Proceraea okadai
Taxonomic Group: Annelids-Polychaetes


Proceraea okadai is a Syllid polychaete. It is thought to be native to Japan, where it was first described. Introduced populations are known from Friday Harbor, Washington and San Francisco Bay, California. In both locations, individuals were found amongst benthic fouling species (sponges, hydroids, barnacles) on floating docks and piers. Like other Syllids, it reproduces by epitoky. During epitoky its body breaks into segments, some of which become modified for carrying gametes and swimming. No impacts have been reported from introduced populations.
