Millions of years ago, the ancestors of pinnipeds lived on land. These were in all probability weasel- or bear-like animals that spent more and more time in the ocean and finally tailored to this marine atmosphere. Pinnipeds are separated into three groups: earless seals, eared seals and walruses. This group includes seals, sea lions and walruses -- animals that dwell within the ocean but are in a position to return on land for long periods of time. Generally referred to as earless seals or true seals, marine mammals within the phocid household may be simply identified by looking at their ears and flippers. They also have small entrance flippers and transfer on land by flopping along on their bellies, a motion called "galumphing." At sea, true seals transfer their rear flippers back and forth like a fish tail to propel themselves through the water. They've ear holes but no external ear flaps. koala bear soft toy You can acknowledge these animals by their flippers and ears. Sea lions and fur seals are part of the otariid family and are typically referred to as eared seals. In contrast to true seals, otariids have external ear flaps. Their entrance flippers are large, and on land they're able to carry all 4 flippers beneath their bodies and walk on them. Within 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 introduced them to the brink of extinction in the nineteenth century. Walruses are in a household of their very own known as the odobenids. Fur seals, in spite of getting the phrase “seal” of their name, are literally intently related to sea lions. They've air sacs of their neck that can inflate to allow them to float as if they are wearing life preservers. Walruses are one of the biggest pinnipeds, with males reaching over 3,000 pounds. They reside within the North Atlantic and Pacific oceans, within the arctic area. Each males and females have tusks and vacuum-like mouths for sucking up shellfish from the ocean flooring.
