White-faced monk monkey: 33-35 cm long, weighs 0.7-2.5 kg, round and slightly flattened face, the face plate is covered with short fur, living like the face of an old monk. The large shiny tail is about 34-45 cm long, so it is also called "lemur".
Inhabiting the upper canopy area of the tropical rainforest, it lives almost all the time in the trees, daily, with small differences between male and female, monogamous family units, and groups of 5-9 animals living together.
It feeds on fruits, but also leaves and underripe seeds. It eats fruits as a staple food, but also eats some flowers, leaves and animal foods. During the day, he forages, eating seeds, leaves, flowers, fruits, insects, and occasionally eating small animals such as birds, mice, bats, and lizards.
The gestation period is about 163-176 days, and the interval and seasonality of each litter are unknown. It is found in Brazil, Guyana, Suriname and Venezuela.
The white-faced monk monkey's thick long hair looks like it doesn't fit in with the hot climate of the tropics, but it's made for the mouth, and the white-faced monk monkey loves honey so much that it needs this armor to deal with the owner of the honeycomb.
The white-faced monk monkey has its own secret weapon, an extra-long intestine. These white-faced monk-faced monkeys are not much bigger than domestic cats, but their intestines are as long as gorillas'. The leaves and seeds that poison other animals are not a threat to the white-faced monk monkeys.
