    Abstract
    Roatan Spiny-tailed Iguanas, Ctenosaura oedirhina, are listed as Endangered by the IUCN Redlist Assessment and under Appendix II of Convention on International Trade of Endangered Species of Wild Fauna and Flora (CITES). These iguanas occur primarily on Roatan and Barbaretta, off the Caribbean coast of Honduras. Habitat destruction associated with development, small-scale agriculture, and exploitation for food and the pet trade are contributing to the decline of these iguanas. This species was described in 1987 (de Queiroz) when it was split from the sister taxon C. bakeri, found on the island of Utila, Honduras. Since its description little has been done to understand its biology or protect this narrow-range endemic. Herein, I examined the morphology and body condition of this species across its range and report on its reproductive biology and diet. Similar to many members of the Iguaninae, males are larger on average and have relatively longer tails than females. Likewise, reproductive and dietary data are consistent with those for closely related species. The body condition of both males and females was lower in more pristine study sites, indicating that supplemental feeding in developed areas may be having an effect. A female-biased sex ratio was found in sites protected by grassroots efforts, where the populations were large enough to be studied. Conservation measures should focus on alleviating the threats of harvesting and habitat destruction through increased law enforcement, outreach, and education.
