Egg: Nature’s Perfect Package

This nonfiction picture book explores eggs across a wide range of animals. It explains that insects, spiders, amphibians, birds, most fish and reptiles, and two mammals—the echidna and platypus—lay eggs. Different spreads examine egg size, where animals lay eggs, how many they produce, and the ways eggs are guarded, buried, carried, or left alone. The book also looks at egg casings, threats, incubation, and hatching. A visual index adds information about more than 50 featured species.
