This comprehensive field guide addresses the challenge of identifying the vast diversity of fish species encountered by divers and researchers within the coral reef ecosystems of the Indo-Pacific and Caribbean regions. Authors Ewald Lieske and Robert Myers leverage their expertise in marine biology to provide a systematic identification framework for over 2,000 species. The text synthesizes morphological data, geographical distribution, and habitat preferences to assist observers in accurately cataloging marine life in the wild.

The subject matter points to a highly specialized, technical reference tool designed for marine biologists, professional divers, and serious naturalists. Its extensive cataloging and focus on visual identification markers suggest a standard, authoritative resource for field research in tropical marine environments.
