Northern white-cheeked gibbon

(Nomascus leucogenys)


Northern white-cheeked gibbons are sexually dimorphic,with males and females having different colourations and the former also being slightly larger.Males have black hair over their entire bodies,except for distinct white patches on their cheeks,as well as a prominent tuft of hair on the crown of head,and a gular sac.Females are reddish-tan in colour,lack a cranial tuft,and have a crest of black or dark brown fur running from the crown to the nape of the neck.They are reported to have an average weight of 7.5 kg (17 lb),although this is based on only a small number of wild individuals,and those in captivity appear to be larger.
