Monkfish (US: angler fish). A fish with a sweet flavour and succulent firm flesh but with the ugliest appearance imaginable. It is found in the Mediterranean and Atlantic, in coastal waters of north western Europe. It can be recognised by its large head and fan-shaped fins. The fins and the operculum are spiny. It can be eaten fried or in soup. The larger fish often have better flavour. It has a hideous head, which is why it is usually displayed without it, and a muddy colour. It is known as the anglerfish as it bears on its head a 'rod' and 'lure' which attract its prey. The meat of the tail is sweet and succulent - almost like lobster meat, entirely compensating for is appearance. The flavour may well be assisted by its own diet which is high in shellfish. The best monkfish are Lophius piscatorius and the similar Lophius budegassa, the favourite of the Spanish. American monkfish or goosefish (Lophius americanus) is considered inferior, while New Zealand monkfish (Kathetostoma giganteum) is related to the stargazer and is only fit for soup.
Lobster. The European lobster is a large, marine shellfish with huge claws and is dark, mottled blue-black before cooking, turning red during the process. The flesh is sweet and tender. The Maine or American lobster found in the United States is huge in size and lacks the wonderful sweetness of its European cousin. American varieties may sometimes be brick red before cooking. In Europe they are likely to up to 2 kg (4¼ lbs) while North American ones may be a lot larger. Increasingly, American lobsters are imported for use in Europe.
Garfish. A striking, beaked, marine fish up to 60 cm (2 ft) long, with a backbone which turns bright green on cooking and a delicious flavour, found on most European coasts.
Crayfish. Spiny or rock lobster. Langouste. A salt water crustacean, not to be confused with freshwater crayfish.
Bluemouth. A type of rascasse from deep North American waters and the western Mediterranean. It has a blue flash on the gill covers and enormous eyes. It is an unsightly fish with good flavour and is used in bouillabaisse and other fish soups.
