Coral reefs are the rain forests of the ocean! Scientists estimate that about one-quarter of all ocean species depend on coral reefs for food and shelter. This means coral reefs are a great spot to find many different species of plants and animals. Readers will explore colorful coral reefs and find creatures that don't exist anywhere else on Earth. Full-color photographs show readers how beautiful reefs are, while fact boxes provide them with additional information about why we need to keep these habitats safe.
