Elephants can swim very well. They can also hear very well with their big ears. They are about 2.5 metres tall and weigh up to 5,400 kg. Only the males have tusks. They have very thick, wrinkled, grey-brown skin with very little hair. Elephants are in extreme danger because humans kill them for ivory tusks and destroy their environment. Baby elephants are born weighing 200 pounds (90 kg)-more than most human adults! The females are called cows and males are called bulls.
Elephants breathe through two holes (nostrils) at the end of their trunk; the trunk is also used to get water and food. To get water, the elephant sucks water into the trunk, then puts the trunk in his mouth and shoots the water into it. The trunk is like a hand. Elephants eat roots, grasses, leaves, bark, bananas and sugar cane. Working bulls can eat up to 300-600 pounds (130-260 kg) of food each day.
