The elephants four teeth are molars. About every four years, the molars fall out and are replaced by new ones. The ears of a full-grown African elephant are about five to six feet long and four feet wide. They sometimes flap their ears to cool themselves. An elephant's trunk is actually part nose and part upper lip.
Elephants can breathe through their trunks.
They can also smell and pick up things with it. When it is hot, elephants like to get into water and mud. They also use their trunks to spray water and dust on their bodies. Wrinkles on their skin trap the water and help with the cooling. You can see elephants in zoos.
