Cyclura Rock Iguanas Cyclura is a genus of lizards in the family Iguanidae. Member species of this genus are commonly known as "cycluras" or more commonly as rock iguanas and only occur on islands in the West Indies. Cyclura Rock iguanas have a high degree of endemism, with a single species or subspecies restricted to individual islands.
