"Vertical clinging and leaping" is a type of arboreal locomotion seen most commonly among the strepsirrhine primates, and particularly the members of the family Indriidae. At rest, the animal clings to a vertical support, such as the side of a tree or bamboo stalk. To move from one plant to another, it pushes off from one vertical support with its hindlimbs, landing on another vertical support.[1]
