Behavioral traits and territoriality in the symbiotic scaleworm Ophthalmonoe pettiboneae

Abstract Among marine invertebrates, polychaete worms form symbiotic associations showing a wide variety of host use patterns. Most commonly, they live solitary on hosts, likely resulting from territorial behavior, yet little is known of the precise nature of the involved interactions. Based on fiel...
