Grivet

Description

These are midsize primates whose coats have bright colours: the dorsal region is reddish, the ventral area white and they have bluish colours on the face, with a yellowish mask. The tail is long and they use it to keep balance as they jump from branch to branch. The males are slightly larger than the females. 

Behaviour

They are diurnal, sociable and live in groups of 20-35 individuals that move through the treetops, led by a dominant male. The females do not show physical signs during mating season, such as swelling of the genital area; they only release pheromones that the male detects. When they perceive danger, they remain completely frozen until the threat has passed. 

Interesting facts

They are very noisy, which means their predators can detect them easily. The main threats they are facing are habitat destruction and hunting for their meat, although their great adaptive capacity has allowed them to travel to new areas where it is harder to find them.
