A beautifully illustrated photographic identification guide to the marine crustaceans of Britain and Ireland—essential for divers, snorkellers and beachcombersCrustaceans are a diverse group of animals found all around the coasts of Britain and Ireland, from beaches to deep offshore waters. This field guide offers a practical, easy-to-use approach for identifying the crustacean species commonly seen in the region. The book’s incisive text and informative diagrams highlight key identification features and are accompanied by numerous photos of each species in its natural environment wherever possible. It also clearly explains when species identification is not possible, indicating an appropriate taxonomic level in such cases. Published in association with the UK’s Marine Conservation Society, Marine Crustaceans of Britain and Ireland is an invaluable addition to the series of marine photographic titles of Seasearch, a long-standing species-recording project for volunteers.
