A strange-looking monkey caught the attention of people recently. While visiting Nanjing Hongshan Forest Zoo, a tourist saw this monkey and took a photo of it and posted it online. Many people were shocked by its look, saying that it looks like the “No Face” in the animated film Spirited Away. The staff at the zoo later explained that this monkey is a white-faced saki monkey called “Dudu”.
The white-faced saki (Pithecia pithecia ) is a species of the New World saki monkey. It can be found in Brazil, French Guiana, Guyana, Suriname and Venezuela. This species feeds mostly on fruits, nuts, seeds, and insects. White-faced sakis typically live around 14 years in their natural habitat and have been recorded to live up to 36 years in captivity. Sakis are active in the day and sleep highly elevated (15-20m) in trees with many leaves to shelter them from weather and flying predators(捕食性动物).
White-faced sakis gather into very small units of only 2 - 4 individuals. Group members take daily trips of 1 - 2 kilometers. They are most active in the early morning and early afternoon. As much as 9 hours of their active time are spent travelling. When moving, they use all of their four limbs(肢). These monkeys actively use vocalizations(发声) in the daily life. Meanwhile, loud calls act as a territorial display. When facing a threat, these animals give out growling noises, puff themselves up to look bigger than they are as well as shake branches of trees at full strength.
White-faced sakis are primarily threatened by loss of their natural habitat as a result of deforestation(滥伐森林). These monkeys attract hunters for their meat as well as their highly-valued tails. In addition, some individuals of this species are caught and sold as pets. According to IUCN, the White-faced saki is relatively common and widespread throughout its range but no overall population estimate is available.
