Pinnipeds [2] are the seals and their relatives, a group of semi-aquatic marine
|
|
mammals. The Pinnipedia is in the Order Carnivora. There are three seal
|
|
families: Odobenidae (walruses), Otariidae (eared seals, including sea lions
|
|
and fur seals), and Phocidae (true seals).[3]
|
|
|
|
Seals are sleek-bodied and barrel-shaped. Their bodies are well adapted to the
|
|
aquatic habitat where they spend most of their lives. Pinnipeds have flippers
|
|
for hands, big bulky bodies, doggish faces, and big eyes. Unlike cetaceans,
|
|
pinnipeds have their noses on their faces, and each nostril of the nose closes
|
|
when the pinniped goes underwater. Like cetaceans, pinnipeds have a thick layer
|
|
of blubber (fat) just under their skin: this blubber keeps them warm in cold
|
|
waters and keeps them fed during times when food is not easily found. When they
|
|
cannot find food, they live off the fat in the blubber.
|
|
|
|
Pinnipeds are carnivorous. This means they eat only meat (such as fish or
|
|
squid) and not plants. However, almost all pinnipeds can be eaten by polar
|
|
bears, sharks and killer whales.
|
|
|
|
Seals are often trained in zoos or aquariums to put on shows. However, in
|
|
Sweden, it is illegal to train a seal to balance a ball on its nose.[4]
