Hundreds of thousands of years ago, the ancestors of pinnipeds lived on land. These were most likely weasel- or bear-like animals that spent increasingly time in the ocean and eventually adapted to this marine surroundings. Pinnipeds are separated into three groups: earless seals, eared seals and walruses. This group contains seals, sea lions and walruses -- animals that live within the ocean but are able to return on land for lengthy intervals of time. Sometimes referred to as earless seals or true seals, marine mammals within the phocid household can be simply recognized by taking a look at their ears and flippers.

Within the water, they swim utilizing their entrance flippers like oars. They've longer flippers than sea lions, along 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.

They have air sacs in their neck that can inflate to allow them to float as if they're wearing life preservers. Walruses are one of the largest pinnipeds, with males reaching over 3,000 pounds.
