Map icon Recorded Distribution in Britain and Ireland A very rare species in the British Isles with isolated records in the Shetland Islands and Loch Eriboll, Scotland. These localities probably reflect the southern limit of this species.
Habitat information icon Habitat information This species lives on seaweed, ascidians, shells and stones at depths of 5 to 230 m.
Text page icon Description Colonies form small round patches and encrust hard surfaces. Zooids are small (0.50 to 0.63 mm in length by 0.3 mm in width) and rhombic or oval in shape. The frontal surface is slightly raised with numerous pores. The primary orifice is located at the top (distal) end of the zooid, is round and completely encircled by a calcified elevated ridge (peristome). The peristome orifice is circular with a series of projections at various intervals. A semi-circular pore is situated at the base of the peristome. Young zooids located at the margins of the colony have 4 thin, long spines at the distal margin of the primary orifice. Ovicells are present and are round and raised with the surface covered in small pores. There are no avicularia.
Identifying features
  • Colonies form small round patches.
  • The frontal wall of the zooid has numerous pores.
  • The peristome extends from the primary orifice and has a small hole at the base.
  • A series of points often project from the rim of the peristome.
  • Ovicells are present and situated behind the primary orifice.
  • Zooids are oval or rhomboidal in shape.
