125 million years ago on the floodplains of North America, a burrowing lizard started down the long evolutionary path of shedding its limbs. The 60-plus species of snakes found in Sean P. Graham's American Snakes have this ancestral journey to thank for their ubiquity, diversity, and beauty. Although many people fear them, snakes are as much a part of America's rich natural heritage as redwoods, bald eagles, and grizzly bears. Neither a typical field guide nor an exhaustive reference, American Snakes is instead a fascinating study of the suborder Serpentes. Brimming with intriguing and unusual stories- of hognose snakes that roll over and play dead, blindsnakes with tiny vestigial lungs, rainbow-hued dipsadines, and wave-surfing sea-snakes- the text is interspersed with scores of gorgeous full-color images of snakes, from the scary to the sublime.
