The gelada is a unique species of primate found only in the highlands of Ethiopia. It is known for its distinctive long hair and a red patch of skin on its chest, which is more prominent in males. Geladas primarily feed on grass and are often seen grazing in large groups, making them one of the few primates that are primarily herbivorous. Geladas are social animals, living in troops that can consist of up to 100 individuals. They communicate using a variety of vocalizations and body language. Unlike many other primates, geladas do not have a strong hierarchical structure, allowing for more fluid social interactions within their groups.
