Elephants are the largest land animals in the world. Whales are the largest sea animals.
These two huge animals may, in fact, be related. Biologists now believe that the ancestors of elephants once lived in the sea. There is plenty of evidence to support this idea. For example, the shape of an elephant's head is similar to a whale's. Also, elephants are excellent swimmers. Some have chosen to swim for food to islands up to 300 miles from shore. Like the whale, the elephant, too, uses sounds to show anger or for other kinds of communication. Finally, in certain ways, female elephants behave much like female whales. When an elephant or a whale baby is born, a female friend stays nearby to help the mother.
