 It has become commonplace to refer to the Borneo elephant as a ‘pygmy’ subspecies, although adult elephants of Sabah of both genders are similar in height to their counterparts in Peninsular Malaysia.Five measurements of the skull of a fully adult female elephant from Gomantong Forest Reserve were slightly smaller (72–90%) than comparable dimensions averaged for two Sumatran skulls.Few available measurements show that they are of similar size to other populations of the Sunda subregion.
