Life-history patterns in serpulimorph polychaetes: ecological and evolutionary perspectives
Information on the life history of tubeworms (Serpulidae and Spirorbidae) is summarized to clarify the direction of life-history transitions in this group and determine whether phylogenetic constraints can account for the observed life- history patterns.

A new species of the genus Sabellaria Lamarck, 1812, is described from shallow waters off Onjuku, the Pacific side of Boso Peninsula, Chiba, Japan, and is distinguished by the character combination of having 1 or 2 pairs of nuchal spines.
Phylogenetic analyses of Chaetopteridae (Annelida)
Chaetopteridae was monophyletic in the molecular phylogeny, and united by a number of morphological features, including a single pair of grooved peristomial palps, three morphologically distinct tagmata (A, B, C) and the presence of stout, modified cutting chaetae on anterior chaetiger 4 (A4).
