Understanding the morphological basis of intraspecific variation in drilling ability on rocky shores
Abstract
Due to the open nature of marine ecosystems, there is a lack of research on intraspecific trait variation. However, recent studies have found that phenotypic variation in predators may be a result of prey-driven selection. We examine this dynamic in the channeled dogwhelk, Nucella canalicultata. This carnivorous snail preys on mussels and barnacles along the West Coast of North America by drilling a hole through the shell of its prey to feed. Previous research suggests that populations of N. canaliculata vary in their drilling ability. In this study we investigate intraspecific phenotypic variation in the form of drill hole area.
