The San Salvador rock iguana (''Cyclura rileyi''), also known as the Bahamian rock iguana, is a critically endangered species of lizard native to three island groups in the Bahamas. The species is in decline due to habitat encroachment by human development and predation by feral dogs and cats. There are three subspecies: the Acklins ground iguana (''Cyclura rileyi nuchalis''), the White Cay iguana (''Cyclura rileyi cristata'') in addition to the nominal subspecies (''Cyclura rileyi rileyi''). ==Taxonomy== The San Salvador rock iguana is an endangered species of lizard of the genus ''Cyclura'' from the family Iguanidae. First identified by Leonhard Hess Stejneger in 1902, they are known commonly in the Bahamas as iguanas. Its generic name ''Cyclura'', is derived from the Greek words ''cyclos'' meaning "circular" and ''urus'' meaning "tail", after the thick ringed tail characteristic of all ''Cyclura'' iguanas.〔 〕 Its specific name, ''rileyi'', is a Latinized form of the name of American biologist, Joseph Harvey Riley. As of 1975 two additional subspecific forms have been identified along with the nominal subspecies: the Acklins ground iguana (''C. r. nuchalis'') and the White Cay iguana (''C. r. cristata'').〔 Together they are one of the most threatened species of all the West Indian rock iguanas and are described as critically endangered according to the current IUCN Red List.〔 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「Cyclura rileyi」の詳細全文を読む スポンサード リンク
