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 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
