A 'crawdad' is a common name for a freshwater crustacean also known as a crayfish or crawfish. They're like miniature lobsters that live in rivers, streams, and lakes. Crawdads are scavengers, eating dead plants and animals, helping to keep the water clean. They're a popular food in some cultures, often boiled or steamed. They are also used as bait for fishing. Crawdads can vary in color, from brown and green to red and blue. They burrow into the mud or hide under rocks.
