Ctenosaura Identification Guide
This guide serves as a critical first step for enforcement authorities to implement national conservation laws and CITES regulations regarding spiny-tailed iguanas (Ctenosaura species) of the New World. It addresses the challenge of distinguishing between similar-looking species, which can be difficult even for experienced biologists, particularly with juvenile or recently hatched animals.
The document provides a wide variety of physical forms for the 18 currently recognized spiny-tailed iguana species through photographic identification. While intended as a starting point for inspection, the authors recommend that authorities contact iguana experts for definitive species determinations if questions arise during permitting or shipping processes.
