The sea world is very interesting and various. He cannot be recognized about all inhabitants - for this purpose there will not be enough also life. However some features, for example, ways of movement of marine animals to study very interestingly.
Instruction
1. The starfish is one of the most mysterious and beautiful animals. And they move at the expense of special ambulakralny legs on which suckers are located. They help starfishes to keep on reefs, rocks and other objects.
2. The sea hedgehog is the closest relative of starfishes and very ancient animal. For rescue from dangerous predators he uses a huge number flexible, capable to be extended and be reduced legs. Thanks to the fact that on the ends of these legs suckers are located sea hedgehogs can move on steep rocks, be attached to a bottom in any place and get food.
3. The squid is the fastest swimmer in the ocean. He moves a tail forward, soaking up at the same time water under a fold cloak, and then, closing it, with a force throws out water through a funnel under a beak. The fin is used as a wheel and the stabilizer, and tentacles as a wheel on turns.
4. Different types of jellyfishes have ways of movement excellent from each other. Some move by means of reduction of muscles (jet propulsion), others use the wind force or a current.
5. An octopus - it the sea being is very interesting thanks to what has two ways of movement. He can creep on a firm surface, using the suckers on tentacles, and can move, gathering water in a mouth and pushing out in the opposite direction through a special funnel.
6. The holothuria or a sea cucumber - these animals move a little, more they lie "on one side". And small legs in the form of tubules via which channels the holothuria pumps over water help to start moving to them.
7. Nautilus. At these animals a way of movement not such, as at other mollusks because their leg changed: its end turned into a funnel which allows them to float rather not bad. Thus, nautiluses or creep on a bottom by means of tentacles, or, regulating immersion depth filling a cavity of the sink with water or gas, slowly float.
8. Slope. The way of movement of these beings is very beautiful. They move by means of the big fins reminding wings. The slope floating in the sea really reminds an eagle who soars in heaven.
9. Crabs move quite funny. They quickly move with the small legs, having exposed claws for protection forward. At the same time it turns out that the crab runs sideways.
10. Having studied ways of movement of some marine animals, it is necessary to make sure that they are quite various and interesting. But it is impossible to forget that there are also animals who lead a motionless life. Corals, oysters and triadna concern them, for example.
