"In this comprehensive guide, [Spotila] treats in detail the seven species: green turtles, hawksbills, olive ridleys, Kemp's ridleys, loggerheads, flatbacks, and leatherbacks. Each chapter includes tables of data on where the species is found, population estimates of colonies, and, in some cases, a chronology of conservation efforts... Spotila, fittingly, offers vignettes of conservation projects that provide human interest... Spotila's book is recommended for high school, university, and research-level libraries."
