A long time ago, even before dinosaurs roamed the Earth and were the first sharks that these extraterrestrial beings already inhabited the seas and oceans. They are the most ancient inhabitants of our planet . lived on Earth for another 500 to 700 million years ago.
This jellyfish is one of the most amazing, beautiful and mysterious sea creatures.
Jellyfish seem to be supernatural creatures, alien beings largely thanks to its strange forms and colors. The nature has created them according to his own, some incredible drawings: the body resembles an umbrella, or bell, sometimes the ball.
His name jellyfish has been because of the similarity with a wiggling hair-the legendary snakes of the Gorgon Medusa from Greek mythology. (Photo Animal Theory):
There are about 2000 different species of jellyfish. Some live in fresh water, others are found in seas and oceans. (Photo By The Tahoe Guy):
As already mentioned, jellyfish have lived on Earth for another 500 to 700 million years ago. This is a very long time. For example, the first dinosaurs appeared about 225 million years ago and the most ancient representatives of the sharks existed about 420-450 million years ago. (Photo Animal Theory):
The structure of a jellyfish is also incredibly: primerena they consist of 95% water, 3-4% — of salt and 1-2% — from protein. They have no heart, no eyes, no circulatory system or gills.

Most of the fish for reproduction lay eggs, but there are a few species that give birth are ready fry. This, for example, the great white shark.
Mudskipper is a fish which spends the majority of his time out of the water and can “walk” on their own fins. In the gills the jumpers for a long time kept a small supply of water. They can also breathe through the pores of its wet skin.
The Stingray has more than 27,000 taste buds. Compared to him, a man almost four times less – “only” 7 000.
Most brands of lipstick contain substances included in the composition of fish scales. They give the lipstick a unique luster.
Fish lungfish can live out of water for several years. It secretes a slimy protective coating and in dry years, buries itself in the clay, sucking the air through the built-in breathing tube, which comes to the surface. Do lungfish have lungs and gills and.
Seahorses are the only fish able to swim upright.
Some fish like the white shark, can raise her body temperature to hunt in cold water.
Fish use sounds with low tones to pass messages to each other. They moan, growl, croak, mutter, hiss, whistle, creak and squeal. They crack the bones and grind their teeth. However, fish don’t have golosovatj. Continue reading
Black sea – an inland sea basin of the Atlantic ocean. The Bosporus connects to the sea of Marmara, then through the Dardanelles with the Aegean and Mediterranean seas. The Kerch Strait connects the sea of Azov. North sea cuts deeply into the Crimean Peninsula. On the surface Black sea water passes the border between Europe and Asia Minor.
A characteristic feature of the Black sea is complete (except for some anaerobic bacteria) absence of life at depths greater than 150-200 m due to the saturation of deep layers of water with hydrogen sulfide.
The climate of the Black sea, due to its mid-continental situation, mainly continental. The black sea coast of Caucasus and the southern coast of the Crimea being protected by mountains from cold Northern winds and as a consequence, have a mild Mediterranean climate and South-East of the Tuapse — humid subtropical climate. A significant impact on the weather over the Black sea has the Atlantic ocean, which originates most of the cyclones at sea bringing bad weather and storms. In the North-East coast, especially in the area of Novorossiysk, low mountains are not a barrier to cold Northern air masses, which, moving through them, cause a strong cold wind (Bora), the locals call it “Nord-OST”.South-westerly winds usually in the black sea region brought a warm and wet Mediterranean air mass. As a result, for the greater part of the territory sea is characterised by warm wet winters and hot dry summers.
The black sea fills the insulated cavity, located between Southeast Europe and Asia Minor. This depression was formed in the Miocene epoch, during an active orogeny that divided the ancient Tethys ocean into several separate water bodies (of which more later, except the Black sea, formed the Azov, Aral and Caspian seas).
