There's a whole gelada fur in this photo. Found in the Ethiopian Highlands, geladas are the only grass-grazing monkey in the world. Their thick fur helps them stay warm in the high elevations while a reinforced tush (AKA ischial callosities) provides cushion for all day grazing. #GeladaFun #itscalledfashion #lookitup #WinterEdition #sandiegozoo 📷: Mike Wilson
