Lastlegged mammals representatives of the family, a list with photos and names

Lastogeny are divided into three families. These are subspecies of walruses, eared seals and real seals. Today they have 33 types. Sea lions and cats are also ranked to the stall. These mammals of the seas can be on land for a long time. There is a classification that ranks them to a detachment of stacked, and the other to the “predatory animals”. The lifestyle of nastysts is closely connected with the oceans and seas.

The structure of the body of animals corresponds to their lifestyle associated with swimming and diving. There are swimming membranes on the limbs flippers. The dental system contains fangs and incisors.

The structure of the stalls

The shape of the body of nastysts resembles a spindle. The length of the body is 1.3-6.5 meters, and the mass lies in a wide range of 35 kilograms of sea seals to 6,500 kilograms of sea elephants.

In the naughty limbs are flippers with five fingers, between which the membrane is stretched. They are hidden in the skin of the body. The front limbs protrude from half of the forearm, and the hind legs are visible part of the lower leg with the foot. Shoulder, forearm, hips and shin of nastysts are shortened.

The limbs of the stalls are intended only for movement, both in water and on land. Animals have very short tails. The wool on the body is short and smooth.

Flat head with wideplaced cheekbones. Dental incisors are designed to capture production. In splylegged fish, teeth remain integrity, and in the supply of the tributary organisms, they deteriorate and fall out. Almost all nastysts have a thick fat layer under the skin (thickness 7-10 cm).

Representatives from the “LastoLegal” squad have good vision. Thanks to the ability of the pupil, they will greatly see, they see perfectly in the aquatic environment.

Seals and walruses can distinguish some colors. Animals on both sides of the front part have vibrissas.

Features of nastysts

Food on the swallow is mined in water. Mostly they eat fish, crustaceans, mollusks. Only sea leopards have seals and penguins in the diet.

Animals mate, reproduce offspring, settled, save from predators on the shore. They lead a herd lifestyle. On ice or shores, you can see whole piles. Although the smell of swallowlegged is weak, they, by smell, find the whereabouts of their cubs. In the water, the nostrils close, and the sense of smell does not function.

Lastogenic have normal hearing. They hear in the air worse than in the water. The skin of animals is thick, dense.


Lastogeny live both in the cold seas of the North and in the moderate seas of the southern hemisphere. They live in internal lakes and rivers. In water, the Lastogeny quickly move and can develop speeds of up to 30 kilometers per hour, and slowly and clumsy on the shore.

In the aquatic ecological system, the Lastogeny play an important role. They contribute to holding the balance and regulation of the number of marine species.

Lastlegged fishing, pollution of the aquatic environment, climate change led to a reduction in their number. The endangered species of nastysts are under the protection of the international program.
