The Calamian deer is a fairly small and heavy-bodied deer, with relatively long legs. Its coarse hair is tawny-brown with darker underparts, and the legs are darker than the rest of the body. The face has subtle white markings around the muzzle, inside and at the base of the ears, and on the throat, and the underside of the short, bushy tail is also white. Undoubtedly, the most distinctive feature of the Calamian deer is the three-pronged antlers of the male: bony, hornlike appendages that are typically shed and regrown each year.
