But after the last set of molars has worn out, elephants may starve. Elephants sometimes push trees over in search of food and can modify habitat over large areas. This enhances their ecological importance but can be destructive now that elephants are largely confined to small reserves. Great eaters need great amounts of water, though exactly how much elephants drink daily isn't clear to me. Elephants that live in more arid areas of Africa may go without water for two or three days as they travel to new water holes.
Elephants have a taste for alcohol.
In Southeast Asia, they are known to seek out fermenting durian fruits. Lions, hyenas, wild dogs, and crocodiles may prey on African elephant calves. Lions are almost extinct in Asia, but tigers are certainly large enough to tackle an Asian elephant calf. But predators pick on elephant calves at some risk, for elephants protect their young. Some of the larger saber-toothed cats were probably specialized for preying on elephants, mammoths, and mastodons.
