a seal is a very cute, goofy sea creature. On the whole, their body shape is relatively round and fat, which is also one of the important reasons for their dull appearance. The seal's head is almost attached to its body, and it looks like it has no neck. In fact, seals have necks, but the necks are very short and it is not easy to distinguish them. The seal's short neck is one of its important characteristics, which can distinguish it from some similar animals. For example, seals and sea lions can be distinguished by the length of their necks, which are very short, while sea lions have longer necks, and when standing up, sea lions are significantly higher than seals.
Seals refer to animals in the order Carnivora, the suborder Pinnipedia, and the family Phocidae, among which "pinniped" refers to their limbs. Seals do have four limbs, and their limbs are equivalent to the legs of terrestrial animals. However, the legs of seals are not the same as the legs we usually understand, their legs are more like the fins of fish, so they are called "flippers".
If we can look closely at the limbs of seals, we will find that their legs are quite different from those of terrestrial animals. Seals have five toes on their limbs, which are sharp and webbed, so they are similar to the fins of fish in appearance. The rear two flippers are larger and extend to the rear. With the help of flippers, seals can move on land, but they can't move as freely as land animals.
