The phrase "pinniped" means fin- or flipper-footed and refers to the marine mammals that have entrance and rear flippers. Thousands and thousands of years in the past, the ancestors of pinnipeds lived on land. These had been probably weasel- or bear-like animals that spent more and more time within the ocean and eventually adapted to this marine atmosphere. Pinnipeds are separated into three groups: earless seals, eared seals and walruses. This group contains seals, sea lions and walruses -- animals that dwell in the ocean but are able to come on land for long durations of time. Typically known as earless seals or true seals, marine mammals in the phocid household will be simply identified by looking at their ears and flippers. They even have small entrance flippers and move on land by flopping alongside on their bellies, a motion known as "galumphing." At sea, true seals move their rear flippers again and red panda teddy forth like a fish tail to propel themselves by means of the water. They have ear holes however no external ear flaps. You can recognize these animals by their flippers and ears. Sea lions and fur seals are a part of the otariid family and are typically known as eared seals. Not like true seals, otariids have exterior ear flaps. Their entrance flippers are large, and on land they're able to deliver all 4 flippers underneath their bodies and stroll on them. In the water, they swim using their entrance flippers like oars. They have longer flippers than sea lions, together with a luxuriant coat of fur that was so prized by hunters that it brought them to the brink of extinction in the nineteenth century. Walruses are in a family of their own called the odobenids. Fur seals, in spite of having the word “seal” of their title, are literally carefully associated to sea lions. They have air sacs of their neck that can inflate to allow them to float as if they're sporting life preservers. Walruses are one of the biggest pinnipeds, with males reaching over 3,000 pounds. They live within the North Atlantic and Pacific oceans, within the arctic region. Each males and females have tusks and vacuum-like mouths for sucking up shellfish from the ocean ground.
