Did you know that a groundhog is really a type of squirrel? That squirrels control their body temperature with their tails? That most squirrels have yellow-tinted eye lenses that work like sunglasses to reduce glare? That tree squirrels can turn their hind feet completely around when climbing down a tree head-first? In Squirrels: The Animal Answer Guide, Richard W. Thorington Jr. and Katie Ferrell unveil the fascinating world of one of the "most watched" mammals on the planet. The diversity of squirrels is astounding. There are 278 species that inhabit all continents except Antarctica and Australia-varying in size from the lumbering 18-pound gray marmot to the graceful pygmy flying squirrel that is smaller than most mice. In many parts of the world they readily share human habitats, joining us for lunch in a city park, raiding our bird feeders, and sneaking into college dorm rooms through open windows. Reviled as pests or loved as an endearing amusement, squirrels have played important roles in trade, literature, and mythology. Thorington and Ferrell cover every aspect of this diverse animal family, from the first squirrels of 36 million years ago to the present day.With over one hundred photographs and an intuitive question-and-answer format, this authoritative and engaging guide sheds light on a common mammal that is anything but commonplace.

"Squirrels of the World", written by scientists with more than 100 years of collective experience studying these popular mammals, is the first comprehensive examination of all 285 species of squirrels worldwide. The authors reveal virtually every detail of the family Sciuridae, which includes ground squirrels, tree squirrels, flying squirrels, prairie dogs, and chipmunks. Each species-from the familiar gray squirrel of American backyards to the exotic and endangered woolly flying squirrel of Pakistan-is described in a detailed account that includes distinguishing characteristics, ecology, natural history, conservation status, and current threats to its existence. "Squirrels of the World" includes: stunning color photographs that document rare and unusual squirrels as well as common varieties; evolution, morphology, ecology, and conservation status; colorful range maps marking species distribution; images of the skull of each genus of squirrel; and extensive references.
