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.
