Monkey does selfie: A black crested macaque (Macaca nigra) takes a photo of herself
The macaques are a genus (Macaca) of Old World monkeys of the subfamily Cercopithecinae. The 22 species of macaques live in sub-Saharan Africa, and more widely in Asia. One species is the well-known Gibraltar 'ape'. Macaques are of some interest to human researchers for their social structures, and their usefulness in animal testing, particularly regarding eyesight.
