Gelada vs Baboon for Kids
Geladas were once commonly called gelada baboons, but they are not true baboons in genus Papio. The Gelada, Theropithecus gelada, is the only living member of its genus. It grazes in the Ethiopian and Eritrean highlands and has a bright red chest patch. This page compares it with the Olive Baboon, Papio anubis, a long-muzzled omnivore found across a much wider part of Africa.
Gelada
- Type: Living
- Group: Grass-eating monkey and the only living species in genus Theropithecus (Theropithecus gelada)
- Known for: Short muzzle, pale eyelids, red chest patch, long male shoulder cape and highly specialized grass eating
- Diet: Herbivore and mainly a grazer; eats grass blades and seeds plus roots, flowers, stems and some fruit
- Special skill: Shuffles across the ground while seated, plucking grass quickly with very nimble fingers
Olive Baboon
- Type: Living
- Group: Large true baboon in genus Papio (Papio anubis)
- Known for: Olive-gray speckled coat, long dog-like muzzle, powerful male mane, cheek pouches and a bent-looking tail
- Diet: Omnivore; eats grass, roots, fruit, leaves, seeds and bark plus insects, eggs and small animals
- Special skill: Uses cheek pouches to gather food quickly and can switch among foods on the ground, in trees and underground
Quick Answer
A Gelada has a short face, pale eyelids and a bare red patch on its chest. It spends much of the day sitting and plucking grass in cool highland meadows. An Olive Baboon has a long dog-like muzzle, an olive-gray coat and cheek pouches for carrying food. It lives in many warmer habitats and eats both plants and small animals.
