The hartebeest is a large, fawn-colored antelope that, at first glance, seems strangely less elegant than other antelopes. However, being one of the most recent and highly evolved ungulates, it is in fact, one of the fastest antelopes and most enduring runners. These qualities gave rise to its name, which means "tough ox." Its sedentary lifestyle seems to inhibit the mixing of populations and gene flow, and as a result, there are several subspecies of hartebeest. Hartebeest are mainly found in medium and tall grasslands, including savannas. They are more tolerant of high grass and woods than archetypical plains antelopes.
