African forest elephant
The African forest elephant (''Loxodonta cyclotis'') is a forest-dwelling species of elephant found in the Congo Basin. It is the smallest of the three extant species of elephant, but also the third-largest living terrestrial animal. The African forest elephant and the African bush elephant were considered to be one species until genetic studies showed that their relationship is distant.〔
== Classification ==
The African forest elephant was once considered to be a subspecies, ''Loxodonta africana cyclotis'', of the African elephant, together with the African bush elephant. DNA tests, however, indicated the two populations were much more genetically diverse than previously believed.〔 In 2010, a genetic study confirmed they are separate species which diverged from each other an estimated two to seven million years ago.〔〔
The disputed pygmy elephants of the Congo Basin, often assumed to be a separate species (''Loxodonta pumilio'') by cryptozoologists, are probably forest elephants whose diminutive size or early maturity is due to environmental conditions.〔
