African bush elephant

The African bush elephant (Loxodonta africana), also known as the African savanna elephant, is the largest living terrestrial animal. It is native to sub-Saharan Africa and is characterized by its long, prehensile trunk with two finger-like processes, a concave back, large ears that aid in reducing body heat, and noticeably curved tusks. Its skin is grey with scanty hairs and features bending cracks that assist in thermoregulation by retaining water.

Habitat and Distribution

African bush elephants inhabit a diverse range of environments, including subtropical and temperate forests, dry and seasonally flooded grasslands, woodlands, wetlands, and agricultural lands. They can be found from sea level to mountain slopes across sub-Saharan Africa, with significant populations in countries such as Botswana, Zimbabwe, Namibia, Zambia, Kenya, and Tanzania. In some regions, like Mali and Namibia, they also inhabit desert and semi-desert areas.

Physical Characteristics

Fully grown bulls typically reach an average shoulder height of 3.04–3.36 meters (10.0–11.0 ft) and weigh between 5.2–6.9 tonnes (5.7–7.6 short tons). The largest recorded specimen had a shoulder height of 3.96 meters (13.0 ft) and an estimated body mass of 10.4 tonnes (11.5 short tons). Mature females are smaller, averaging about 2.60 meters (8 ft 6 in) at the shoulder and weighing around 3.0 tonnes (3.3 short tons). Their large ears, which can be as big as 2 meters by 1.5 meters, are pointed and triangular and help dissipate heat. Both sexes possess large, curved tusks that continue to grow throughout their lives.

Diet and Daily Consumption

These elephants are mixed herbivores, consuming a diet that varies seasonally and by habitat. Their food consists mainly of grasses, creepers, herbs, leaves, and bark. They are capable of consuming up to 150 kg (330 lb) of vegetation and 230 l (61 US gal) of water each day. To supplement minerals, they visit mineral-rich water holes, termite mounds, and salt licks. Their habit of uprooting trees can significantly alter the landscape, transforming woodlands into grasslands.

Social Structure and Behavior

The social organization is centered around family units, mostly composed of adult cows, their daughters, and young sons, led by a matriarch. Adult males typically live solitary lives or form small bachelor groups. These herds cooperate in finding food and water, defending themselves, and caring for the young through a practice known as allomothering. Communication occurs through vocalizations such as rumbles, trumpets, squeals, and screams, with infrasonic rumbles used for long-distance communication. Tactile communication is also vital, with elephants using their trunks for greetings and reassurance.

Reproduction and Lifespan

The gestation period for African bush elephants is approximately 22 months, the longest of any mammal. Calves are born weighing between 100 and 120 kg (220 and 260 lb) in captivity and can stand within an hour of birth. Cows lactate for about 4.8 years. While specific lifespan data is not detailed, elephants reach their maximum stature in their late 20s to 40s, suggesting a long lifespan.

Conservation Status and Threats

As of 2021, the African bush elephant is listed as Endangered on the IUCN Red List. The primary threats to their survival are habitat destruction and fragmentation, largely driven by human population growth, and poaching for ivory and meat. Conservation efforts include increased penalties for poaching and improved law enforcement, alongside strategies to manage human-wildlife conflict.
