Definition

Noun: * Large edible marine crustacean: A type of large, edible sea creature with a hard outer shell (exoskeleton). It is characterized by a spiny carapace (the hard upper shell covering the main body) but does not possess the large, prominent pincers or claws that are typical of true lobsters.

Usage

• This term specifically refers to the animal itself, often in the context of marine biology, fishing, or as a type of seafood.
• It is a compound noun where "sea" specifies the habitat and "crawfish" identifies the type of crustacean. The term is used to distinguish this spiny, clawless marine species from freshwater crayfish and from true lobsters.

Examples

• The diver observed a sea crawfish hiding among the coral reefs.
• Sea crawfish is a popular delicacy in many coastal regions.
• Unlike the American lobster, the sea crawfish lacks large claws.

Advanced Usage

• The term is often used interchangeably in common language with spiny lobster or rock lobster, which are more precise common names for this group of crustaceans.

Variants and Related Words

• Spiny lobster (noun): The most common alternative name for a sea crawfish, referring directly to its prominent spines.
• Rock lobster (noun): Another common name, often referring to species that inhabit rocky ocean floors.
• Langouste (noun): A French culinary term for spiny lobster, sometimes used in English menus.
• Crayfish (noun): Typically refers to smaller, freshwater crustaceans that often have claws, which can cause confusion with "crawfish."

Synonyms

• Spiny lobster
• Rock lobster
• Langouste (in culinary contexts)

Different Meanings

• Crawfish (or crayfish) alone, without "sea," most commonly refers to small, clawed freshwater crustaceans, not the large marine animal.
• Lobster typically refers to clawed lobsters (e.g., American or European lobster), which are different from the clawless sea crawfish.

Noun

1. large edible marine crustacean having a spiny carapace but lacking the large pincers of true lobsters
