Which animals would want to attack an elephant? Not many! Elephant calves could be a potential meal for hyenas, lions, leopards, or crocodiles, but as long as they stay near Mom or their herd, they have little to worry about. If an elephant senses danger, it trumpets a loud alarm call to alert the others. The herd then forms a protective ring, with youngsters in the middle and the adults facing out to confront a potential predator. A healthy adult elephant’s only foe is a human poacher with a powerful rifle.
