What physical feature gives the capuchin monkeys their name resemblance?
Answer
The patch of black fur on the crown of the head strongly resembles a black cap.
The designation 'capuchin' is directly derived from the monkey's distinctive physical appearance, specifically referencing a feature that mimics historical religious attire. The patch of black fur situated on the crown of the head is a highly recognizable marking, commonly referred to as a black cap. This dark cranial marking bears a strong visual similarity to the hooded cowl traditionally worn by the Capuchin friars belonging to the Order of Friars Minor. This specific analogy in appearance is the historical basis for naming the entire group of monkeys after this religious order, establishing a permanent link between their coloration and their common name.
