Astounding Facts About Primates that Never Cease to Amaze

6. Geladas are the most terrestrial primates.
Most primates live in jungles, where they can nimbly climb up trees and, for many, swing through the branches. That is not the case with Gelada monkeys, who only live in a mountainous area of Ethiopia. The region is primarily rocks and has very little plant life. These monkeys have developed unique adaptations, such as short and stubby hands, perfect for traversing their rocky terrain. Their rear ends also have fatty pads to sit comfortably on the rock rather than the soft jungle floor. Geladas graze for grasses and are the last surviving grazing primates, which used to be much more predominant, particularly in Africa.

Geladas form the largest troops of possibly any other primates, with the most populous numbering well over 1000. They are organized much like human society, with the basic building block of the family. Families of geladas generally consist of one or two males, up to 10 females, and their offspring. These families converge in multiple social layers to form the famously large troops. Unlike other species, gelada troops can grow to such a large number because they feet on abundant grasses and do not have to compete in a scarce environment. Sadly, their population has declined significantly in recent years due to human activity such as agricultural development. It is devastating the grasslands on which they rely.
