Whales and dolpins:

Whales and dolphins are mammals, that is to say, warm-blooded animals with backbones that breathe air and suckle their young. Millions of years ago, their ancestors lived on land but, because they now spend all their time in water, their bodies have adapted to living in the sea and are streamlined much like those of fish.

Because they need to breathe air, whales and dolphins must be able to hold their breath for a long time underwater - some of the really big whales can hold their breath for over an hour!

Because it is so dark underwater, whales and dolphins do not rely on their eyesight, but rather use sound to help them find their way, by I sending out sound waves, which bounce off other objects. If a whale or dolphin detects an echo, it knows that there is something in the way. This is known as echolocation. Whales and dolphins are known as cetaceans - about 79 species occur around the world, 38 of which are found in the waters off southern Africa’s coast.
