Detailed explanation-1: -Gracile capuchin monkeys (genus Cebus) live in the tropical rainforests of South America, inhabiting the forests of Brazil, Bolivia, Colombia, Ecuador, Peru, and Venezuela. They are arboreal animals, so they live most of their lives high in the trees. Gracile capuchin monkeys are small, with a weight of 3–9 pounds.

Detailed explanation-2: -Unlike some Old World monkeys, all NWMs are arboreal and, with the exception of the owl monkeys (Aoutus), diurnal. They are small to medium sized primates (ranging from 0.1 kg to 15 kg) and are distinguished from the catarrhines by several features.

Detailed explanation-3: -Except for a few Old World forms, monkeys are predominantly arboreal, leaping from limb to limb in their travels among the trees.

Detailed explanation-4: -The New World monkeys are all arboreal, whereas Old World monkeys include arboreal and ground-dwelling species.
