grivet

thumb|Female in Ethiopia

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. As here defined, the grivet is restricted to Ethiopia, Sudan, Djibouti, and Eritrea. In the southern part of its range, it comes into contact with the closely related vervet monkey (C. pygerythrus) and Bale Mountains vervet (C. djamdjamensis). Hybridization between them is possible, and may present a threat to the vulnerable Bale Mountains vervet. Unlike that species, the grivet is common and rated as least concern by the IUCN.
