What is a "crayfish"?

A crayfish, also known as a crawfish or freshwater lobster, is a small crustacean resembling a miniature lobster. It is found in freshwater habitats such as rivers, streams, and lakes. The crayfish has a segmented body, a pair of large pincers, and multiple legs. It is known for its ability to burrow into the substrate and create intricate tunnels. Crayfish are omnivorous, feeding on plants, insects, small fish, and decaying organic matter. They are an important part of the aquatic ecosystem and are also consumed by humans as a delicacy in many cuisines.
