Signal Crayfish
These smooth crayfish with large claws are native to freshwater streams and lakes in Washington, Oregon and Idaho. Signal crayfish lay 200-400 eggs at a time and can live up to 20 years! As they grow, they shed their exoskeletons, eat them, and grow new ones. Birds, fish and some mammals eat them.
