23-10-2019 BIOPARC, VALENCIA - AFRICAN ELEPHANT (Loxodonta africana)


African elephants are members of the genus Loxodonta comprising two living elephant species, the African bush elephant (L. africana) and the smaller African forest elephant (L. cyclotis). Both are social herbivores with grey skin, but differ in the size and colour of their tusks and in the shape and size of their ears and skulls.

Both species are considered at heavy risk of extinction on the IUCN Red List; as of 2021, the bush elephant is considered endangered and the forest elephant is considered critically endangered. They are threatened by habitat loss and fragmentation, and poaching for the illegal ivory trade is a threat in several range countries as well.

Loxodonta is one of two extant genera of the family Elephantidae. The name refers to the lozenge-shaped enamel of their molar teeth. Fossil remains of Loxodonta species have been excavated in Africa, dating to the Middle Pliocene.


African elephants are distributed in Sub-Saharan Africa, where they inhabit Sahelian scrubland and arid regions, tropical rainforests, mopane and miombo woodlands. African forest elephant populations occur only in Central Africa.

15-4-2018 CHOBE RIVER, NAMIBIA - AFRICAN ELEPHANT (Loxodonta africana)


The African bush elephant (Loxodonta africana), also known as the African savanna elephant, is a species of elephant native to sub-Saharan Africa. It is one of three extant elephant species and, along with the African forest elephant, one of two extant species of African elephant. It is the largest living terrestrial animal, with fully grown bulls reaching an average shoulder height of 3.04–3.36 metres (10.0–11.0 ft) and a body mass of 5.2–6.9 tonnes (11,000–15,000 lb); the largest recorded specimen had a shoulder height of 3.96 metres (13.0 ft) and an estimated body mass of 10.4 tonnes (23,000 lb). The African bush elephant is characterised by its long prehensile trunk with two finger-like processes; a convex back; large ears which help reduce body heat; and sturdy tusks that are noticeably curved. The skin is grey with scanty hairs, and bending cracks which support thermoregulation by retaining water.


The African bush elephant inhabits a variety of habitats such as forests, grasslands, woodlands, wetlands and agricultural land. It is a mixed herbivore feeding mostly on grasses, creepers, herbs, leaves, and bark. The average adult consumes about 150 kg (330 lb) of vegetation and 230 L (51 imp gal; 61 US gal) of water each day. A social animal, the African bush elephant often travels in herds composed of cows and their offspring. Adult bulls usually live alone or in small bachelor groups. During the mating season, males go through a process called musth; a period of high testosterone levels and heightened aggression. For females, the menstrual cycle lasts three to four months, and gestation around 22 months, the longest of any mammal.

African elephants are distributed in Sub-Saharan Africa, where they inhabit Sahelian scrubland and arid regions, tropical rainforests, mopane and miombo woodlands. African forest elephant populations occur only in Central Africa.

The range of African elephants (Loxodonta africana) is patchily distributed across central and southern Africa in the Ethiopian Region. Remnant populations exist as far northwest as Guinea-Bissau and as far northeast as Ethiopia. Disjunct populations exist southward into northern South Africa, and include contiguous populations in Gabon, Tanzania, Botswana, and Zambia. Once present in Burundi, Gambia, and Mauritania, they've now been extirpated from those countries. These elephants were extirpated from Swaziland, as well, but have been re-introduced here in recent years.

African elephants are found in many habitats of Africa such as savannas, rain forests, woodlands, scrub forests, occasionally deserts, and beaches. However, due to poaching threats protected sanctuaries are their main habitats. Within these sanctuaries, these elephants will inhabit areas that have sources of water and abundant vegetation for foraging. Across these habitats, the elevation level ranges from sea level (0 meters) to 4000 meters.

17-4-2018 CHOBE RIVER, BOTSWANA - AFRICAN ELEPHANT (Loxodonta africana)


The African bush elephant (Loxodonta africana) is one of two living African elephant species. It is the largest living terrestrial animal and is distributed across 37 African countries. Since 2021, it has been listed as Endangered on the IUCN Red List. It is threatened foremost by habitat destruction, and in parts of its range also by poaching for meat and ivory.


Savanna elephants live in a rather complex social hierarchy. These animals gather into family units, consisting of about 10 females and their offspring. Reaching maturity, male calves usually leave the family unit, forming bachelor herds or living solitarily. As a general rule, males socialize with these family groups only when mating. Meanwhile, several family herds may gather together, making up a 'clan'. Each clan is dominated by a female matriarch and can consist of as many as several hundred elephants. African bush elephants are very careful and protective animals. Allomothering is a common practice in this species: females can raise calves of other females of their herd. They protect and care for the calves of the herd, while all adults are sleeping. If a calf strays too far, these allomothers are responsible for retrieving the baby. These active animals are constantly on the move. These elephants forage during the daytime hours, wandering the home range of their herd. Savanna elephants freely communicate with conspecifics both verbally and non-verbally.


Savanna elephants have a polygynous mating system, where males are constantly in search of breeding females. They breed throughout the year with peak periods, occurring during the rainy seasons. When mating, males usually stay less than a few weeks with each female and her herd. The gestation period lasts as long as 2 years, yielding a single baby (rarely - twins), which is nursed for about 2 years. The calf then continues to live under the protection of the entire herd until 6 years old, when the young elephant is able to live independently. Males of this species are reproductively mature after 20 years old, whereas females are mature after 10-11 years, being most reproductive at 25-45 years old.

The African bush elephant (Loxodonta africana) is one of two living African elephant species. It is the largest living terrestrial animal and is distributed across 37 African countries. Since 2021, it has been listed as Endangered on the IUCN Red List. It is threatened foremost by habitat destruction, and in parts of its range also by poaching for meat and ivory.


The African bush elephant has grey skin with scanty hairs. Its large ears cover the whole shoulder and can grow as large as 2 m × 1.5 m (6 ft 7 in × 4 ft 11 in). Its large ears help to reduce body heat; flapping them creates air currents and exposes large blood vessels on the inner sides to increase heat loss during hot weather. The African bush elephant's ears are pointed and triangular-shaped. Its occipital plane slopes forward. Its back is shaped markedly concave. Its sturdy tusks are curved out and point forward. The trunk is a prehensile extension of the upper lip and nose. Short tactile hair grows on the trunk, which has two finger-like processes on the tip. This highly sensitive organ is innervated primarily by the trigeminal nerve and is thought to be manipulated by about 40,000-60,000 muscles. Because of this muscular structure, the trunk is so strong that elephants can use it for lifting about 3% of their own body weight.


They use it for smelling, touching, feeding, drinking, dusting, sound production, loading, defending, and attacking. Both sexes have tusks, which erupt when they are 1-3 years old and grow throughout life. Tusks grow from deciduous teeth known as tushes that develop in the upper jaw and consist of a crown, root, and pulpal cavity, which are completely formed soon after birth. Tushes reach a length of 5 cm (2.0 in). The tusks of males grow faster than the tusks of females.


African bush elephants occur in Sub-Saharan Africa including Uganda, Kenya, Tanzania, Botswana, Zimbabwe, Namibia, Zambia, and Angola. They move between a variety of habitats, including forests, dry and seasonally flooded grasslands, woodlands, shrubland, and wetlands to mountain slopes. In Mali and Namibia, they also inhabit desert and semi-desert areas.
