The toque macaque is a stocky monkey, characterised by an unusual whorl of hair on top of the head that grows from the central crown (2). The name toque macaque refers to this ‘cap' of hair; toques are brimless hats. The coat is reddish or yellowish brown in colour and the underparts are paler (2). All individuals have cheek pouches, used to carry food whilst foraging (5), short, stout limbs and long tails (6). The skin on the face is naked; the ears, border of the eyelids and lower lip are pigmented black, with the remainder of the face pinkish in males, reddish in females (3). Males tend to be larger in size than females (2).
