This large, heavily built deer has a dark slate-gray coat with a bright yellow rump patch in winter, but color is reddish in summer. The thighs, shoulders, and underparts are black or dark brown. This deer shows the characteristics of both a typical red deer and the wapiti. Male deer roar in a fashion similar to other European red deer, have five pronged antlers with cups, and may rival Rocky Mountain elk (Cervus canadensis canadensis) in size. Maral deer are similar to wapitis in having large bez (second) tines and a large rump-patch.
