The mountain zebra subspecies, Hartmann’s zebra, like the Cape mountain zebra of South Africa, has solid stripes while Burchell’s zebra, seen in abundance on the grasslands of Etosha National Park, has additional faint stripes superimposed on the white and referred to as shadow stripes. On closer observation, it will be noticed that the Hartmann’s zebra stripes don’t join on its stomach and continue down to its hooves, whereas Burchell’s stripes extend onto its underparts and often fade towards its hooves. There are two more obvious differences. Hartmann’s zebra Equus zebra hartmannae has a grid-iron pattern across the top of its rump and a prominent dewlap on its throat. Equus burchellii lacks both of these features.
