  • This species is a relatively small monkey, and there are no differences in appearance between males and females.

  • This monkey has a slightly astonished look due to its large eyes, but unlike many nocturnal species, the eyes do not shine in torch light. This is because they do not have a ‘tapetum lucidum’ – the reflective layer behind the retina of night-time animals that enhances the amount of light they can receive. The lack of this layer betrays the grey-legged night monkey’s relatively recent evolutionary split from diurnal monkeys.

Primary forest and very old secondary forest of Colombia and Venezuela.
