What noise do seals make?

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.
