Each volume employs simple sentence structures to convey basic facts about frogs or snakes, including life cycles, habitats, and feeding information. The excellent photographs showcase a variety of species in vivid detail. Vocabulary-word text boxes and goofy jokes ("What kind of snake never skips dessert? A pie-thon") increase accessibility.
