Olive colobus  (Procolobus verus)

Description

The olive colobus has the distinction of being the smallest colobus monkey (2), a group of primates that primarily consume leaves and possess an unusual stomach that enables them to digest this plant matter efficiently (4). The olive colobus has greenish-olive fur graduating to brown on the back, and dull grey undersides. The small, rounded head has a short, grey crest running down the crown with a swirl of light grey hair on each side of the forehead. A dull white ruff frames the hairless dark face (2)
