How much food does an elephant typically eat in one day?
Most elephants in the wild will eat between 300 and 500 pounds of vegetation and drink 50 gallons of water every day. They are known to spend 18 to 20 hours a day eating.
They are considered browsing animals, or animals that are known to feed or nibble off tree foliage, bark, twigs, loose fruits, leaves, shoots, and tall grasses. Apparently this works well for the elephant, these giant vegetarians typically live up to 70 years.
