This book is the only comprehensive account of the lizards of the genus Sauromalus. It provides detailed descriptions of their care and breeding in terrariums, as well as their behavior in the wild, accompanied by numerous photos. These fascinating animals are perfectly adapted to dry, hot habitats as desert dwellers, and particularly the males of certain populations are strikingly contrasting in colors of black, red, or white. Observing Chuckwallas basking on exposed rocks in the Arizona desert is an impressive experience.
