This capuchin has a conspicuous dark cap of hair. It lives in forest groups and ranges farther to find food when fruit is scarce.
Its fur is longer, silkier, and less brightly colored than that of C. unicolor. The dark brown cap is distinct; males have a broad pale forehead, while the female's dark forehead band continues into the cap.
Groups average about 15 individuals, with an approximately even sex ratio. During fruit shortages, it travels farther to forage than the compared Sapajus species.
