What is the Difference Between Crayfish and Crawfish?

Crayfish, crawfish, and crawdads are the same animal, which are freshwater crustaceans resembling small lobsters. The difference between these terms arises from regional preferences in different parts of the United States and the world. Here are the common usage areas for each term:

• Crawfish: This term is most commonly used in Louisiana and other southeastern states in the United States.
• Crayfish: People in the northeast and far north of the United States, including parts of the Pacific Northwest and the Midwest, are more likely to use this term.
• Crawdads: This term is primarily used in scattered areas with smaller populations, such as Northern California, Oregon, Kansas, Missouri, northeast Kentucky, and West Virginia.

In addition to these regional variations, the term "mudbugs" is also used in the Mississippi Delta. The term "crawfish" comes from the Old French word "escrevisse," which has been modified over time, while "crawdad" and "mudbug" are derived from these original words to give more local flair.
