Loxodonta africana
MAMMAL Order Proboscidea
Description Largest living land
mammal. 20-24 feet long, 9-12 feet high at shoulder, weighs up to 17,000 pounds;
males larger. Color gray, but varies with soil color since elephants wallow and
throw dirt on themselves. Thick, craggy skin sparsely covered with coarse hair.
Back dips in the middle, large ears, trunk with two ˇ°fingers.ˇ± Four front toes,
three hind toes.
Range Africa, south of the
Sahara.
Status This species was
petitioned for uplisting from threatened to endangered in 1989, but the U.S.
Fish and Wildlife Service decided in 1992 to continue to classify it as
threatened. Justification was based upon a reduction in the number of illegally
killed elephants after the 1989 ivory trade ban by the Convention on
International Trade in Endangered Species. Import of African ivory into the
United States is prohibited. Lincoln Park Zoo is a member of the Elephant
Species Survival Plan.
Habitat Savanna grassland and
forests.

Niche Herbivorous: eats
mainly grasses; leaves, woody parts of trees and shrubs, flowers, fruits and
roots are also eaten. Adults need about 330 pounds of food and about 22 gallons
of water each day. Young preyed upon by hyenas and lions. Herds follow the same
paths over several generations, resulting in wide cuts through the bush. Bull
and cow herds live apart; matriarch herds exhibit complex social behavior.
Life History Reproductive cycle
corresponds to seasonal food and water supplies. Bulls enter an aggressive
condition called ˇ°musthˇ± during rutting season. Gestation 22 months; birth
weight about 265 pounds. Infant suckles with mouth 3-4 years. Maturity at 10
years+. Life span in the wild 15-30 years, in captivity 60-80 years. African
elephants do not have a continuous history as beasts of burden but have been
trained and used as such.
