Elephas is one of two surviving genera in the family of elephants, Elephantidae, with one surviving species, the Asian elephant, Elephas maximus.[1]

Several extinct species have been identified as belonging to the genus, including Elephas recki, straight-tusked elephant E. antiquus and the dwarf elephants E. falconeri and E. cypriotes. The genus is very closely related to the genus Mammuthus.[2]

Taxonomy[edit]

The scientific name Elephas was proposed by Carl Linnaeus in 1758 who described the genus and an elephant from Ceylon.[3] The genus is assigned to the proboscidean family Elephantidae and is made up of one living and seven extinct species:[4]

The following Asian elephants were proposed as extinct subspecies, but are now considered synonymous with the Indian elephant:[1]

The following Elephas species are extinct:
