Ethiopia is one of the few countries in the world, which possess unique and characteristic fauna with a high level of endemicity (World Conservation Monitoring Center (WCMC), 1991).

This large altitudinal and latitudinal range makes Ethiopia an ecologically diverse country and home to several unique habitats.

Ethiopia’s distinctive mammal fauna includes several genera found nowhere else including a primate, the Gelada, as well as the Gray-tailed Narrow-headed Rat, Nikolaus’s Giant Climbing Mouse, Yalden’s Rat, and the Ethiopian Water Mouse.
