Question

Name and describe 5 types of locomotion modes for Non-Human Primates?

Answer 1

Brachiating:

Brachiation is a specialized form of arboreal locomotion in which movement is accompained by swinging from one hold to another hold by using arms. The process is highly developed in the  siamang and gibbon.

Quadrapedalism:

Quadrupedalism is divided into arboreal and terrestrial versions.

Quadrupedal primates have fore- and hind limbs of relatively equal length and they tend to lower their centers of gravity toward the branch by bending their elbows and knees.

Arboreal quadrupedal primates use their hands and feet toward the support.

Terrestrial quadrupedal primates have same fore and hind limb lengths, but these primates have low joint mobility

Leaping :

it means the forceful upward parabolic movement.

Eg. Strepsirhine primates and tarsiers

Habitual Bipedalism:

Bipedalism means to locomoting on two legs.

It is not uncommon to walking on teo legs, but only a less number of animals practice bipedalism as their locomotion.

Slow Quadramanous Climbing:

Moving up vertical substrates is called Quadramanous Climbing. It is well documented across all primates.

Knuckle Walking:

The forelimbs hold the fingers in a flexed position that allows the body weight to press downward to the ground by the knuckles.

E.g: Gorillas and chimpanzees.
