Freshwater crayfish

Freshwater crayfish are freshwater crustaceans resembling small lobsters, commonly found in rivers, streams, and lakes. They play an important role in aquatic ecosystems, serving as both predator and prey. These creatures have a hard exoskeleton, pincers, and a segmented body. They are scavengers, feeding on decomposing material, plants, and small animals. Crayfish are popular in culinary dishes, particularly in southern United States cuisine. Different species exist worldwide, and they vary in size and color, with some being harvested commercially while others are kept as pets or used in aquarium settings.
