Weeper Capuchin (Cebus olivaceus) lives in tropical rainforest across South America. It feeds on fruits and insects. Its conservation status is Least Concern.
Fascinating facts about the Weeper Capuchin
- The wedge-capped capuchin rubs millipedes onto its fur during the rainy season, using the arthropods as a makeshift mosquito repellent. This behaviour has been recorded in wild groups that inhabit tall, primary forests of northern Brazil, Guyana and Venezuela. By applying the millipedes the monkeys gain temporary protection from biting insects, an adaptive trick that complements their omnivorous diet of fruit and invertebrates.
- Male wedge-capped capuchins possess dramatically larger canines than females, with upper canines about 70 % larger and lower canines 40 % larger. On average males weigh roughly 30 % more than females, reflecting the same pattern of sexual dimorphism seen in other capuchins. The oversized teeth and greater body mass are thought to signal intense male competition for mates within the polygamous groups.
- Wedge-capped capuchins have been observed washing sandy fruit before consumption, a behaviour recorded on only four spontaneous occasions in both captive and wild populations. Researchers noted that the washing occurs as a direct response to problematic food conditions rather than through imitation, suggesting a rudimentary form of protoculture. This rare habit shows the species' ability to manipulate its environment to improve food safety.
- Alloparenting, where members of the group care for offspring that are not their own, occurs in wedge-capped capuchins. It is listed among the behaviours the species uses to assert and maintain dominance within the group.
- The wedge-capped capuchin has a diploid chromosome number of 52, while some other capuchin species have 54. Nine human chromosomes correspond to those of C.
