This book aims to provide the reader with a comprehensive identification guide to all the marine fish you might see as a diver, snorkeller, angler, fisherman, rock-pooler or even beachcomber.
Although focused on Wales, the fish do not recognise such boundaries and the guide includes the waters all round Great Britain and Ireland as all the species featured also occur in these areas, with the exception of some southern and rare visiting fish.
The book covers over 250 species with key identification features and supporting underwater photographs and illustrations. Accounts also cover behaviour, habitat, distribution, natural history and sightings. The book introduction describes how to identify, record and photograph fish and a complete list of UK and Irish marine fishes is included in the appendices.
