Detailed explanation-1: -Orangutans, spider monkeys, and chimpanzees can brachiate, but gibbons do it most often. Long arms and fingers, and mobile shoulder joints, help them move easily from branch to branch.
Detailed explanation-2: -Gibbons in particular use brachiation for as much as 80% of their locomotor activities. Some New World monkeys, such as spider monkeys and muriquis, were initially classified as semibrachiators and move through the trees with a combination of leaping and brachiation.
Detailed explanation-3: -Brachiation-aiding traits Some of the traits that allow gibbons, siamangs, and other primates to brachiate include the following: short fingernails instead of claws, inward-closing, hook-like fingers, opposable thumbs, long forelimbs, and freely rotating shoulder joints.
Detailed explanation-4: -Brachiation is a rare ability for primates. None of the prosimians do it. Among the monkeys, only a few New World species have the capability, and they don’t use it as frequently as the gibbons.
