Coral reefs are among the most dazzling sights in nature. The colorful corals that compose them are breathtaking-- but these habitats are more than just beautiful. They are teeming with wildlife. Brilliantly colored fish with wild shapes and patterns swim in and out of every cranny. Algae help reefs stay alive, and other creatures, such as eels and octopuses, lurk among the corals waiting for prey. In their fifth collaboration, Dorothy Hinshaw Patent and Kendahl Jan Jubb use clear prose and vivid watercolors to reveal the workings of these dynamic and beautiful ecosystems-- from how reefs develop to the wide variety of creatures that inhabit them.
