The edible crab, or brown crab, is one of Europe’s most commercially important crustaceans, recognized by its distinctive brown pie-crust edged carapace and formidably powerful claws. Found from Norway to West Africa along rocky shores, reefs, and sandy seabeds, these crabs are active nocturnal hunters and scavengers that play a vital role in coastal ecosystem nutrient cycling. They can live for decades, with females able to carry over 3 million eggs in a single brood.
