Although seals are fleshy and cute, they also have "leopards" in their names, and they are carnivores.

The most important of the seals is the leopard seal. The shape of the leopard seal resembles a dinosaur, and its body size is relatively large among seals, with a body length and a weight of 300-350kg. Fish and squid are a daily meal, but it is homeothermic animals that it preys on, so seals can attack penguins, even small cetaceans, and other seal relatives.

Extended: The seal's front feet are shorter than those of the hind feet, and the hairy fin feet have nails and 5 toes. The ears become extremely small or degenerate to only two holes, which can be opened and closed freely when swimming.

When swimming, it mostly relies on its hind feet, but its hind feet cannot bend forward, and its heels have degenerated to be different from sea lions and fur seals, so when it moves on land, it always drags its sleepy hind limbs, bends and crawls, and leaves a line of twisted marks on the ground. Sea lions and walruses are close relatives of seals, and they have earshells and hind limbs that turn forward to support their bodies.
