Have you heard of a cave squeaker frog? A mustache toad? How about a Pinocchio frog? An introduction informs the reader that there are thousands of species of frogs inhabiting every continent except Antarctica. To illustrate the variety, the book opens with a selection of species pictured at one-half life size, ranging from the meowing night frog (about the size of a human thumbnail) to the ornate horned frog (roughly the size of an adult human hand). A diagram of defining frog characteristics follows, including differences between toads, which are a type of frog, and other frogs. From there, the guidebook moves through a broad exploration of this animal, using different species as examples: Mating behavior, life cycle, habitat, diet, defenses, and threats against the species’ survival. Colorful cut- and torn-paper illustrations show several unique frogs on each white page, with snippets of fascinating information accompanying each specimen. (Ages 4–8)
