Pygmy elephants live in both Africa[1] and Asia.[2][3][4] The African pygmy elephant, formerly described as "Loxodonta pumilio", is currently considered to be a tiny morph of the African forest elephant (L. cyclotis).[1] The Borneo elephant (Elephas maximus borneensis), a well-documented variety of elephant, is also called "pygmy elephant." This elephant, inhabiting tropical rainforest in north Borneo (east Sabah and extreme north Kalimantan), was long thought to be identical to the Asian elephant and descended from a captive population. In 2003, DNA comparison revealed them to be probably a new subspecies.[2][3][4]

The term pygmy elephant should not be confused with "dwarf elephant", which is used for a number of extinct species of elephants that evolved their size due to island dwarfing.

Extensive Background[edit]

Pygmy elephants inhabited the islands from the Mediterranean region during the Pleistocene period but became extinct in the course of the Holocene. Despite striking distinctive anatomical characteristics related to insularity, some similarities with the lineage of extant Asian elephants have suggested that pygmy elephants could be most probably seen as members of the genus Elephas. Poulakakis et al. (2006) have recently challenged this view by recovering a short mtDNA sequence from an 800 000 year old fossil of the Cretan pygmy elephant (Elephas creticus).[5]
