Grades 2-4. This attractive, large-format volume introduces eyes in the animal kingdom. Large, colorful, and sometimes arresting, the illustrations will draw many young children, but they will find the vocabulary and concepts challenging. While the introduction briefly discusses the history and types of eyes, it does not provide the basic background that kids will need to understand the information given later. A typical entry features one animal on a page or a double-page spread. Jenkins seeks to amaze and inform with factoids, such as that the basketball-sized eyes of the colossal squid can detect the faint glow of tiny bioluminescent creatures when they are disturbed by an approaching sperm whale, the squid’s archenemy. The writing seems complex for the intended audience, but the artwork is handsome and well composed; each image is a subtle, intricate paper collage. There’s no indication of the animal’s actual size until the back matter. Still, browsers will enjoy the illustrations, while teachers might find this a useful visual resource for showing a wide variety of animal light-sensors and eyes.
