Strangely, this rare monkey with a prominent white T on its face is known as the Owl-faced Monkey.
It is also known as Hamlyn's Guenon and is native to thick forest of the Congo, Central Africa.
Mature males are larger than females and both have a pale blue bottom; Mr T also has red and blue genitals.
Like some other guenon species, they live in single gender groups; the female group, led by senior females, includes one breeding
adult male at times and male youngsters.
