An individualbased model which incorporated information about incidence of snail shell scarring (resulting from non-lethal interactions) and snail density, predicted reduced predation rates and smaller average crab size with distance from the low tide refugium for crabs. We studied size-structured predator-prey interactions between blue crabs (Callinectes sapidus) and marsh periwinkles
