Turtles in Your Pocket


Book Description

From the hefty alligator snapping turtle—the largest freshwater turtle in North America and the only turtle in the world with a predatory lure in its mouth—to the wood turtle, which uses “worm stomping” to catch earthworms, to the lovely ornate box turtle, which closes its shell completely for self-defense, the slow-but-sure turtle is an intriguing reptile. Terry VanDeWalle provides a complete description of each species, both male and female, along with distinguishing characteristics for fourteen subspecies, information about range and habitat, and natural history notes about behavior, hibernation, diet, and nesting. Two panels devoted to hatchlings provide short descriptions of the young of each species as well as photographs of some commonly seen young turtles.
