The bottom of the ocean or on the seabed. Underwater world and the inhabitants of the seabed.
At the bottom of the ocean, at three kilometer depth the pressure at three hundred times more than the top. Marine snow need many months to sink to the seabed from the surface. Away from the rocky shores of the continents, the bottom of the ocean extends for thousands of kilometers and gradually sinks down.
On the seabed, the silt could be seen faint traces, signs that even here there is life. Who were the inhabitants of the seabed?
Underwater world and on the ocean floor is rich and diverse. So, sea urchins . sitting on the bottom of the ocean, sift the deposits of silt. Shrimp . elegantly standing on tiptoe, fastidiously plucked particles of food that gets them.
And in the deep sea, as everywhere else, if there are grazers, there are hunters. Monkfish almost unrecognizable amongst the sand on which it lies. He doesn’t waste energy on a chase, it attracts prey with lure? If necessary, he can wait for days until you come the food is the right size.
Scavengers have to move to find their food. Crabs are able to detect the slightest taste in the water, and it helps them quickly find the body that fell from above. The eels also feed on the corpses of dead inhabitants of the underwater world. After any lifeless body trapped in the ocean will sink to the bottom of the sea in the next few hours will be crazy competition between fans of carrion of all kinds. Everyone wants whatalso share. After all, it is for them a matter of life and death.
Another one of the inhabitants of the seabed – Nautilus . He spends his days hiding four hundred meters depth, but with nightfall, he rises to the reefs in search of food. Its graceful shell contains gas-filled chambers that control its depth. Clam swims against streams of water, which flies out of the siphon, but as the shell sails ahead, he can’t see exactly where floating. His closest living relatives are squid and octopus – in the course of evolution, both lost its shell, and the octopus has become one of the largest predators. This is the master of disguise. The Nautilus kept away from him. Its little tentacles are armed with highly developed chemical sensors that can detect traces of both predators and prey. He uses his water jets to dig in the sand. Because he spends so little energy, he needs to eat only once a month. At daybreak they go into deeper water, and at nightfall, without losing vigilance, they are looking for among the plankton small fish.
The underwater world is amazing and mysterious and talking about it endlessly. We offer you to admire the underwater world and meet the inhabitants of the seabed.
