About Habitats: Coral Reefs

This beginner’s guide introduces coral reefs to young learners (PK-2) and showcases the diversity of wildlife found around the world in these complex ecosystems

ABOUT HABITATS: CORAL REEFS is an engaging first glimpse into this unique habitat. In simple terms, author and former teacher Cathryn Sill explains what corals are and how reefs are built, describes the characteristics of some of the world’s major coral reefs, and highlights some of the many species of animals and plants that have adapted to life in these fragile environments. Detailed illustrations by award-winning wildlife artist John Sill depict a variety of coral reefs, from the Great Barrier Reef in the Pacific Ocean to the Red Sea Reef in the Indian Ocean. The colorful, detailed paintings bring the coral reefs to life for young naturalists.

A map, an afterword, and a glossary provide more detailed information about coral reefs in general and about the wildlife featured in the illustrations.
