Like the otter,

the beaver is a very good

swimmer and diver. It has

a distinctive flat tail,

which it uses to whack the

ground and warn other

beavers of danger.

Beavers in the wild

build their homes out of

branches, which can lead

to flooding. But dams are

important to beavers.

They raise the water level

so that the entrance to

their burrow is deep

enough to not ice

over in winter.
