Abstract
Ceratostoma ioornatum is an introduced marine snail in Puget Sound,
Washington. Two of five native species tested as possible predators ate
Ceratostoma. These two species, the crabs Cancer gracilis and
Lopbppaoopeys bellys, did not eat native snails similar to Ceratpstpma,
but ate native and introduced bivalves more than Ceratpstpma. The
reasons for the differences in predation seemed to be explained by shell
strength of the prey species. The presence of Ceratpstpma adds a new
type of prey to the menu of the two crab species
at the sites studied.
