From tiny rats and bats to giant elephants and blue whales, our planet is home to an incredible variety of mammals. Featuring almost 200 profiles of individual species as well, Pocket Genius: Mammals looks at humans, whales, wallabies, camels, and more, highlighting facts on anatomy, behavior, diet, habitats, and classification, plus extinction and conservation efforts to save endangered species. Redesigned in paperback, DK's best-selling Pocket Genius series is now available in an engaging compact and economical format that is ideal for both browsing and quick reference for use in school and at home. Catalog entries packed with facts provide at-a-glance information, while locator icons offer immediately recognizable references to aid navigation and understanding, and fact files round off the book with fun facts such as record breakers and timelines. Each pocket-size encyclopedia is filled with facts on subjects ranging from animals to history, cars to dogs, and Earth to space and combines a child-friendly layout with engaging photography and bite-size chunks of text that will encourage and inform even the most reluctant readers.
