Turtles are a species of reptile at its evolutionary zenith, with an ancient lineage stretching back over 200 million years. Under their unmistakable shells, testament to their survival, they harbor a natural history of epochal proportions. This is the engrossing story Turtles tells. The book offers a full account of the evolution, history, diversity, ecology, and behavior of the turtle, and of the problems facing these reptiles worldwide. The book describes the important role turtles play in their ecosystems, as well as the pressures put upon current populations by habitat destruction, over-collection for the pet trade, and increasing consumption for food.
