White-faced Saki monkey

Characterized by long, thick, fluffy hair on their heads, which makes them look larger and rounder than they actually are. The slightly flat face is covered with short hairs, just like the face of an old monk. It exhibits sexual dimorphism, with males being larger and having different colors between males and females. The fur colors of males and females are clearly different. Males are all black, with only white faces; females have shorter fur, which is mottled brown, with two pale vertical lines from the eyes to the nose, and may also have orange-brown fur around the chest and extending all the way to the abdomen.
It has a long, thick tail, which is usually 1:1 with the body length. It can be used to maintain balance when jumping from one tree to another, not for grabbing objects or branches. The large tail is about 34-45 cm long, so it is also called "fox-tailed monkey".
The diet of white-faced saki monkeys consists of seeds, fruit pulp, young leaves, insects and flow

Distributed in Brazil, French Guiana, Guyana, Suriname, Venezuela
The range of activities is limited to the evergreen rainforests of the Amazon River Basin. It likes to live in tropical highland and lowland rainforests. The altitude is 1-1000 meters. It is arboreal and lives in trees almost all its life.

The shiny tail of the white-faced Saki monkey is about 34 to 45 cm long, so it is also called the "fox-tailed monkey". There are two subspecies.

Male and female white-faced saki monkeys live in pairs for life, leading a traditional monogamous small group life, and only one baby is born each time.

As a herbivore, the white-faced saki monkey must face various toxins that other animals cannot handle. To protect against plant toxins, the white-faced saki has its own secret weapon - an extra-long intestine. These white-faced sakis are not much bigger than a house cat, but their intestines are as long as those of a gorilla. Leaves and seeds that would be poisonous to other animals are no threat to the white-faced saki.

The thick, long fur of the white-faced saki seems to be out of place in the hot tropical climate. They love honey very much, so they need this armor to deal with the owner of the honeycomb.

When a ground predator, such as a red-tailed boa constrictor, is near the white-faced saki, the white-faced saki will first sound the alarm, then gather together and besiege the predator in the hope of driving it away. Other natural enemies on land include sikas, jaguars, anacondas and margays. The biggest threat to the white-faced saki is birds of prey. Due to their small size, they are easily preyed on by harpy eagles. One study reported that when attacked by raptors such as eagles or vultures, white-faced saki monkeys will sound the alarm, and the group members will respond, and then they will completely freeze to protect themselves. They will then move as low as possible to the lowest part of the canopy, trying to hide themselves in the shade to achieve as much concealment as possible.

White-faced saki monkeys are a very unique creature that attracts high interest from visitors in zoos and is exploited for their own charm. These monkeys are captured as pets and traded in the market, which is very threatening to white-faced saki monkeys. They are also hunted by local indigenous people as a food source. These factors threaten the survival and population of the species because their slow reproduction rate cannot replace the number of people killed and hunted.
