tenuis appeared to have only simple cilia in the prototrochal ciliary band; among planktotrophic larvae of annelids, simple cilia in the prototroch were previously known only from members of Oweniidae. The anteriormost tier of prototrochal cilia in N.
Most abundant families were Spionidae, Oweniidae, Cossuridae, and Ampharetidae, which accounted for 64% of the total polychaete fauna.
(Oweniidae) was confined to the mudflat and accounted for 43 % of the polychaetes recorded here.

One of the most unusual forms is the mitraria larva of the family Oweniidae. The hyposphere of the mitraria is greatly reduced, and the segmental body develops internal to the larval body as a juvenile rudiment.
A very comprehensive phylogeny of the annelid families Oweniidae, Sabellariidae, Serpulidae, and Sabellidae has been presented by Rouse and Pleijel (2001).
