The phrase "pinniped" means fin- or flipper-footed and refers to the marine mammals which have front and rear flippers. Hundreds of thousands of years in the past, the ancestors of pinnipeds lived on land. These have been in all probability weasel- or bear-like animals that spent increasingly more time in the ocean and ultimately adapted to this marine environment. Pinnipeds are separated into three groups: earless seals, eared seals and walruses. This group consists of seals, sea lions and walruses -- animals that stay in the ocean but are ready to come back on land for long periods of time. Generally referred to as earless seals or true seals, marine mammals in the phocid household might be simply identified by taking a look at their ears and weighted teddy flippers. They even have small entrance flippers and move on land by flopping along on their bellies, a movement known as "galumphing." At sea, true seals move their rear flippers back and forth like a fish tail to propel themselves via the water. They've ear holes but no external ear flaps.

Within the water, they swim utilizing 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 19th century. Walruses are in a family of their very own called the odobenids. Fur seals, in spite of having the phrase “seal” in their identify, are literally intently associated to sea lions. They've air sacs in their neck that may inflate to permit them to float as if they are sporting life preservers. Walruses are one in all the most important pinnipeds, with males reaching over 3,000 pounds. They stay in the North Atlantic and Pacific oceans, in the arctic region. Each males and females have tusks and vacuum-like mouths for sucking up shellfish from the ocean flooring. Canadian legal guidelines, however limited hunting by the Inuit individuals is allowed.
