The nail-tail wallabies (genus ''Onychogalea'') are three species of macropod found in Australia. They are distinguished by a horny spur at the end of their tail. While the northern nail-tail wallaby is still common in the northern part of Australia,〔International Union for Conservation of Nature and Natural Resources ("Onychogalea unguifera" ), The IUCN Red List of Threatened Species, 2008〕 the crescent nail-tail is now extinct,〔International Union for Conservation of Nature and Natural Resources ("Onychogalea lunata" ), The IUCN Red List of Threatened Species, 2008〕 and the bridled nail-tail is considered rare and endangered, with probably fewer than 1100 mature individuals in the wild.〔International Union for Conservation of Nature and Natural Resources ("Onychogalea fraenata" ), The IUCN Red List of Threatened Species, 2008〕 Nail-tail wallabies are smaller than many other wallabies. ==Species== There are three species: * Bridled nail-tail wallaby, ''Onychogalea fraenata'' *† Crescent nail-tail wallaby, ''Onychogalea lunata'' * Northern nail-tail wallaby, ''Onychogalea unguifera'' 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Nail-tail wallaby」の詳細全文を読む スポンサード リンク
