|Recorded distribution in Britain and Ireland||Common and widespread on all coasts.|
|Habitat information||Pomatoceros triqueter encrusts stones, rocks and shells, and the carapace of some species of decapods. They are predominantly sublittoral to depths of 70 m.|
|Description||The calcareous tube of Pomatoceros triqueter is 3.5 mm wide and up to 25 mm long. It is white, smooth and irregularly curved with a single, median ridge that ends in a projection over the anterior opening. The operculum bears a shallow, dish-shaped plug (ampulla) which is often conical distally, and may have projections on the crown. The colouration of the body is bright but variable, and the crown of tentacles (radioles) are banded with various colours.|
