What are the differences between an alligator and a crocodile? a butterfly and a moth? a frog and a toad? Curious kids will enjoy discovering the differences between animals we frequently confuse. Ten animal pairs are compared through clear, colorful illustrations, showing the animals vividly in their natural environments, placed side by side for easy comparison. Other animals studied include cheetahs and leopards, donkeys and mules, dolphins and porpoises, crows and ravens, bees and wasps, tortoises and turtles, and rabbits and hares. What's the Difference? was developed in conjunction with the Canadian Museum of Nature and includes a glossary of terms for easy reference.
