Scientists refer to this motion as a “clap.” Sea lions are the only aquatic mammals that swim this way. Seals, walruses, whales, otters, and others rely on the back end of their bodies—their tail—to produce thrust. Instead, the sea lion tail is used like a rudder.

Seals are pinnipeds, a group of animals with three separate families—phocidae (eared seals), otaridae (non-eared seals), and odobenidae (walruses)—that are the only mammals that feed in the water and breed on land. Where do they come from? Evidence suggests that pinnipeds evolved from a bear-like land animal that hunted in the water for food.
Evolutionarily speaking, seals are thought to be most closely related to bears and the group of animals that includes weasels and otters, as well as skunks, raccoons, and red pandas.
All seals are carnivores, eating fish, crustaceans, and krill (shrimp like animals). Seals are related to terrestrial carnivores such as dogs and cats; they breed and rest on land, but are equally comfortable on land or in water.
Although they are often associated with the polar regions, seals may live near tropical beaches and in more moderate climates. With over thirty varieties, seals are highly intelligent mammals that can stay under water for up to two hours.
