The Borneo Pygmy Elephant
The Borneo pygmy elephant (scientific name elephas maximus borneensis) is a subspecies of elephant that inhabits the forests of Borneo. It is the smallest of the subspecies of elephant that live in Asia, standing between 8.2 and 9.8 feet tall. It also has the longest tail (which is so long that it sometimes drags on the ground as it walks), largest ears, and straightest tusks of these subspecies. This is due to being isolated from the other two subspecies (the Asian elephant and the Sumatran elephant) for about 300,000 years. In addition, it is also more gentle-natured than the Asian elephant, and it has a plump stomach and an eternally young face.
The Borneo pygmy elephant is classified as an Endangered species. It is this close to becoming extinct because its habitat is being converted into commercial plantations. Because of this, the World Wildlife Fund's (WWF's) effort to save it consists of working with the owners and managers of these plantations to create reforested wildlife corridors for it.
