"Animal Eyes introduces young readers to the wonderful, wide-ranging and sometimes downright weird eyes that make up the animal kingdom. The book starts with a crash course in how eyes and vision work -- covering everything from the biology of eyes to the physics of light to the features that protect eyes and keep them clean. Following this is a survey of 40 of the world's most interesting animal eyes, replete with gorgeous full-bleed and inset photos and detailed captions."-- Provided by publisher.
