Ctenosaura pectinata;Ctenosaura similis
Two species of Spiny-tailed iguanas or ctenosaurs, Ctenosaura pectinata (WIEGMANN, 1834) and C. similis (GRAY, 1831), have been introduced in Florida. Populations on Key Biscayne, Miami-Dade County, and Gasparilla Island, Charlotte and Lee counties, are reported to be C. pectinata. However, the status and distribution of C. similis are reported to be poorly known. After conducting herpetofaunal surveys since 1995 in areas known to contain ctenosaurs, as well as examining all known specimens in systematic collections, we found that most populations reported to be C. pectinata were C. similis. On the south-eastern Florida coast, C. similis occurs on Key Biscayne and in Hialeah, Miami-Dade County, and in Davie, Broward County. On the south-western Florida coast, C. similis occurs on Gasparilla Island and in adjacent areas, Lee and Charlotte counties, and on Keewaydin Island, Collier County. Ctenosaura pectinata occurs only along Old Cutler Road on the western side of Biscayne Bay, Miami-Dade County.
