The Chausingha (Tetracerus quadricornis) or four-horned antelope is the only animal in the world that typically has four horns - two pairs. The front pair is smaller than the rear pair. Bharal, Elk, and Blackbuck typically have two horns. The Chausingha is native to India and Nepal, and both males and females may have horns, though they're more prominent in males.
