Terrestrial locomotion
Terrestrial locomotion has evolved as animals adapted from aquatic to terrestrial environments. Locomotion on land raises different problems than that in water, with reduced friction being replaced by the effects of gravity.There are three basic forms of locomotion found among terrestrial animalsLegged - Moving by using appendagesLimbless locomotion - moving without legs, primarily using the body itself as a propulsive structure.Rolling - rotating the body over the substrate
