Question

Dancing lemurs have an upright posture with legs that are much longer than their arms. They are great aerial acrobats as they swiftly leap from tree to tree. On the ground, they are not able to walk on their four legs instead they perform a sideways bounce on their two legs while holding their arms out for balance, mimicking their leaps from tree to tree. This is an example of ___________.

Answer 1

Suspensory locomotion (suspensory behavior)

Explanation:

Suspensory locomotion, also known as suspensory behavior, is a concept that refers to several specialized forms of locomotion observed in some primates, and in other arboreal mammals, which involves hanging the body among tree branches, thereby distributing the body weight to different branches of the trees. Suspensory locomotion includes three specialized types of locomotion: brachiation, climbing, and bridging. It is an adaptive strategy that enables suspensory animals to travel faster and avoid predators during arboreal movement and foraging. Some examples of suspensory primates include, among others, lemur, spider monkey, Bornean orangutan, etc.
