The nail-tail wallabies, of genus Onychogalea, are three species of macropods, all found in Australia. Related to kangaroos and wallabies, they are smaller species distinguished by a horny spur at the end of their tail. The northern nail-tail wallaby is still common in the northern part of Australia, the crescent nail-tail is now extinct, and the bridled nail-tail is considered rare and endangered, with probably fewer than 1100 mature individuals in the wild. Nail-tail wallabies are smaller than many other wallabies.
