Gelada

 

(Theropithecus gelada), a monkey of the family Cercopithecidae, order of Primates. In males body length is 70-74 cm; tail length, 46-50 cm; and weight, approximately 20 kg. Females are smaller: body length, 50-65 cm; weight, approximately 13 kg. Geladas resemble baboons. The male’s mantle of fur is brown, and the female has gray fur. There is an hourglass patch of bare red skin on the chest. Geladas are found in the mountains of Ethiopia above 2,000 m. They live in rocky areas in herds of up to 400 and feed on onions, grasses, and insects. They rarely climb trees.
