African elephants are the world's largest land animals. The biggest can be up to 7.5m long, 3.3m high at the shoulder, and 6 tonnes in weight.
The trunk is an extension of the upper lip and nose and is used for communication and handling objects, including food. African elephants have two opposing extensions at the end of their trunks, in contrast to the Asian elephant, which only has one.
Tusks, which are large modified incisors that grow throughout an elephant's lifetime, occur in both males and females and are used in fights and for marking, feeding, and digging.
The other notable feature of African elephants is their very large ears, which allow them to radiate excess heat.
Two subspecies, two homes
There are two subspecies – the larger savannah elephant (Loxodonta africana africana), which roams grassy plains and woodlands, and the smaller forest elephant (Loxodonta africana cyclotis), which lives in the equatorial forests of central and western Africa.
Savannah elephants are larger than forest elephants, and their tusks curve outwards. In addition to being smaller, forest elephants are darker and their tusks are straighter and downward pointing.
Social structure
The complex social structure of elephants is organized around a system of herds composed of related females and their calves. Males usually live alone but sometimes form small groups with other males.
In the savannah subspecies, each family unit usually contains about 10 individuals, although several family units may join together to form a 'clan' consisting of up to 70 members led by a female. Forest elephants live in smaller family units.
Life cycle
Usually, a single calf is born after a gestation period of 22 months. Young elephants wean after 6 to 18 months, although they may continue nursing for over 6 years.
Male elephants leave their natal group at puberty and tend to form much more fluid alliances with other males.
Elephants live up to around 70 years, with females mostly fertile between 25 and 45. Males need to reach 20 years of age in order to successfully compete for mating.
African elephants mainly eat leaves and branches of bushes and trees, but also eat grasses, fruit, and bark.
