Tens of millions 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 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 stay in the ocean but are in a position to come on land for lengthy periods of time. Typically referred to as earless seals or true seals, marine mammals within the phocid family can be easily recognized by taking a look at their ears and flippers. They even have small front flippers and move on land by flopping along on their bellies, a movement referred to as "galumphing." At sea, true seals transfer their rear flippers back and forth like a fish tail to propel themselves through the water. They have ear holes however no external ear flaps. You possibly can acknowledge these animals by their flippers and ears. Sea lions and fur seals are part of the otariid family and are generally known as eared seals. In contrast to true seals, otariids have exterior ear flaps. Their entrance flippers are large, and on land they're able to convey all 4 flippers underneath their bodies and stroll on them. Within the water, they swim using their front 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 nineteenth century. Walruses are in a household of their own referred to as the odobenids. Fur seals, in spite of having the word “seal” in their name, are literally closely related to sea lions. They've air sacs in their neck that may inflate to permit them to float as if they're wearing life preservers. Walruses are one among the biggest pinnipeds, with males reaching over 3,000 pounds. They stay within the North Atlantic and Pacific weighted teddy oceans, in the arctic area. Both males and females have tusks and vacuum-like mouths for sucking up shellfish from the ocean floor.
