''Cyclura'' is a genus of lizards from the family Iguanidae. Members of this genus are known as "cyclurids" or more commonly as rock iguanas and only occur on islands in the West Indies.〔 〕 Rock iguanas have a high degree of endemism, with a single species or subspecies restricted to individual islands.〔 〕〔 〕 ==Taxonomy== The generic name (''Cyclura'') is derived from the Ancient Greek ''cyclos'' (κύκλος) meaning "circular" and ''ourá'' (οὐρά) meaning "tail", after the thick-ringed tail characteristic of all ''Cyclura''. Currently there are nine described species and eight subspecies identified in this genus.〔〔Frost, D.E. and R.E.
