The grivet (Chlorocebus aethiops) is an Old World monkey with long white tufts of hair along the sides of its face.

Some authorities consider this and all of the members of the genus Chlorocebus to be a single species, Cercopithecus aethiops.

[6] The body mass ranges from 3.4 to 8.0 kg (7.5 to 17.6 lb), with females at the smaller end of the scale.

[2] In Tigrinya language: ወዓግ (wi’ag)[7] The grivet is most active in the morning and early evening.

[8] They travel in packs, and usually move on all fours or quadrupedally, except when using both hands for carrying, when they manage to walk and run quite comfortably on two legs.

Giving birth to one baby at a time is common, and gestation usually lasts 2-3 months.

When the baby is born, the mother cleans the infant and bites off the umbilical cord.

Grivets were imported from the Land of Punt, as attested in paintings and in the Tale of the Shipwrecked Sailor.

[10] Grivets are depicted on Egyptian tombs as house pets and on leashes.

Early Dynastic statuettes of grivets have been found in sanctuaries, where they may have been votive offerings to the baboon god.

[10] Since the 1960s, the grivet has been harvested on an industrial scale by humans for their kidneys, which are used in poliovirus and adenovirus vaccine production.
