underwater world of the seas and oceans diverse.Here in the depths of the multimeter live scenic sea animals.The names of many of them were given by scientists in view of their distinctive features: body shape, fin, color, patterns on the skin, the similarity with some earthly individuals, etc.So, some invertebrates have been called the "starfish", "truffle", and so on. D.
marine species
underwater creatures can be divided into the following groups:
- invertebrates;
- mammals;
- crustaceans;
- fish;
- turtles and snakes.
Marine invertebrates
Invertebrates include the following organisms: sea anemone, sea lilies, starfish, sea urchins, clams, sponges, corals, jellyfish, squid, nautilus, octopus, oysters, Glotur, triakny and others. TheseAnimals deprived of the axial skeleton.They mostly live in tropical seas and stand out for their bizarre shapes and the brightest colors.Anyone who sees them for the first time in the water, not even aware that they are living creatures.Rather, you can decide what is peculiar plants than marine animals.The names of each point to the distinctive features of its "master."Thus, the sea sponge is a sponge-like structure, and sea urchin covered with thorns, starfish its star shape.
Marine mammals
According to some theories, marine mammals are our ancestors.For the first time the world was born in the water.Pinnipeds (seals, fur seals, sea lions, walruses, etc..) And whales existed about 26 million years ago.Some of these species were lost, they were replaced by new ones.Today, science knows about 120 species of mammals - the inhabitants of the seas and oceans.They can be grouped into three broad groups: whales, dolphins, seals.Marine animals, pictures and names listed above are perhaps the most unique and interesting creatures on the planet.Bottlenose dolphin, common dolphin, striped and spotted dolphins - these animals are the most studied zoology and are in constant contact with the man, but much of their behavior remains a mystery to us.
Crustaceans
These animals belong to a class of aquatic animals such as arthropods.It includes crayfish, crabs, lobsters, prawns, lobsters and others. These marine animals whose names can be found on the menu of Japanese, Chinese, Italian and other cuisines, are the most valuable foods rich in iodine, protein, phosphorus and other nutrients.However, some of them are very rare and are listed as endangered.
Fish
This is the largest group of marine life.All kinds of colors and shapes, they are not.They can range in size from microscopic to giant.Fish can be a peaceful inhabitant of water depths and bloodthirsty predator, which primarily include the so-called "wolves" of the seas - sharks.These are large predatory sea animals, whose names indicate with any of the beasts of the earth they are compared.For example, there are cat, tiger, bull, leopard, zebra shark, and not all of them are bloodthirsty creatures.By the way, leopard - a peaceful being who almost never attack humans, unlike the great white shark - the greatest hunter.It is said that she is very cunning and clever.But the ramp, for example, is very dangerous for humans, because it carries a significant electrical charge and can cause death.However, most fish - are peaceful creatures who become easy prey for people.
Turtles and snakes
Turtles - are the only reptiles that have a shell.These marine animals are very intricate name: hawksbill, loggerhead, Ridley and green turtle.Some of them are large.As for sea snakes, they are close relatives of asps.However, the way of life they are very different from their terrestrial counterparts.
