Tens of millions of years in the past, the ancestors of pinnipeds lived on land. These were most likely weasel- or bear-like animals that spent more and more time in the ocean and finally adapted to this marine setting. Pinnipeds are separated into three groups: earless seals, eared seals and walruses. This group consists of seals, sea lions and walruses -- animals that dwell within the ocean however are in a position to come on land for long intervals of time. Typically referred to as earless seals or true seals, marine mammals within the phocid household can be easily recognized by looking at their ears and flippers. They also have small front flippers and transfer on land by flopping alongside on their bellies, a movement known as "galumphing." At sea, true seals transfer their rear flippers back and forth like weighted teddy a fish tail to propel themselves by way of the water. They've ear holes but no exterior ear flaps. You'll be able to acknowledge 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. Unlike true seals, otariids have external ear flaps. Their front flippers are giant, and on land they can carry all 4 flippers underneath their our bodies and stroll on them. In the water, they swim using 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 in the 19th century. Walruses are in a family of their own known as the odobenids. Fur seals, in spite of getting the phrase “seal” of their title, are actually carefully associated to sea lions. They've air sacs in their neck that may inflate to permit them to float as if they're carrying life preservers. Walruses are considered 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. Both males and females have tusks and vacuum-like mouths for sucking up shellfish from the ocean floor. Canadian legal guidelines, however restricted looking by the Inuit individuals is allowed.
