"Characterized by the bony shell that acts as a shield to protect the softer body within, turtles are survivors from the time of the dinosaurs and are even more ancient in evolutionary terms than snakes and crocodilians e than 350 species known today, some are highly endangered. In this beautiful guide, turtle families, subfamilies, and genera are illustrated with hundreds of color photographs. Each genus profile includes a population distribution map, a table of information, and commentary that includes notable characteristics and discussion of related species."--
