The big white bones sticking out of an elephant's face are really big teeth called tusks .
Elephants have big ears that are used for more than just hearing.
They use their ears for keeping cool by fanning them, and to let other animals know if they're mad by flapping them. They also stick there ears out to greet each other. Elephants can hear sounds that are too low for us to hear. They make low rumbling noises that their friends can hear even when they're miles away. It's easy to tell the difference between African and Asian elephants.
