What pattern on the Cebus head inspired the "Capuchin" name?
Answer
A patch of black fur resembling a cowl or beanie.
The common name "Capuchin" derives directly from a distinctive physical feature observed on the top of their round heads. This feature is a patch of black fur that closely resembles the hooded robes worn by Capuchin friars. This characteristic coloration pattern, set against the lighter fur of the neck and shoulders, is a key element of their appearance.
