African elephants are the elephants of the genus Loxodonta (Greek for 'oblique-sided tooth'), consisting of two extant species: the African bush elephant and the smaller African forest elephant. Loxodonta is one of the two existing genera in the family Elephantidae.
Fossil members of Loxodonta have been found only in Africa, where they developed in the middle Pliocene.
One of the species of African elephant, the bush elephant, is the largest living terrestrial animal, while the forest elephant is the third largest. Their thickset bodies rest on stocky legs, and they have concave backs. Their large ears enable heat loss. The upper lip and nose form a trunk. The trunk acts as a fifth limb, a sound amplifier and an important method of touch. African elephants' trunks end in two opposing lips, whereas the Asian elephant trunk ends in a single lip. In L. africana, males stand 3.2–4.0 m (10–13 ft) tall at the shoulder and weigh 4,700–6,048 kg (10,360–13,330 lb), while females stand 2.2–2.6 m (7–9 ft) tall and weigh 2,160–3,232 kg (4,762–7,125 lb); L. cyclotis is smaller with male shoulder heights of up to 2.5 m (8 ft).
The largest recorded individual stood four metres (13.1 ft) to the shoulders and weighed 10 tonnes (10 long tons; 11 short tons).
Teeth
Elephants have four molars; each weighs about 5 kg (11 lb) and measures about 30 cm (12 in) long. As the front pair wears down and drops out in pieces, the back pair shifts forward, and two new molars emerge in the back of the mouth. Elephants replace their teeth four to six times. At about 40 to 60 years of age, the elephant no longer has teeth and will likely die of starvation, a common cause of death. The enamel plates of the molars are fewer in number than in Asian elephants.
Their tusks are firm teeth; the second set of incisors become the tusks. They are used for digging for roots and stripping the bark off trees for food, for fighting each other during mating season, and for defending themselves against predators. The tusks weigh from 23–45 kg (51–99 lb) and can be from 1.5–2.4 m (5–8 ft) long. Unlike Asian elephants, both male and female African elephants have tusks. They are curved forward and continue to grow throughout the elephant's lifetime.
African elephants can be found in Eastern, Southern and West Africa, either in dense forests, mopane and miombo woodlands, Sahelian scrub or deserts.
