The preeminent naturalists Albert Hazen Wright and Anna Allen Wright spent years assembling the wealth of material on frogs and toads appearing in this widely used handbook, the third edition of which was originally published in 1949. With abundant black-and-white photographs, colorful descriptions, journal notes from the field, and excerpts from the literature, their personalized natural history emphasizes amphibians observed in the wild. In a foreword to the 1995 paperback edition, Roy McDiarmid, a foremost specialist on frogs and toads, brings the book into historical perspective and supplies information to bring it up to date. Accounts of more than 100 species and subspecies cover such topics as common and scientific names, range, habitat, size, and general appearance, as well as color, structure, voice, and breeding. Separate keys are given for secondary sexual characteristics, eggs, tadpoles, families, and species. Generous quotations from the Wrights' field journals give the reader a sense of the problems and satisfactions of their work.

Florida contains more exotic amphibians and reptiles than any other U.S. state. Illustrated species accounts detail the history and nature of each, the mode of dispersal, natural history, and present-day habitat and geographic distribution in the state. The impact of these animals is measured by their presence in natural systems of Florida and predator-prey interactions with native and other exotic species. The authors update the list of the documented exotic species in Florida and provide a progress report on new and published natural history information for each established species. An afterword examines the role people have played in the success of these species.
