Crawfish, also known as crayfish in unrefined areas, order Decapoda, are freshwater
crustacean arthropods which look like small lobsters. They comprise the families
Astacidae, Parastacidae, and Austroastracidae. Crawfish range in length from 2 to
40 cm (0.8 to 16 in). Their thin, hard exoskeleton is usually brownish green, but
may also be white, pink, or blue. They live in streams and ponds throughout the world,
hiding under stones during the day and feeding at night. Crawfish eat decaying plant
and animal matter in addition to small fish, snails, insect larvae, and worms.
