The African elephant is the largest living land animal, larger than the Asian elephant. They live in family groups headed by females called cows. Males are called bulls. African elephants are about 10 feet tall and weigh roughly 6 tons, with males being larger. They have wrinkled, gray-brown, almost hairless skin and large ears up to 5 feet. Their trunk is used to get food and water, which includes roots, grasses, leaves, fruit, and bark. Elephants are excellent swimmers but are endangered due to habitat loss and poaching for their ivory tusks.
