Life History and Ecology of the Five-Lined Skink by Henry S. Fitch is a textbook about a species of lizard in the family Scincidae. The species is endemic to North America.

Excerpt: "Skinks were obtained by active search; rocks and boulders were lifted and the skinks thus exposed were seized by hand before they had time to escape."

This book is an in-depth look at the natural history of each snake and lizard species/subspecies found in Iowa. Each of the thirty-three species accounts includes a sampling of the common names the species has been known by in the past, the first specimens collected in the state, and a brief history of the early Iowa literature related to the species, along with a complete description and a discussion of similar species, distribution in the state, habitat, behavior, threats, foods and feeding, and reproduction. While readers will be able to identify Iowa’s snakes and lizards through its species accounts, identification keys, and beautiful photographs and illustrations, this book is intended to be more than a field guide. What makes it truly unique is the comparison of historic data collected by Iowa herpetologists in the 1930s and 1940s with data collected by the author, along with James L. Christiansen and others, since 1960. Custom maps show the reader how species’ distributions have changed over time.

Providing thorough descriptions of almost 200 species, this guide presents thousands of facts and figures that will help you identify, understand, and appreciate these important and remarkable animals. Each species and subspecies account includes the latest findings on abundance, size, reproductive habits, prey, habitat, behavior and venomous/nonvenomous status.
