Book excerpt: Fishermen, marine aquarists, biologists studying seashore and coastal waters, and those involved in trading shellfish and even restaurateurs are aware of the great diversity of crustaceans inhabiting the seas around the British Isles, Northern Europe and the Mediterranean. Crayfishes, Lobsters and Crabs of Europe will enable the reader to identify 42 crustacean species of commercial importance found in these regions during coastal explorations, fishing trips, displayed in public aquaria or available in restaurants, including selected freshwater crayfishes, deep-sea species and some imported species. The book also includes sections on the gross internal and external structure of these Crustacea, their life histories, classification and nomenclature. The book is of interest to students of marine biology and researchers in fisheries science.
