Locomotion by swinging arm-over-arm.
To move around in trees by arm-swinging beneath branches.
Brachiation (to brachiate) means to move by swinging with the arms from one hold to another (like one maneuvers on an Overhead ladder); for example through a tree, using branches as holds. Many primates use this method to move through forest quickly. True brachiation is only seen in lesser apes (gibbons) and spider monkeys.
