They've Got Long Arms

The length of an orangutan's arm is 1.5 times that of their leg. An adult male orangutan's arms may be as long as 213 cm (7 ft.) when spread out to the sides. They can swing from tree to tree because of their powerful arm muscles, which also help their shoulders sustain their whole weight. An orangutan is around seven times powerful than a human, yet not as strong as a gorilla.

Orangutans have arms that are longer than their legs and shoulders that are wider than their hips because they travel through the jungle more with their arms and shoulders than with their legs and hips.

Orangutans' legs are smaller than their arms since they are not utilized for swinging and do not bear the weight of the animal. Orangutans have extremely movable hips. Their joints can fully rotate, which enables them to move their legs at practically any angle. Orangutans can jump, twist, grab, and balance as they swing from branch to branch thanks to their flexible knee and ankle joints.
