In this poetic exploration of the five vertebrate classifications mammals, birds, reptiles, amphibians, and fish animals come to life in lush color. "Elephants to pygmy wrasses, vertebrates are grouped by classes." Each class gets the spotlight in breathtaking digital woodcut art accompanied by rhythmic, kid-friendly poetry. With a focus on trademark characteristics, such as birds' beaks or the scales of fish, the book explains the differences between the five classes. Back matter includes an index and a glossary of scientific terms, as well as a table with information and examples from each classification for cross-referencing.".
