elephant
Either of two ungulate species in the order Proboscidea (family Elephantidae), characterized by their large size, long trunk, tusks, massive legs, large ears, and huge head. Both species are grayish to brown, with sparse, coarse body hair. The trunk is used for breathing, drinking, and reaching for food. Elephants eat grasses, leaves, and fruit. The African elephant (Loxodonta africana), of sub-Saharan Africa, is the largest living land animal, weighing up to 16,500 lbs (7,500 kg) and standing 10-13 ft (3-4 m) tall at the shoulder. The Indian elephant (Elephas maximus), of the Indian subcontinent and South Asia, weighs about 12,000 lbs (5,500 kg) and stands about 10 ft (3 m) tall. Both species live in habitats ranging from thick jungle to savanna, in small family groups led by old cows. Most bulls live in bachelor herds. Elephants migrate seasonally. They may eat more than 500 lbs (225 kg) of vegetation daily. The Indian elephant is considered endangered and the African elephant threatened.
