==Description==

'''Walking''' (also known as ''ambulation'') is one of the main gaits of locomotion among legged [[animals]], and is typically slower than running and other gaits. Walking is defined by an 'inverted [[pendulum]]' gait in which the [[body]] vaults over the stiff limb or limbs with each [[step]]. This applies regardless of the number of limbs - even arthropods, with six, eight or more limbs, walk.
