A type of primate locomotion
which involves both forelimbs and the hindlimbs, although not to an equal extent. Some quadruped
s are hindlimb dominated, while the forelimb and the hindlimb are equally important to others.
There are several different kinds of quadrupedalism, as follows:
- Branch running and walking, in which the animal walks along a branch grasping it with both their hands and feet.
- Ground running and walking, in which the animal walks on the ground using both hands and feet, the plans of the hand flat on the ground.
- Knuckle walking, a form of semi-quadrupedalism, found in chimpanzees and gorillas, in which the upper parts of the body are supported by the knuckles rather than the palms.
- New World semibrachiation is a pattern involving using a prehensile tail in addition to the hands to suspend their bodies.
- Old World semibrachiation is using the arms extending to grasp a branch, and commonly leaping.
