A potoroo is a kangaroo-like marsupial about the size of a rabbit. It is a macropod. All three extant species are threatened, especially the long-footed potoroo (Endangered) and Gilbert's potoroo (Critically Endangered). The main threats are predation by introduced species (especially foxes) and habitat loss. Potoroos were formerly very common in Australia, and early settlers reported them as being significant pests to their crops. Gilbert's potoroo is Australia's most endangered animal. The species was discovered in 1840 by a naturalist called John Gilbert. It was then thought to have become extinct until being rediscovered in 1994 at the Two Peoples Bay Nature Reserve (near Albany) in Western Australia. Conservation efforts have grown an initial wild population of 30-40 to over 100 〔(【引用サイトリンク】 date=December 2014 )〕 ==Classification== A potoroo is any member of the genus ''Potorous''. * Suborder Macropodiformes * * Family Potoroidae * * * Subfamily Potoroinae * * * * Genus ''Potorous'' * * * * * Gilbert's potoroo, ''P. gilbertii'' * * * * * Long-footed potoroo, ''P. longipes'' * * * * * †Broad-faced potoroo, ''P. platyops'' * * * * * Long-nosed potoroo, ''P. tridactylus'' 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「potoroo」の詳細全文を読む スポンサード リンク
