AB  - The polychaete <i>Polydora colonia</i> is a widely distributed symbiont of sponges that has been reported as introduced into the Mediterranean Sea. <i>Polydora colonia</i> is re-described based on specimens associated with the sponges <i>Microciona prolifera</i> and <i>Halichondria bowerbanki</i> from New York and aspects of its reproduction and feeding biology are described for the first time. The morphology of <i>P. colonia</i> agrees with previous reports of this species. Females of <i>P. colonia</i> deposited egg capsules (14-19 eggs/capsule) in their tubes on sponges and adelphophagy was observed. Larvae appear to be competent to settle on hosts at the 13-chaetiger stage. One commensal ciliate and one parasitic copepod were found associated with <i>P. colonia</i>. <i>P. colonia</i> as an introduced species is evaluated based on current evidence. Sponge material was observed in the gut of >50% of the worms examined but further studies are needed to evaluate whether <i>P. colonia</i> is selectively feeding on <i>M. prolifera</i>.
