African elephant

African elephants are elephants of the genus Loxodonta, from Greek. The genus consists of two extant species: the African bush elephant and the smaller African forest elephant. Loxodonta is one of two existing genera of the family, Elephantidae. Fossil remains of Loxodonta have been found only in Africa, in strata as old as the middle Pliocene.
One 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.[4] 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) at the shoulders and weighed 10 tonnes (10 long tons; 11 short tons).
African elephants are highly intelligent, and they have a very large and highly convoluted neocortex, a trait they share withhumans, apes and some dolphin species. They are amongst the world's most intelligent species. With a mass of just over 5 kg (11 lb), elephant brains are larger than those of any other land animal, and although the largest whales have body masses twenty-fold those of a typical elephant, whale brains are barely twice the mass of an elephant's brain. The elephant's brain is similar to that of humans in terms of structure and complexity. For example, the elephant's cortex has as many neurons as that of a human brain, suggesting convergent evolution.
Elephants exhibit a wide variety of behaviors, including those associated with grief, learning, allomothering, mimicry, art, play, a sense of humor, altruism, use of tools, compassion, cooperation, self-awareness, memory and possibly language. All point to a highly intelligent species that is thought to be equal with cetaceans, and primates.
