The Vervet Monkey has three alarm calls, depending on the different types of threats to the community. There are distinct calls to warn of invading leopards, snakes, and eagles.

In dominance displays vervet monkeys run the gamut from shaking branches and jumping around to making a hard 'kek-kek-kek' sound to mark their territories.
The pigmentation of the male Vervet Monkey's scrotum is a vivid blue that pales when the animal falls in social rank. The hydration of the scrotal skin controls its color.
