Usage
What does crawfish mean? Crawfish is another name for a crayfish, a freshwater crustacean related to the lobster but smaller. Crawfish is also sometimes used as the name of several similar saltwater crustaceans, especially the spiny lobster (also called the rock lobster). The plural of crawfish can be crawfish or crawfishes. When used as a plural, crawfish typically refers to them collectively, while crawfishes usually refers to two or more kinds or species (but this isn’t always the case). Crawfish aren’t fish—they’re shellfish. Other types of crustaceans include crabs, lobsters, and shrimp. There are several different species of both freshwater and saltwater crawfish. Freshwater ones are also referred to by the names crawdad and crawdaddy. Use of these terms varies by region. Crawfish can also be used as an informal verb meaning to back out of something or retreat—like a crawfish retreating under a rock. Example: When I was a kid, we used to catch crawfish in the creek.
