These seals are so big and round! Why is that? Do you have any ideas
about how being big and round could help an animal?

These seals live in very cold places—and they swim in freezing cold
water. To stay warm, they have a thick layer of fat called blubber.
Their blubber acts like a blanket that keeps them warm.

This seal pup doesn’t have any blubber yet. Its fur keeps it warm while
it drinks its mother’s milk and grows fat. The white fur helps it blend
in with the snow! It will turn gray when it grows up.

The sea lion’s front flippers are longer than the seal’s. Watch both
animals move on land. The sea lion uses its flippers like legs! The seal
wiggles like a caterpillar. It’s easy to see the difference now!

This sea cow is having lunch. It’s not eating sand! It’s slurping up
seagrass, stirring up sand in the process. The yellow fish follows it,
ready to snap up any small animals unearthed by the sea cow.

This young elephant seal claimed a small town as his own—and
practiced his fighting skills on cars and trucks! The cars never fought
back so the seal was always the winner!

I bet you can guess why these seals are called elephant seals. Adults
have noses that kind of look like an elephant’s trunk!
