Almost all mammals with prehensile tails live in the neotropics because the forest is different there.

FYI: We try to leave jargon out of our videos, but if you want to learn more about this topic, here are some handy keywords to get your googling started:
Prehensile Tail: An animal tail that can grasp or hold objects. A wide range of animals have prehensile tails, including mammals (like opossums and kinkajous), reptiles (like chameleons), amphibians (like salamanders), and fish (seahorses).
Old World Monkeys (Cercopithecidae): A family of primates native to Africa and Asia that includes baboons, guenons and macaques – all of which have non-prehensile tails.
New World Monkeys (Platyrrhini): A family of primates native to Central and South America that includes spider monkeys, howlers, and capuchins – all of which have prehensile tails.
Prehensile tails evolved twice in new world monkeys: In atelines (spider monkey and howlers) the prehensile tail tip is like a finger and incredibly dextrous. In cebines (capuchin monkeys) the tip is furry and not quite as dextrous.
