English: The toque macaque (Macaca sinica) is a reddish-brown-coloured Old World monkey endemic to Sri Lanka, where it is known as the rilewa or rilawa (Sinhala: රිළවා),

Toque macaques are the smallest species of Macaca. They have a golden brown coat on their dorsal surface and white hair on their ventral surface. This white coat extends to the cheeks and around the ears. The have a small tuft of hair on the top of their head that resembles a hat.

They are fond of eating drooping yellow clusters of flowers of Cassia fistula. They eat any good thing making use of human detritus by going after plantains, pineapples, rice grains, papaws, and mangoes. Even there are plenty of foods present in natural habitation, toque macaques enjoy to take any food with little effort around human dwellings. They are occasionally seen around houses near a forest patch, where they invade all the fruiting plants in the day sessions and return to the forest cover in night. Because, these macaques have very little fear for humans and their companions-the dogs.Wild cats (leopards and fishing cats) and Indian rock python are the main predators of this species.
