Like the giraffe and unlike other ungulates, the okapi simultaneously steps with the front and hind leg on the same side of the body.
The walking gait of the okapi closely resembles that of a giraffe. Both, giraffe and okapi, simultaneously step with the front and hind leg on the same side of the body rather than moving alternate legs on either side like other ungulates. Okapi also have a pacing gait and can gallop.
