The Preuss’s monkey[1] (Allochrocebus preussi), also called the Preuss’s guenon, is a diurnal primate that inhabits terrestrial montane forests (up to 2, 500 meters) in eastern Nigeria, western Cameroon, and Bioko in Equatorial Guinea.
- It was previously classified as a subspecies of L’Hoest’s monkey (Allochrocebus lhoesti). Preuss’s monkeys are large primates with short, thick black fur in various colors.
- A fluffy white section extends from the throat to the ears like a giant beard, and the limbs and belly are black.
- Their head, back, and tails are all splashed with white, making them look like someone was standing over them as they ate a particularly dusty funnel cake.
- Preuss’s monkeys are sexually dimorphic in size. Both sexes are mostly the same color, although males have a light blue scrotum.
- Females are also smaller and lighter than males.
