The purpose of this experiment is to determine if sub-lethal predation on Geukensia demissa makes the mussel more prone to predation by the blue crab, Callinectes sapidus. The blue crab uses complex predation strategies to select prey items. The blue crab attempts to maximize net gain and should prefer mussels with previously inflicted shell scarring to intact mussels because the shell is a different color and may be weaker because some of the exterior shell is removed.
