It is now extinct in these areas,[145] and the current range of Asian elephants is highly fragmented. [174], Elephants can exhibit bouts of aggressive behaviour and engage in destructive actions against humans. In southern India, elephant populations may contain family groups, bond groups and possibly clans. [162], One of the earliest references to war elephants is in the Indian epic Mahabharata (written in the 4th century BC, but said to describe events between the 11th and 8th centuries BC).

[145], The poaching of elephants for their ivory, meat and hides has been one of the major threats to their existence. The back of the skull is flattened and spread out, creating arches that protect the brain in every direction. By contrast, small mammals such as rodents develop gigantism in these conditions. The number of premolars, incisors and canines decreased. The skull grew larger, especially the cranium, while the neck shortened to provide better support for the skull.

[149], The ban allowed the elephant to recover in parts of Africa. [66] During locomotion, the cushion pads expand and contract, and reduce both the pain and noise that would come from a very heavy animal moving. It is still dependent on its mother and keeps close to her. [35], Elephants are the largest living terrestrial animals. [151], Other threats to elephants include habitat destruction and fragmentation. When a cow has mated, her family may produce calls of excitement known as the "mating pandemonium".

[68] Elephants have a unique organ, the temporal gland, located in both sides of the head. As a piece of living tissue, a tusk is relatively soft; it is as hard as the mineral calcite. The former is typical of bulls in dense forests. [127] Infrasonic calls are important, particularly for long-distance communication,[123] in both Asian and African elephants. Their habit of uprooting trees and undergrowth can transform savannah into grasslands; when they dig for water during drought, they create waterholes that can be used by other animals. It has a double-pointed apex, an unusual trait among mammals. Elephants possess several adaptations suited for seismic communication. Vocal production mechanisms at certain frequencies are similar to that of humans and other mammals and the laryngeal tissues are subjected to self-maintained oscillations. Adults and most of the other young will gather around the newborn, touching and caressing it with their trunks. Although tough, an elephant's skin is very sensitive. [74] Females have also been observed with secretions from the temporal glands. A newly developed tusk has a smooth enamel cap that eventually wears off. The skull proportions between species is markedly different. It still needs its mother for nutrition and protection from predators for at least another year. Safe search; On. Male Asian elephants are usually about 261–289 cm (8 ft 7 in–9 ft 6 in) tall at the shoulder and 3.5–4.6 t (3.9–5.1 short tons) whereas females are 228–252 cm (7 ft 6 in–8 ft 3 in) tall at the shoulder and 2.3–3.1 t (2.5–3.4 short tons). Births tend to take place during the wet season. The Asian elephant also has dorsal bumps on its head and some patches of depigmentation on its skin.

[2], Elephants belong to the family Elephantidae, the sole remaining family within the order Proboscidea which belongs to the superorder Afrotheria. [13][14][15] In 2017, DNA sequence analysis showed that L. cyclotis is more closely related to the extinct Palaeoloxodon antiquus, than it is to L. africana, possibly undermining the genus Loxodonta as a whole. Spring-like kinetics could explain the difference between the motion of elephants and other animals. [172] Some trainers have tried to train elephants without the use of physical punishment. [62] They appear to have a sesamoid, an extra "toe" similar in placement to a giant panda's extra "thumb", that also helps in weight distribution. [8] Elephants and sirenians are further grouped in the clade Tethytheria. The long bones of the limbs have cancellous bone in place of medullary cavities. How long will it take to be delivered? [191], Elephants have been the subject of religious beliefs. [12] Both kinds of elephant were traditionally considered to be the same species Loxodonta africana, but molecular studies have affirmed their status as separate species. [89] Elephants tend to have high numbers of parasites, particularly nematodes, compared to other herbivores. The trunk is used for breathing, bringing food and water to the mouth, and grasping objects. When fighting, they are used to attack and defend, and to protect the trunk.

In a population in southern India, males first enter musth at the age of 15, but it is not very intense until they are older than 25. Elephants typically have grey skin, but African elephants look brown or reddish after wallowing in coloured mud.

By 1989, the population was estimated to be 609,000; with 277,000 in Central Africa, 110,000 in eastern Africa, 204,000 in southern Africa, and 19,000 in western Africa. [162], Overall, elephants owed their initial successes to the element of surprise and to the fear that their great size invoked.
