African Forest Elephant:Common Names: Pygmy ElephantGenus: LoxodontaSpecies: cyclotis
It was always thought that there were two species of elephant in the world; the African savanna elephant,( Loxodonta africana) and the Asian elephant, (Elephas maximus). But now, through DNA testing, it has been discovered that there is a third species; the African forest elephant.
When a DNA identification system was set up to trace where poached ivory was coming from, scientists found that the African elephants consisted of two very different species. They expected slight variations in the genetic makeup of the savanna elephant, but were surprised to discover the two different species.
The new species, the forest elephant, was considered to be a subspecies of the African elephant, and was known as Loxodonta africana cyclotis. That means scientists thought that, although the elephants had adapted to their forest habitat, they were still savanna elephants. But DNA evidence shows that about 2.5 million years ago two genetically different strains of elephants evolved in Africa. The forest elephant, now known as Loxodonta cyclotis,found its niche in the equatorial forests of central and western Africa. Here they have lived hidden from view and practically forgotten.
Some scientists consider the two species as different as lions are from tigers, or horses are from zebras. Genetically the difference between the two species of elephant is more than half as big as the differences between the African elephant and the Asian elephant, or 58%.
When you think of the African elephant you probably picture the savanna elephant. It is a huge animal, standing almost 12 feet tall at the shoulders. It has large ears that come to a point at the bottom. The tusks are long and slightly curved. They live on large, dry grasslands with a few thorny acacias dotting the plains.
The forest elephants look very different from savanna elephants. For one thing, they are smaller and stockier than savanna elephants. Forest elephant males only get to be about 8 feet in height while large savanna elephants can reach 13 feet. Their ears are rounded and their tusks are straight and thin with a pinkish tinge to the ivory. The lower jaw is longer, giving the forest elephant a long, narrow face. Forest elephants also live in smaller family groups. Forest elephants are also darker than savanna elephants.
