Northern Bahamian rock iguana
The northern Bahamian rock iguana (''Cyclura cychlura'') is a species of lizard of the genus ''Cyclura'' that is found on the Andros and Exuma islands in the Bahamas. Its status on the IUCN Red List is Vulnerable, with a wild population of less than 5,000 animals.
==Taxonomy==
The northern Bahamian rock iguana's generic name ''Cyclura'' and specific name ''Cychlura'' are derived from the Ancient Greek ''cyclos'' (κύκλος) meaning "circular" and ''ourá'' (οὐρά) meaning "tail", after the thick-ringed tail characteristic of all cyclurids. Its closest relatives are ''Cyclura nubila'' on Cuba, and ''Cyclura lewisi'' on Grand Cayman. All three apparently diverged from a common ancestor some 3 million years ago.
There are three subspecies of the northern Bahamian rock iguana: the Andros Island iguana (''Cyclura cychlura cychlura''), Allen's Cay iguana (''Cyclura cychlura inornata''), and the Exuma Island iguana (''Cyclura cychlura figginsi'').〔 Biologist Catherine Malone describes ''C. c. cychlura'' as being phylogenetically different from ''C. c. figginisi'' and ''C. c. inornata'' but does not recognize them as separate species; the three are listed as subspecies until further study has been completed.〔
