The Biggest Animal of All

What do you think is the biggest animal in the world?

Elephant? King Kong? Dinosaur? No, The answer is whale.



Whales are warm-blooded animal. They live in the water. They look like fish. They swim like fish. But they aren’t fish at all. The biggest whale of all is the blue whale.

Millions of years ago, their ancestor lived on land. They walked around on four legs and were hairy like other animals. Then, nobody knows exact why, they began living more and more like fish. They lost their hair. And when their bodies became smooth, they could glide through the water easily. Their hind legs disappeared. They grew a thick layer of fat called blubber under their skin to keep themselves warm in the cold seas. With these and a few changes, they get along very nicely in their watery home.

But because whales are not fish, they can’t stay under the water too long, they have to come up for air once in a while, if not they will drown. When they come up, the first thing they do is blow out the breath they have been holding. When their warm breath hits the colder air, it makes a cloud of mist called whale’s spout.
