Do Weddell seals have fur?
The Weddell seal grows a thin fur coat around its whole body except for small areas around the flippers.
Can Weddell seals breathe underwater?
Weddell seals can dive up to 2,000 feet down and stay under for up to 45 minutes. But no matter how deep they dive, like all marine mammals, they must surface to breathe. If natural openings are not available, Weddell seals use their teeth to open and maintain air holes in the ice pack.
How has the Weddell seal adapted?
Smooth, streamlined shape to pass easily through the water. Large eyes to help hunting prey under water and frequently under ice where light levels are very low. Whiskers (vibrissae) that help the seals feel their way in the dark when catching prey.
How do Weddell seals keep warm?
Body Temperature Regulation When cold, seals rely on their thick layer of blubber, or fat, to keep their organs insulated. Younger seals’ skin is kept warm by a layer of water-repellent fur, which remains until the seals grow the fat layer.
What is Weddell seals life span?
How long do Weddell Seals live? Weddell Seals live 30 years on average.
What is the Weddell seals habitat?
The Weddell seal is found in circumpolar Antarctica and is most abundant near the Antarctic coast. In the austral winter it moves northward with the expansion of the pack ice, staying in the water to avoid blizzards and poking its head through breathing holes.
How does Weddell seal keep itself warm?
Weddell seals are adapted to the severe cold like many other Arctic and Antarctic animals. They have large amounts of blubber and thick fur to keep them warm in the cold. They also have other well-known adaptations such as whiskers for sensing prey, flippers for swimming, and streamlined bodies for faster and more efficient swimming.
