 One unique morphological characteristic is the distinct primitive cuspidate pattern of their cheekteeth, which have hypsodont molars, teeth crowned earlier in life and the outer fold of the upper molars tend to be more isolated as enamel islands.The "Nectomys squamipe" tends to have relatively longer, less hairy ears and a glossy, long pelage.This pelage is made up of wool hairs and guard hairs and is darker dorsally and tends to be lighter grey on its sides and ventrally.
