[[Elephants]] can move both forwards and backwards, but cannot [[trot]], [[jumping|jump]], or [[Horse gait|gallop]]. They use only two gaits when moving on land, the walk and a faster gait similar to running.<ref>{{cite journal | last1 = Shoshani | first1 = J. | last2 = Walter | first2 = R.

With no "aerial phase", the fast gait does not meet all the criteria of running, although the elephant uses its legs much like other running animals, with the hips and shoulders falling and then rising while the feet are on the ground.<ref name="kinetics">{{cite journal |author = Hutchinson, J.
