What predators does a African elephant have?

Elephants are probably the largest living mammals on earth. They don't have any natural predators that can attack a full grown elephant. However, In Africa lions and packs of hyenas have been known to attack an injured or extremely old elephant or an elephant calf that has strayed away from its herd. In Asia, a large adult Tiger or a Lion can attack a young elephant calf. Humans are the biggest enemies to elephants in all its habitats. Armed with guns hunters and poachers are the biggest threat to elephant numbers.
