Crawfish may not always look appetizing, but it is actually a delicious and nutritious type of seafood to add to your diet!

What is Crawfish or Crayfish?

Crawfish, also known as crayfish, are small crustaceans, from a variety of families in the Arthropoda phylum, which looks similar to lobsters. They usually only grow to about 3-4 inches long, and nearly all live in freshwater environments. As crustaceans, they are considered shellfish by the food and fishing industries and are extremely good for your overall health. Many species are found exclusively in North America and are particularly abundant in Louisiana and Mississippi, where they feature heavily in the local cuisine.
