Who lives here?

inhabitants of the Black Sea - algae and animals.First - a few hundred species, the second - more than two and a half thousand.Of these, 500 - unicellular, 1900 - invertebrates, 185 - fishes, 4 species - mammals.

Phytoplankton

Black Sea ... its inhabitants - all sorts of algae: tseratsium, peridinium, eksuviella and others.In the early spring a peak growth of algae.Sometimes water seems to change color, becoming of turquoise blue and brown.This is due to the power division of plankton (algae bloom).Intensive breeding Rhizosolenia, hetotserosy, skletonema.While the mass reproduction of phytoplankton is dated to the beginning - the middle of summer.Among benthic algae Phyllophora be noted that more than 90% of the total weight.Phyllophora extended to the northwest.Cystoseira other algae, is more common in the southern shores of the Crimea.There is inhabited by many young fish, feeding and living among the algae (30 species).

benthic animals

Among the animals that live on the ground or in the ground floor of the sea (benthos) - various invertebrates: crustaceans and crabs, worms, rhizopod, sea anemones and mollusks.To apply to benthos and gastropods, for example, all known Rapana, and other inhabitants of the Black Sea.The list goes on: mussels, scallops, clams - elasmobranch.Fish: flounder, rays, sea dragon, ruff and others.They constitute a single ecosystem.And a single food chain.

inhabitants of the Black Sea - Dolphins (toothed whales)

total of these three types of waters.The largest - the bottlenose dolphin.Slightly less - common dolphins.The smallest - porpoises, and harbor porpoises.

Bottlenose Dolphin - is the most common occupant of dolphinariums.For this kind of science is of great importance.It studied bottlenose dolphin scientists around the world for the presence of mind.They - born circus.Bottlenose dolphins gladly perform a variety of tricks.The impression is that they really have a reason.It is not even training, but some cooperation and understanding dolphins and humans.Bottlenose dolphins only understand the affection and encouragement.The punishment does not perceive at all, then any trainer cease to exist.

Lifestyle dolphins - gregarious and family (up to ten generations together).The head of the family - the female.Males are kept separate clan, showing interest to females generally only during mating.

Bottlenose dolphins have enormous power.But a person it is usually not used.With people Dolphins maintain the most friendly relations like brothers on reason.Throughout the long history of the relationship between man and the dolphin was not seen any attempt to offend the "big brother".But people often violate the rights of dolphins, putting them on the experiments, was imprisoned in the dolphinarium.About

language is written a lot of dolphins.We will not say, as some scholars that he is richer human speech.However, it contains a huge range of sounds and gestures which allows still talking about a dolphin mind.And the amount of information that they can transmit and large (more than human) brain - what hard evidence.

remains to add that of mammals are found in the Black Sea seals, but recently there has been very little because of the harmful human activity.

On land

Not only the residents of the sea and feed on the human race seafood.Some species of birds living on the ground, get their food in the water.The inhabitants of the land, producing food in the sea - gulls and cormorants it.They feed on fish.Cormorant, for example, can perfectly swim and dive, eating large amounts of fish, even when full.Features allow his throat to swallow a rather large prey.Thus, the birds - the main inhabitants of the land, producing food in the sea Black Sea coast of the Caucasus and Crimea.
