This species presents sexual dimorphism, being the females smaller and less corpulent than the males; they never have horns. Some male individuals have horns that are renewed every year and, in subspecies, a dense mane of dark hair on the neck and shoulders.
The color of the hair is normally brown throughout the body except on the belly and buttocks, whitish, and can vary in the intensity of its tonality according to the individuals. The young of a few months have a reddish coloration, with white spots and stripes that help them hide from predators.
