Crayfish, also known as crawfish or crawdad, are freshwater crustaceans that resemble small lobsters. They belong to the order Decapoda and are commonly found in rivers, lakes, and ponds. Crayfish have a hard exoskeleton, ten legs, and two large pincers, which they use for defense and capturing food.
These creatures are omnivorous, feeding on plants, insects, and detritus. Crayfish play an important role in their ecosystems by helping to recycle nutrients and serving as a food source for various animals, including fish and birds. They are also popular in culinary dishes, especially in southern U.S. cuisine.
