This work provides a complete account of the exotic reptiles and amphibians of Florida. The authors offer information on the history and nature of each species, the mode of dispersal, and its habitat and geographic distribution in the state at the end of the 20th century. Their impact is measured by their presence in natural systems of Florida and predator-prey interactions with native and other exotic species. Lastly, the role humanity has played in the success of these species is examined.
