This book explains the science of coral reefs, including how they have evolved, what determines where they grow, their composition, the different zones on a reef, the different types of coral reef and how they feed, grow and reproduce.

It looks in detail at coral reef organisms, including vertebrates, invertebrates and fish. It also describes coral reef plants and algae.

The book analyses the threats to coral reefs (including natural threats, human threats and climate change) and considers their future.

The author, Orla Doherty, Director of Biosphere Foundation, presents her observations from the Biosphere Foundation’s expedition to map and monitor the world’s coral reefs.
