Crawfish is a common name for several freshwater crustaceans, especially crayfish, and in some regions also for certain marine crustaceans such as spiny lobsters. They are not fish; they are shellfish related to lobsters, crabs, and shrimp. In North American usage, especially in the Southern United States, the term often refers to edible freshwater crayfish.
Name and classification
Crawfish is a regional name for crayfish, which are small decapod crustaceans related to lobsters. Some dictionaries also note a saltwater meaning, especially spiny lobster, depending on the region.
Habitat and ecology
Most crawfish live in freshwater environments such as streams, rivers, lakes, swamps, and muddy or slow-moving waters. They are benthic animals that feed on a mixed diet of living and decomposing plant and animal matter.
As food
Crawfish are widely eaten, often boiled or steamed and served in seasonal boils or seafood dishes. Culinary use is especially associated with the Southern United States, particularly Louisiana.
Regional usage
The word crawfish is used differently by region and can overlap with crayfish or, in some places, spiny lobster. This makes it a common example of regional vocabulary variation in English. In Canada, crawfish is less common than crayfish in general usage, and some Canadian regional dictionaries note unrelated slang or regional meanings in Quebec.
