Crayfish are freshwater crustaceans that live in streams, rivers, and lakes. While they can be found practically everywhere in the world with these conditions, crayfish are most abundant in the United States/ North America. Crayfish eat decaying plants, dead fish or insects, and living plants. Like fish, crayfish have gills that they breathe through in order to obtain oxygen that is then dissolved into their bloodstream. One fun fact is that there are many different unique colors of crayfish that can be found such as bright blue, green, and orange.
