Abstract

Here we report direct underwater observations of the pom pom anemone Liponema multicornis at sites in the western Gulf of Maine. The paucity of records from historic collections as well as recent studies suggest this species is widespread but numerically rare across the region. We found this species hosts high numbers of the commensal amphipod Stenothoe brevicornis amongst the tentacles. In addition, pandalid shrimp were observed using the anemone for shelter by occupying space around the distal edges of the tentacles and as a food source by feeding on bits of mucous. Krill were also observed feeding on amphipods occurring amongst the tentacles. A long history of using bottom contact fishing gear in the region may have reduced abundance, thereby reducing the functional role of L. multicornis as a source for refuge and prey of several crustacean species.
