It is a small nocturnal marsupial which lives in small groups or colonies. It has long hind feet and front feet with curved claws which it uses for digging food. Its body has large amounts of fur which helps with insulation, and its fur ranges between brown and grey; the color fading on its belly. This potoroo has a long, thin snout curving downward that it uses to smell its surroundings; this trait is common in all potoroo species. Its eyes appear to bulge out of its face and look as though they are on an angle and its ears are almost invisible, buried under thick fur. Male and female body types are very similar and are both within the same size range. Adult females range in weight from 708–1205 g (including pouch young where present), whereas adult males range in weight from 845–1200 g.〔"Biodiversity." Potorous Gilbertii — Gilbert's Potoroo. Australian Government, 16 July 2013. Web. 22 October 2013.〕 The current estimated population is a sparse seventy individuals. It was thought to be extinct until its rediscovery in 1994.〔Ernie Stead-Richardson, Don Bradshaw, Tony Friend, Terry Fletcher Monitoring reproduction in the critically endangered marsupial, Gilbert’s potoroo (Potorous gilbertii): Preliminary analysis of faecal oestradiol-17β, cortisol and progestagens General and Comparative Endocrinology, Volume 165, Issue 1, 1 January 2010, Pages 155–162〕 The only population is found in Two Peoples Bay Nature Reserve in Western Australia. == Discovery == Gilbert's potoroo was first discovered in 1840 and named in 1841 after the English naturalist and explorer John Gilbert.〔Krajewski, Carey. "Bettongs, Potoroos and the Musky Rat-kangaroo. Australian Natural History Series." Quarterly Review of Biology 83.4 (Dec. 2008): 419-419. 14 April 2009〕 Gilbert had collected several specimens at King George Sound in Australia, this potoroo being one of them. Gilbert's potoroo was not seen again for many years, even after a thorough search in the 1970s. The species was considered extinct for 20 years before it was rediscovered in 1994 in Two Peoples Bay Nature Reserve.〔"A Gap in Nature: Discovering the World's Extinct Animals." Australian Artist 18.6 (Dec. 2001): 2. April 2009〕〔Roger Underwood, (Doomed Planet: On the origin of the specious ), ''Quadrant'', 31 August 2012〕 Liz Sinclair had been doing research on wallabies and caught the potoroo in one of her traps.〔"Potoroo's return." New Scientist 144.1956 (17 Dec. 1994): 12. 14 April 2009〕 She then compared her captured specimen with the skeletons of past potoroos and proved it was indeed a Gilbert's potoroo. 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「Gilbert's potoroo」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
