Female elephants spend their entire lives living in large groups called herds. Male elephant leave their herds at about 13 years old and live fairly solitary lives from this point.
Elephants have no natural predators. However, lions will sometimes prey on young or weak elephants in the wild. The main risk to elephants is from humans through poaching and changes to their habitat.
Elephants have large, thin ears. Their ears are made up of a complex network of blood vessels which help regulate their temperature. Blood is circulated through their ears to cool them down in hot climates.
