Keepers of the Reef

DOWNLOAD Classroom Guide


Coral reefs are the gardens of the sea, and fish are the gardeners. Join two kids and a sea turtle for a journey through a fragile, beautiful ecosystem.


Sharon Wismer—reef ecologist and mom—is the best tour guide a kid could have for a visit to the underwater world of Australia’s Great Barrier Reef. Alice Wong’s richly detailed, accurate watercolors take a boy and girl snorkeling to see the fishes that maintain the ecological balance between the corals and their main competitor, algae. Without the fish species that brush, crop, scrape, excavate, and browse the algae, coral reefs would die. A coral reef is a brilliant and colorful example of how a complex ecosystem functions and why its keystone species are critical to its health.


The Great Barrier Reef is one of Earth’s most celebrated natural treasures. Here children discover why the reef is threatened and what we can all do to help protect it. Keepers of Reef is the rare children’s book combining cutting-edge science with narrative and pictorial magic. Thorough backmatter sources and resources are included.
