Book excerpt: "There are plenty of books about unusual animals. This is a book about fourteen well-known animals--kangaroos, hippos, giraffes--who all have unusual characteristics. For instance, did you know that a kangaroo's kick can be deadly, that a giraffe can clean its own ears with its tongue, or that a hippo has teeth as long as a child's arm? This accessible book, full of amazing photographs and easy-to-digest factoids, is perfect for animal lovers of all ages."--
