They have large reserve of fat in their body for winter .
Small animals have a bigger surface area than large animals, compared to their volume. This helps animals that live in cold areas to keep their surface area:volume as small as possible, and so helps them keep on to their body heat.
Larger animals have a smaller surface to volume ratio and therefore lose less body heat.
because a long time ago animals
so it helps them keep warm (daa)
Because they need heat
For insulation. It's very cold there.
A blobber is another term for a blubber, a fatty layer of adipose tissue or thick coat of fat worn by many arctic animals.

blubber

penguins dont have blubber
blubber
Many animals including whales, seals, manatees and penguins have a thick layer of fat called blubber. Only marine animals have blubber (but not every marine animal). Blubber provides buoyancy, hydrodynamic shape, and stores energy.
So it could stay warm in harsh weather and for protection from predetors
A whale keeps warm from its blubber. Its a thick layer of fat, keeping the whale from the icy waters of the ocean. The feeling of how a whale keeps warm with blubber can be tested yourself: Take a nice soft fuzzy sock and put it on your hand. Then fill a tub up with freezing cold water and place your hand inside. That's how a whale keeps warm! (not with socks). Blubber and their body metabolism
They have a thick layer of skin called blubber and they are warm blooded animals
