Whales
Whales are sea-living mammals.
They therefore breathe air but
cannot survive on land. Some species
are very large indeed and the blue
whale, which can exceed 30 m in
length, is the largest animal to have
lived on earth. Superficially, the
whale looks rather like a fish, but
there are important differences in
its external structure; its tail
consists of a pair of broad, flat,
horizontal paddles (the tail of a fish
is vertical) and it has a single nostril
on top of its large, broad head. The
skin is smooth and shiny and beneath
it lies a layer of fat (blubber). This
is up to 30 cm in thickness and serves
to converse heat and body fluids.
