Beddome, 1889) * ''Aaadonta irregularis'' Semper, 1874 * ''Aaadonta kinlochi'' Solem, 1976 * ''Aaadonta pelewana'' Solem, 1976 The genus was given its unusual name by the biologist Alan Solem, who wanted it to appear first in any alphabetical list of endodontid genera.〔"''Aaadonta'' and ''Zyzzyxdonta'' (terrestrial snails) both named by the late Alan Solem with the idea of being the first and the last entries in any list of endodontoid snails." - Shimek, R.L. in (''The Mollis Clans - A Celebration of Molluscan Diversity'' )〕〔(Zoologische Mededelingen ). Dpc.uba.uva.nl. Retrieved on 2010-09-27.〕 For animal genera, the first alphabetically listed name is ''Aaaaba'', which is a genus of beetles from Australia. The current conservation status, according to the IUCN Red List, varies depending on species, though they all fall into the larger category of being threatened. One cause of a low population stated by Solem could be that ant colonies that come into the area can prey on eggs of the various species, thus wiping out a large number of snails, potentially without harming the adult snails. Some species, like the fuscozonata, have not been found recently and leads researchers to believe that they may already be extinct. 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「Aaadonta」の詳細全文を読む スポンサード リンク
