Frogs are amazingly diverse, ranging from the massive Goliath frog, which weighs several pounds, to the recently discovered gold frog, which measures a mere three-eighths of an inch when fully grown. Frogs have inhabited the earth for more than 200 million years. Today, however, these amphibians face more challenges than any other vertebrate group.
In this informative book, herpetologists Mike Dorcas and Whit Gibbons answer common and not-so-common questions about these fascinating animals. They reveal how frogs and toads evolved, what species currently exist in the world and highlight some that have gone extinct, what they eat and what eats them, the role of frogs in cultures across the globe, and why many frog populations are declining - and what can be done to reverse this dangerous trend.
Mike Dorcas is an associate professor of biology at Davidson College and the author of several books on amphibians and reptiles. Whit Gibbons is a professor emeritus of ecology at the University of Georgia's Savannah River Ecology Laboratory and the author, coauthor, and coeditor of several books, most recently Turtles: The Animal Answer Guide, also published by Johns Hopkins. Gibbons and Dorcas coauthored three other books, Snakes of the Southeast, Frogs and Toads of the Southeast, and North American Watersnakes.
