Water mammals

Underwater lives

Seals spend most of their

lives in water, but return

to land to have babies.

They have a thick layer

of fat, called blubber,

which keeps them warm.

Seals are

often very

playful in

the water.

Sea lions can walk

more easily than

other seals because

their flippers are

able to move in

several directions.

Sea lion

Not all mammals live on land – some live in

water. Unlike fish, however, water mammals

have to go to the surface to breathe.

Seals

Seals, which include sea lions

and walruses, have flippers

instead of arms and legs,

which make them very good

at swimming but not good

at walking.
