Crayfish/Crawldads

Crayfish are part of a group of animals called crustaceans, which have hard outer shells or exoskeletons. They have two pair of antennae and generally breathe through gills. Other examples of crustaceans include: shrimp, crab, and lobster. 
Crayfish, which look like little lobsters, have five pairs of legs, with the front pair modified as claws with pincers. They use these pincers for feeding and defense. They occur in ponds, rivers and streams, and even wet meadows. Crustaceans are omnivores, feeding on plants, as well as both living and dead animals. They take shelter under stones or debris in the water and use their tails to propel themselves backwards away from danger.
