Daisy anemone (Cereus pedunculatus)

Distribution data supplied by the Ocean Biogeographic Information System (OBIS). To interrogate UK data visit the NBN Atlas.

Summary

Description

The column of Cereus pedunculatus is dark and trumpet shaped, with large, protuberant pale 'suckers' occurring towards the top. Column height is usually up to 12 cm. It is typically a flesh, buff or greyish colour at the base, shading to dark grey, brown or purplish at the top. The oral disc is wide, usually 3-7 cm but can be as wide as 15 cm. Cereus pedunculatus tentacles are short, banded and mottled, numbering between 500 and 1000, and arranged in multiples of six around the oral disc. Colouration in the oral disc and tentacles varies from pale buff to deep purple or black. Often paler around the mouth.

Recorded distribution in Britain and Ireland

Cereus pedunculatus is common on the south and west coasts of Britain but rare on the east coast. Found all round the coast of Ireland, and the southern end of the Isle of Man.

Global distribution

Extends around west coast of Europe from the British Isles to the Mediterranean.

Habitat

Cereus pedunculatus is typically found in pools, holes and crevices, or attached to stones beneath the surface of sediments from the mid shore to at least 50 m depth.

Identifying features

  • Tentacles short, numbering between 500 - 1000.
  • Column trumpet-shaped, up to 12 cm tall.
  • Large, prominent 'suckers' at top of column.
  • Oral disc usually 3-7 cm in diameter.

Additional information

Older specimens of Cereus pedunculatus have a broad central tentacle-free area on the oral disc. Cereus pedunculatus have very similar colouration to Sagartia species. However, the column of Sagartia species is not trumpet-shaped. Only the oral disc of Cereus pedunculatus is visible on soft sand or mud as the column is buried. There is often debris attached to the suckers on column.
