From editor or global species database
Depth range Intertidal (British Isles) to 9 m depth (Vostok Bay). [details]
Distribution Northern Europe, Arctic and north-west Pacific (Peter the Great Bay). According to Radashevsky & Pankova (2006: 249) the world-wide records of the boring 'Polydora ciliata' should be verified, since they may include Polydora calcarea. [details]
Editor's comment Polydora calcarea needs to be redescribed with base on fresh material collected at the Belfast Lough. The present disjunct distribution and the reggistered differences in pigmentation suggest the presence of two different taxa. [details]
Habitat Sea of Japan: intertidally and shallow subtidally boring into coralline algae, shells of barnacles and various gastropod and bivalve molluscs. Worms live inside U-shaped burrows with walls lined with fine silt. Each burrow opens to the exterior via two joined apertures forming a characteristic 8-shaped opening. Species occasionally forming aggregations in shells of the bivalves Mizuhopecten yessoensis Jay and Crassostrea gigas (Thunberg) with hundreds of worms in one shell and up to five individuals per square cm of shell surface. Northern Europe: abundant boring in both soft and hard varieties of blue shale, sandstone, calcareous algae, and shells of various gastropod and bivalve molluscs. [details]
Reproduction [Specimens from Vostok Bay] Gonochoristic with almost equal sex allocation. Both in males and females, gametes develop along segmental blood vessels in middle segments, from segments 17-21 to 45-70. [details]
Taxonomic remark Polydora calcarea sensu Radashevsky & Pankova, 2006, from Sea of Japan, variably has black pigmentation dorsally on ~ 4 chaetigers. Such pigment seems not recorded in British Isles Polydora calcarea, although Mustaquim (1986) recorded it on what he identified as P. limicola, and Kendall (1980) on what he identified as P. ciliata. Historic records of pigmentation are possibly be confused beyond resolution by the presence of mixtures of species. [details]
