wings – outgrowths on the foot. Angelfish hovers vertically in the water, amazing grace. Looking at this miracle, and not think that before us is a voracious predator, the main production of which smaller predator – krilangi clam monkfish.
Monkfish malchevskogo angel and painted, as befits the devil, in black color. His defense is a fragile shell, where he hides when in danger. But the angel of the sea shell is not a hindrance. Easily destroying its tentacles, pulls the angel in the hell mouth. In translucent the body of Angela long will be seen the traces of “black Affairs” – the remains swallowed by hell. Continue reading
