In the WorldLife Library series, a compilation of research and scientific studies reveals the anatomy, physiology, and behavior of the world's penguin population. Love, a zoologist, looks at the discovery and history of penguins, their attributes, mating habits, and the conservation of them in a dense, scientific text paired with dramatic full-color photographs. This seemingly awkward flightless bird can be viewed engaging in acrobatic displays while incubating a snowball or pebble in the absence of an egg, or gracefully gliding underwater in ballet-like maneuvers. An in-depth discussion of head ornamentation, body adaptations, metabolic rate of processing oxygen, life cycle, and penguin society raises this above the average animal-fact annals. Most young penguin enthusiasts will have to rely heavily on the photos and captions, passing over some difficult, adult vocabulary and the academic presentation of material. Look to this account as a research tool, not a casual, kid-friendly glimpse at the ever-popular, playful penguin.
