African forest elephant range |
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 still the third-largest living terrestrial animal. The African forest elephant and the African bush elephant, L. africana, were considered to be one species until genetic studies indicated that they separated an estimated 2–7 million years ago. Due to a slower birth rate, the forest elephant takes longer to recover from poaching, which caused its population to fall by 65% from 2002 to 2013.
In 2016, DNA sequence analysis showed that L. cyclotis is more closely related to the extinct European straight-tusked elephant, Palaeoloxodon antiquus, than it is to L. africana.
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 that 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. Still, many governmental (e.g. USFWS) and non-governmental agencies (e.g. IUCN) consider the forest elephant to be a subspecies for regulatory and conservation purposes.
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.
These forest-dwelling elephants are smaller and darker than their savanna relatives, the bush elephants, and have smaller and more rounded ears. Compared to the bush elephant, the African forest elephant has a longer, narrower mandible. Its tusks are straighter and harder and have a more yellow or brownish color. These strong tusks are used to push through the dense undergrowth of their habitat and bull elephants (mature males) are sometimes known to have exceptionally long tusks that reach almost to the ground. The species normally has five toenails on the forefoot and four on the hindfoot, like the Asian elephant but unlike the African bush elephant which normally has four toenails on the forefoot and three on the hindfoot. They also protect themselves from the sun by using sand.
