A typical Goa stands about two feet tall at the shoulder and weighs around 50 pounds. Males have long, tapering, ringed horns, reaching lengths of up to 14 inches. Females have no horns; neither have distinct facial markings. They are gray in color, with a white underbelly. Mating season is in December, with young born the following May.
The Goa is considered endangered, due to over-hunting; fewer than 150 are thought to remain in the wild.
