Cooperative breeding, where one individual cares for the offspring of another, occurs in several species, including wedge-capped capuchin monkeys.

The wedge-capped capuchin, weeper capuchin, or Ka'Apor capuchin (Cebus olivaceus) is a capuchin monkey from South America.

Researchers studying a group of wedge-capped capuchin monkeys that live in tropical forests of central Venezuela have discovered that the monkeys protect themselves against the annual merciless onslaught of mosquitoes exactly as humans do: by rubbing themselves with mosquito repellent.

Formerly considered a subspecies of the weeper capuchin (Cebus olivaceus), it was recently elevated to species status.

This group also includes the white-fronted capuchin, the weeper capuchin and the Kaapori capuchin.

The weeper capuchin is found over much of Venezuela and over The Guianas, as well as part of northern Brazil.
