Crawfish, sometimes called crayfish, are similar to lobsters but much smaller. Crawfish are most commonly found in Louisiana, and they are eaten there as a part of southern cuisine, or Cajun cooking. Crawfish are tender and usually boiled but they need to be cleaned first, which is referred to as purging.
Like all crustaceans, crayfish are not kosher because they are aquatic animals that do not have both fins and scales. They are therefore not eaten by observant Jews.
