Dr. Murphy follows the changes in zoo and aquarium communities by looking at the development and expansion of the discipline, the evolution of ideas which led to greater conservation awareness and activity, vignettes of interesting historical moments, and pioneers in zoo herpetology. Portraits of a selected number of zoos and aquariums throughout the world are presented to show the chronology of herpetological discovery, people who worked at those places, and the breadth of the programs that were put in place.
