Harmful Aquatic Hitchhikers: Crustaceans: Rusty Crayfish:
"Rusty crayfish can be identified by their robust claws, and by dark, rusty spots on each side of their carapace. The spots are located on the carapace as though you picked up the crayfish with paint on your forefinger and thumb. The spots may not always be present or well developed on rusty crayfish from some waters."
