What are some interesting things about a crayfish?

Crayfish, crawfish, or crawdads are freshwater crustaceans resembling small lobsters, to which they are related. They breathe through feather-like gills and are found in bodies of water that do not freeze to the bottom; they are also mostly found in brooks and streams where there is fresh water running, and which have shelter against predators. Most crayfish cannot tolerate polluted water, although some species such as the invasive Procambarus clarkii are more hardy.On average, crayfish grow to 17.5 centimeters in length, but some grow larger. Some crayfish suffer from a disease called crayfish plague. This is caused by the water mould or mold Aphanomyces astaci. Species of the genus Astacus are particularly susceptible to infection, allowing the more resistant signal crayfish to invade parts of Europe. Crayfish plague is not indigenous to Europe, rather it was introduced by the incorporation of new species of crayfish from the Americas. Different species of crayfish come in variety of colors. Some are found as one solid color, while other species are a variety of colors, such as a blue crayfish with some pink along its shell. They are found in black, brown, red, pink, blue, gray, green, yellow, and purple. Crayfish are kept as pets in freshwater aquariums. They prefer foods like shrimp pellets or various vegetables but will also eat tropical fish food, regular fish food, algae wafers, and even small fish that can be captured by their claws, such as goldfish or minnows. Their disposition towards eating almost anything will also cause them to consume most aquarium plants in a fish tank; however, crayfish are fairly shy and may attempt to hide under leaves or rocks.Well, here are some quick 3 answers or facts#1-Crayfish have several names like claw fish#2-Crayfish can come in 3 different colors such as RED,BLUE,and GRAY.#3-Crayfish normally molt there skin in the middle of June
