Mammals are divided into two subclasses based on reproductive techniques: egg laying mammals (the monotremes), and live birth mammals. The second subclass is divided into two infraclasses: pouched mammals (the marsupials) and placental mammals. Australia is home to two of the five extant species of monotremes and the majority of the world's marsupials (the remainder are from Papua New Guinea, eastern Indonesia and the Americas). The taxonomy is somewhat fluid; this list generally follows Menkhorst and Knight〔Menkhorst, P. and Knight, F. (2001) ''A Field Guide to the Mammals of Australia'', Oxford University Press, Melbourne ISBN 0-19-550870-X〕 and Van Dyck and Strahan,〔Van Dyke, S. and Strahan, R. (eds.) (2008) ''The Mammals of Australia'', Third Edition, New Holland / Queensland Museum, Brisbane ISBN 978-1-877069-25-3〕 with some input from the global list, which is derived from Gardner and Groves. This is a sub-list of the list of mammals of Australia. Conservation status listed follows the IUCN Red List of Threatened Species (v. 2013.2; data current at 〔(【引用サイトリンク】 The IUCN Red List of Threatened Species )〕): - extinct - extinct in the wild - critically endangered - endangered - vulnerable - near threatened - least concern - data deficient - not evaluated ==Monotremata (monotremes)== 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「List of monotremes and marsupials of Australia」の詳細全文を読む スポンサード リンク
