Fauna of the Mediterranean sea

The Mediterranean sea is a part of the ancient Tethys ocean, with an area of 2.5 million square kilometers; the volume of water in the sea is about 3.8 million cubic km, and average depth is more than 1.5 thousand meters. In such considerable dimensions of the Mediterranean sea, its fauna is characterized by significant species diversity, but populations of animals of each species is relatively small. This is mainly due to a small number of plankton in marine waters.

In the Mediterranean there are 593 species of fish, of them in Israeli waters, home to 291 species (mackerel, herring, mullet, tuna, dolphinfish, palamidi, horse mackerel and many others). The Mediterranean coast of Israel encountered 4 species of flying fish. Many fish in the Mediterranean are of commercial importance.

Over the past few years, the size of the catch in some areas, Israeli water decreased in 3 times. This is not a serious food problem for Israel, because fishing gives the country only 16% received at the counters of local fish, the rest is grown (2005 data). However, the fauna of the Mediterranean sea may soon be poorer in several kinds of bottom flat sharks. Disappears in the Mediterranean and bluefin tuna.

Muricidae), which have served as raw materials for purple paint.
