|General Biology Additional Information||Size refers to individual worms. It is typically gregarious forming colonies of sheets, hummocks or reefs. In Cornwall, their tubes are up to 20 cm in length and around 5 mm in diameter at the external opening. Each tube has an additional porch over the opening. In northern France, the tubes were reported to grow in length at 12 cm/year.
This species appears to be favoured by elevated winter temperatures associated with cooling water discharges (Bamber & Irving, 1997) but growth is inhibited below 5 °CCommunities associated with Sabellaria alveolata are not particularly remarkable being species poor on young dense reef and up to 38 species on older reefs. Honeycomb worm aggregations that bind together mobile cobbles increase heterogeneity.
