Cercopithecus sabaeus; Print; The green monkey (Chlorocebus sabaeus); also known as the sabaeus monkey or the callithrix monkey; is an Old World monkey with golden-green fur and pale hands and feet. The tip of the tail is golden yellow as are the backs of the thighs and cheek whiskers. It does not have a distinguishing band of fur on the brow; like other Chlorocebus species; and males have a pale blue scrotum. Some authorities consider this and all of the members of the genus Chlorocebus to be a single widespread species; Chlorocebus aethiops.; 1700-1880
