It’s known to us all that elephants are the biggest animals on land.
There are two kinds of elephants: African elephants and Indian elephants. The African elephant has a round head and very big ears. It has long teeth. Each of them can be as long as 3.4 meters and as heavy as 103 kilograms. African elephants live in forests in Africa. They eat leaves, roots and fruits. Indian elephants are smaller than African elephants. They are found in forests in India, Malaysia and some other countries in South Asia. They live on grass. They can be trained to do a lot of heavy work and amuse(逗乐)people.
An African elephant lives as long as a man does. But an Indian elephant does not live that long.
