Systematics and Ecology of Shell-Boring Polychaetes from New England

In a survey of shell-boring polychaeles of New England, representativesof five families were found: Spionidae, Cirratulidae, Capitellidae,Terebellidae, and Sabellidae. The five spionid species were studied extensively. These includePolydora commensalis Andrews, found only in shells occupiedby hermit crabs, P. concharum Verrill, P. socialis (Schmarda), P. websleri Hartman, and Boccardia hamata (Webster) , foundin various types of shell. Breeding periods were defined andthe larval development described for each species. Polydoraconcharum deposits egg capsules inwinter months, while the oilierpolydorids spawn in spring or summer. Morphology of planktoniclarvae is distinct in each species, although P. websteri larvaemay be confused with non-boring species such as P. ligni Webster.Polydora socialis adults are found in both shells and sedimentand have a unique grinding apparatus, a gizzard, between theesophagus and intestine. The cirratulid, Dodecaceria sp., follows an asexual mode ofreproduction. The syslematics of Dodecaceria is complex owingto multiple modes of reproduction. No sexually mature individualswere observed during the course of this study. Asexual budswerefound in the Fall. A sabellid, Pseudopolamilla reniformis (Miiller), is commonlyfound in theshells of Placopeclen magellanicits (Gmelin) inMaine waters. Its reproductionis unknown.
