Imagine a worm that lights up like a tiny toy train. There's a bright red light on the worm's head! Beetles blink codes to each other using lanterns in their tails. And some kinds of fish have built-in headlights to help them make their way through the murky ocean. All these light-producing creatures are using bioluminescence. With color photographs and diagrams, this book shows how fish, glowworms, fireflies, and other insects and marine creatures use this light. Some creatures light up to communicate, while others do it to camouflage themselves, lure prey, or frighten enemies. The book features an explanation of what causes bioluminescence.

Discovering Underwater Secrets with a Nature Photographer Patricia J. Murphy
Published by Enslow Publishers, 2008.
Patricia Murphy introduces young readers to nature photographer Norbert Wu. Take a breath-taking look at his underwater world, from the blue waters of the Bahamas to Australia's Great Barrier Reef. How does he take photos under water? How can he swim under the ice in Antarctica? Readers will learn about Wu's fascinating career and understand how his images help show how the oceans need better care.
bioluminescence Emission of light by living organisms, such as fireflies, glowworms, and certain fish, jellyfish, plankton, fungi, and bacteria. It occurs when chemical compounds react and give off light.
camouflage Protective coloring or other appearance that conceals an animal and enables it to blend into its surroundings.
ecosystem An ecological community made up of plants, animals, and microorganisms together with their environment. A pond or a rain forest are each examples of complex ecosystems.
