An adult male African elephant can weigh up to 16,538 pounds. Their massive size requires them to eat between 220 to 440 pounds of vegetation per day. Males can grow to a height of 11 to 13 feet and a length of up to 30 feet.
These elephants are the largest terrestrial animals that exist in modern times. The gestation period for African elephants is 22 months. After that, the female gives birth to a calf that can weigh up to 265 pounds. The female African elephant does not get as large as her male counterpart. Females can reach weights of up to 7,127 pounds. Elephant growth is unusual compared to other mammals, as they grow throughout their entire lifetimes. After sexual maturity between the ages of 12 to 14, the growth slows down considerably.
