Quick Summary

Eared seals, also known as Otariidae, are a family of pinnipeds that include sea lions and fur seals. They are distinguished from true seals (family Phocidae) by their external ear flaps and their ability to rotate their hind flippers forward, allowing them to walk on land. This contrasts with true seals, which have ear holes instead of external ears and cannot move their hind flippers under their bodies, forcing them to move on land by wriggling on their bellies.123

Eared seals are generally more vocal than true seals and use their long front flippers for propulsion when swimming, while true seals primarily use their hind flippers. Both types of seals are carnivores, feeding mainly on fish, squid, mollusks, and crustaceans, though some species have more specialized diets.23
