Hundreds of thousands of years ago, the ancestors of pinnipeds lived on land. These have been in all probability weasel- or bear-like animals that spent increasingly time within the ocean and ultimately tailored to this marine setting. Pinnipeds are separated into three teams: earless seals, eared seals and walruses. This group contains seals, sea lions and walruses -- animals that dwell within the ocean but are in a position to come on land for long periods of time. Typically referred to as earless seals or true seals, marine mammals within the phocid household can be simply recognized by looking at their ears and flippers.

In the water, they swim utilizing their entrance flippers like oars. They've longer flippers than sea lions, together with a luxuriant coat of fur that was so prized by hunters that it introduced them to the brink of extinction within the 19th century.
