"hunched over a large bowl of crawfish"

Crawfish are also known commonly as crayfish or crawdads. Crawfish are commonly eaten all over the world but the vast majority are harvested in Louisiana, making them a common food there. Before they are eaten, crawfish are boiled alive in a large pot and seasoned. It is also common for crawfish to be mixed with vegetables and other meats.
