Bold cut-paper illustrations show black-and-white killer whales in water of vivid blue. The main text follows a baby whale from birth (“already as big as a large refrigerator!”) to maturity, when he reaches his adult size at twenty years of age. Facts set apart in blocks of bright pink and printed in a smaller typeface define terms such as “blubber” and “breaching,” and describe specific whale behavior. The final pages of the book include a map showing where killer whales live, a few additional “fun facts,” a glossary, and suggestions of books and a website to explore for more information. (Ages 4–8)
