Terrestrial locomotion has evolved as animals adapted from aquatic to terrestrial places. Movement on land makes different problems than that on water, with less friction instead being the effects of gravity.
There are three basic forms of movement found among land animals:
- Legged - Moving by using legs
- Limbless locomotion - moving without legs, mostly using the body
- Rolling - rotating the bod
Legged locomotion[change | change source]
Limbless locomotion[change | change source]
There are a number of land and amphibious limbless vertebrates and invertebrates. These animals, due to lack of legs, use their bodies to move. These movements are sometimes called to as "slithering" or "crawling".
