Elephants are the largest existing land animals. Three living species are currently recognised: the African bush elephant, the African forest elephant, and the Asian elephant (of which it contains four subspecies (Bornean, Sri Lankan, Sumatran & Indian)). They are the only surviving members of the family Elephantidae and the order Proboscidea. The order was formerly much more diverse during the Pleistocene, but most species became extinct during the Late Pleistocene epoch. Distinctive features of elephants include a long proboscis called a trunk, tusks, large ear flaps, pillar-like legs, and tough but sensitive skin. The trunk is used
for breathing and is prehensile, bringing food and water to the mouth, and grasping objects. Tusks, which are derived from the incisor teeth, serve both as weapons and as tools for moving objects and digging. The large ear flaps assist in maintaining a constant body temperature as well as in communication. African elephants have larger ears and concave backs, whereas Asian elephants have smaller ears, and convex or level backs.
Elephants are scattered throughout sub-Saharan Africa, South Asia, and Southeast Asia and are found in different habitats, including savannahs, forests, deserts, and marshes. They are herbivorous, and they stay near water when it is accessible. They are considered to be keystone species, due to their impact on their environments. Elephants have a fission–fusion society, in which multiple family groups come together to socialise. Females (cows) tend to live in family groups, which can consist of one female with her calves or several related females with offspring. The leader of a female group, usually the oldest cow, is known as the matriarch.

Males (bulls) leave their family groups when they reach puberty and may live alone or with other males. Adult bulls mostly interact with family groups when looking for a mate. They enter a state of increased testosterone and aggression known as musth, which helps them gain dominance over other males as well as reproductive success. Calves are the centre of attention in their family groups and rely on their mothers for as long as three years. Elephants can live up to 70 years in the wild. They communicate by touch, sight, smell, and sound; elephants use infrasound and seismic communication over long distances. Elephant intelligence has been compared with that of primates and cetaceans. They appear to have self-awareness, and possibly show concern for dying and dead individuals of their kind.
African bush elephants and Asian elephants are listed as endangered and African forest elephants as critically endangered by the International Union for Conservation of Nature (IUCN). One of the biggest threats to elephant populations is the ivory trade, as the animals are poached for their ivory tusks. Other threats to wild elephants include habitat destruction and conflicts with local people. Elephants are used as working animals in Asia. In the past, they were used in war; today, they are often controversially put on display in zoos, or employed for entertainment in circuses. Elephants have an iconic status in human culture, and have been widely featured in art, folklore, religion, literature, and popular culture.
The Magnificent Elephant: A Taxonomic Profile The Elephant is the three surviving elephant species alongside the larger Woolly Mammoth. Elephants inhabit tropical forests and grasslands in parts of Sub-Saharan Africa, South and Southeast Asia. As the largest existing land mammal, this iconic species holds an important role in both ecosystems and human culture. Their taxonomic classification reflects their evolutionary relationship to other elephants.
Kingdom Animalia Elephants belong to kingdom Animalia as complex, multicellular eukaryotic organisms. All animals share key characteristics like heterotrophic modes of nutrition, lacking cell walls, and lacking photosynthetic ability. Elephants require organic matter for sustenance.
Phylum Chordata Placement in phylum Chordata is based on the presence of several key features. Elephants possess a notochord, dorsal hollow nerve cord, pharyngeal gill slits, post-anal tail, and endoskeleton. These characteristics categorize them as vertebrates.
Class Mammalia As mammals, elephants are endothermic, have hair, produce milk through mammary glands to feed their young, and have neocortex brain regions. They birth live young and possess specialized teeth. All qualities of class Mammalia.
Order Proboscidea This order contains elephants and their extinct proboscidean relatives. Elephants are placed here due to anatomical features adapted for their lifestyle, especially the muscular proboscis known as the trunk. Other shared traits include tusks and large ear flaps.
Family Elephantidae The elephant family consists of Asian elephants, African elephants, and mammoths. Key unifying features are the long proboscis, tusks, large ears, pillar-like legs, and bulky body. Elephants are the only surviving Elephantidae species.
Genus Varies Within Elephantidae, elephants comprise various genuses. There are two genuses for elephants. the Loxodonta genus and Elephas genus containing African bush elephants, African Forest elephants and Asian elephants. Elephants are morphologically and geographically distinct.
Species Varies The species epithet Maximus, cyclotis and Africana refers to the large body size of Elephants combination with both the African and asian elephants height (27 ft in total). Three species are recognized: L. Africana/E. Africanus, L. cyclotis/E. cyclotis and E. maximus. They vary slightly in size and geographic distribution.
Anatomy and Morphology Trunk The most distinctive feature of Elephants is the elongated, prehensile proboscis known as the trunk. Formed from the upper lip and nose, it averages 1.5-2 m long with over 100,000 muscle units. The trunk is used for breathing, feeding, communication, sensation, and grasping objects. The two finger-like tips are covered in fine hairs and rosette-like prints unique to each individual.
Tusks Tusks are modified upper incisors that grow throughout an elephant's life. Elephant tusks are relatively small, averaging just 1-1.5 m in males. Only some males have large tusks, while female tusks are barely visible. Tusks are used for digging, lifting, defense, and display.
Ears Elephants have very large ears. These help regulate body temperature through evaporative cooling as blood circulates through the many small blood vessels. Ears also aid hearing and communication.
Body Characteristics Elephants exhibit typical elephant body morphology. Adults stand 8 m tall at the shoulder and weigh 7,000-10'000 kg. Their barrel-shaped body has a high domed back. Thick pillar-like legs support the enormous bulk. Tail hair is sparse and coarse. Skin color is grayish with pink patchy areas.
Habitat and Distribution Elephants historically ranged from Africa to West Asia to Southeast Asia. Today fragmented populations exist from India to Indonesia, with the largest in Africa. They inhabit diverse ecosystems including tropical forests, grasslands, and scrublands. Ideal habitat provides abundant plant food and access to water sources.
Behavior and Lifestyle Elephants live in matriarchal family groups of related females and offspring. Adult males roam alone or form loose associations. Their social structure revolves around the experienced matriarch. Vocalizations, scent markings, and infrasound aid group cohesion and communication. elephants are highly intelligent with complex cognitive abilities.
Breeding and Reproduction Sexual maturity occurs around 10 years old. After a 22-month gestation, a single calf is born weighing 100-150 kg. Calves are dependent for 3-5 years. Interbirth intervals are typically 4-5 years. Elephants are long-lived, surviving 60-70 years or more in the wild.
Diet and Feeding Elephants are generalist megaherbivores, consuming over 100 kg of plant material daily. Using their trunk, they feed on grasses, tree leaves and bark, shrubs, fruit, palms, and bamboo. Their wide-ranging diet provides flexibility in varied habitats. Daily activities revolve around finding suitable feeding areas.
Threats and Conservation Three species of elephant are recognized. The African bush elephant elephant (L. Africana) is the most populous. The African Forest elephant (L. cyclotis) and Asian elephant (E. Maximus) are endangered primarily due to habitat loss. African bush elephants and Asian elephants are endangered whereas African Forest elephants are critically endangered by poaching and human-elephant conflict. Protected areas and anti-poaching efforts are critical for conservation.
In summary, the taxonomy of the elephant highlights its relationship to other proboscidean species over evolutionary timescales. Current knowledge indicates it is the sole surviving elephant species in Africa and Asia. Efforts to protect this iconic keystone mammal and its diminishing habitat are crucial to preserving the magnificent Elephant for future generations.
