African Elephant

About the african elephant

The African elephant covered here is the African bush elephant (Loxodonta africana), one of two living species in the genus Loxodonta — the other, the smaller African forest elephant, lives only in Central and West Africa. The genus name comes from the Greek for "slanting tooth," a reference to the lozenge-shaped enamel pattern on the molars, which is distinct from the rounder pattern in Asian elephant teeth. The two African species differ in more than just size: their tusks vary in shape and color, and their ears and skulls differ as well. Genetic evidence puts their divergence somewhere between 2.6 and 5.6 million years ago, though the two have hybridized at points where savanna and forest habitat meet.

The African bush elephant is, by a wide margin, the largest land animal on Earth. Under good conditions, fully grown females stand 2.47 to 2.73 m (8 ft 1 in–8 ft 11 in) at the shoulder and weigh 2.6 to 3.5 tons; mature bulls stand 3.04 to 3.36 m (10–11 ft) and weigh 5.2 to 6.9 tons. The largest bull ever recorded stood 3.96 m (13 ft) at the shoulder and is estimated to have weighed 10.4 tons. Its back is distinctly concave, in contrast to the nearly straight back of the smaller forest elephant.

Grey, folded skin up to 30 mm (1.2 in) thick covers the body, sparsely covered in dark brown to black bristled hair. The trunk — a muscular extension of the upper lip and nose, controlled by an estimated 40,000 to 60,000 muscles and richly supplied by the trigeminal nerve — is strong enough to lift roughly 3% of the elephant's own body weight, and versatile enough to serve as a hand, a hose, a snorkel, and a communication tool all at once. It ends in two finger-like tips, versus the single tip on an Asian elephant's trunk. Large ears do double duty as a cooling system: flapping them generates airflow and exposes blood vessels close to the surface on the inner ear, shedding heat in hot conditions.

Both males and females grow tusks, which start as deciduous "tush" teeth and are replaced by permanent tusks around a calf's first year. They're made of dentin, denser toward the outer edge, weigh 23 to 45 kg (51–99 lb), run 1.5 to 2.4 m (5–8 ft) long, curve forward, and keep growing for the elephant's entire life. Elephants use them to dig for roots, strip bark, fight during the breeding season, and defend against predators. Molars work differently — an elephant has four in use at a time, each weighing about 5 kg (11 lb) and measuring roughly 30 cm (12 in), and as the front pair wears down and breaks apart, the back pair shifts forward to replace it. An elephant goes through this replacement cycle four to six times over its life; once the last set is gone, at around 40 to 60 years old, it typically starves, a common cause of death in the wild.

Behavior and diet

African elephants live in tight family units built around an older matriarch, typically made up of her adult daughters and their young along with subadult sons. When separate family units come into contact regularly, they can form larger kinship or bond groups. Males head out on their own after puberty and tend to form close bonds with other males; contrary to the old idea that bulls are simply solitary once grown, more recent research suggests older bulls hold onto ecological knowledge — where to find food and water — that benefits younger males who travel with them. Bulls typically return to a female herd only to breed or socialize and don't provide direct parental care, functioning instead as a kind of general mentor figure to younger males.

Communication runs on infrasonic calls, pitched below the range of human hearing, which let elephants recognize and coordinate with each other across long distances — both males and females can distinguish among hundreds of distinct calls. Elephants aren't strictly territorial, but they do show patterns in how they use space, shaped by social structure, season, climate, and food and water availability; herds can range over several hundred to several thousand square kilometers and follow established migratory routes that link habitat patches together. Among adult males, dominance is closely tied to musth, a periodic state marked by a surge in testosterone, heightened aggression, and a set of visible signals — temporal gland secretion, urine dribbling, particular postures — that usually settle disputes over access to females without a physical fight. When those signals fail, direct confrontations involving tusking and pushing can follow, with older, larger, musth males typically dominant over younger or non-musth rivals.

As feeders, African elephants are generalist herbivores, taking leaves, grasses, bark, and fruit, and leaning more heavily on woody vegetation during the dry season. They pluck leaves and tear branches using their tusks, doing significant damage to trees in the process, and ferment their food in an enlarged hindgut that allows for very large daily intake and digestion of tough plant parts — fibrous stems, bark, and roots included. That digestive setup also makes elephants highly effective seed dispersers: because they range widely and their digestive tract doesn't destroy seeds, a single pile of elephant dung can contain seeds from ten or more tree species, sometimes upward of 50, spreading plant diversity across large areas and helping seeds germinate without relying on wind.

African elephants are also considered highly intelligent, with a large, deeply folded neocortex — the elephant brain, at just over 5 kg (11 lb), is the largest of any land animal, with a cortex carrying about as many neurons as a human brain. Documented behavior includes grief responses, learning, mimicry, play, apparent humor, altruism, tool use, compassion, cooperation, and self-awareness — a range of traits that puts elephants in the same conversation as great apes and dolphins when it comes to animal cognition.

Range and habitat

African elephants are distributed across sub-Saharan Africa, where they occupy Sahelian scrubland, arid regions, tropical rainforest, and mopane and miombo woodland. The forest elephant is restricted to Central and West Africa specifically, while the bush elephant occupies a much broader range across the rest of sub-Saharan Africa's savanna and scrub habitats.

Conservation status

As of 2021, the African bush elephant is classified as Endangered, while its smaller relative, the African forest elephant, is Critically Endangered. Both species face the same core pressures: habitat loss and fragmentation, combined with poaching driven by the illegal ivory trade across a number of range countries. Beyond naming these two threats, further detail on protection programs isn't given here, but the split IUCN status between the two species — with the smaller forest elephant in more acute danger — reflects how differently poaching and deforestation have hit each population.
