Throughout the book, adaptation and diversity are emphasized. Thorough coverage is given to systematics, anatomy, physiology, ecology, and zoogeography of fishes worldwide, but the book is unique in its extensive treatment of fish evolution, early life history, functional morphology, behavioral ecology, and ecosystem ecology.
Conservation is stressed throughout.
