The Ryland’s Bald-Faced Saki[1] (Pithecia rylandsi) is a controversial species of saki monkey, a New World Monkey species. It is one of the largest sakis.
- This species is easily distinguished from all other sakis by its large size, black, bare face, and highly whitish-gray hair, often making older males appear almost entirely white.
- Young males are black with medium gray.
- Adult females are nearly as intensely white as males, and their forehead hair may form white “fringes“.
