Morphological characteristics of seals: seals are marine animals and mammals (viviparous). Their bodies are streamlined and their limbs become fins, which is suitable for swimming. Seals have a thick layer of subcutaneous fat to keep warm, provide food reserves and generate buoyancy. Seals are all spindle-shaped and suitable for swimming. Their heads are round and look like domestic dogs. They are all hairy and their forelimbs are shorter than their hind limbs. Seals have shorter forelegs than hind feet, and hairy flippers have nails, which are five toes. Ears become extremely small or degenerate into only two holes, which can be opened and closed freely when swimming. When swimming, most people lean on their hind feet, but their hind feet can't bend forward, and their heels have degenerated. Unlike sea lions and seals, they can't walk. Therefore, when they move on land, they always drag their heavy hind legs and bend over to crawl, leaving lines of twisted marks on the ground. Sea lions and walruses are close relatives of seals. They have ear shells, and their hind limbs can rotate forward to support their bodies.
