Distribution data supplied by the Ocean Biogeographic Information System (OBIS). To interrogate UK data visit the NBN Atlas.
Only coastal and marine records shown



A long, slender, many segmented worm up to 30 cm long and only 4mm in width. It lives permanently in a smooth, flexible, muddy tube that projects up to 10 cm above the sand. The head projects from the tube during feeding and bears a daisy-like crown of feathery tentacles in two groups. The body can be yellowish-orange or greyish purple in colour and the crown is banded in various colours.

Recorded distribution in Britain and Ireland

Widely distributed, and locally abundant, around all British coasts.

Global distribution

Widely distributed in north west Europe.


Found on stones in sand and mud, at and below low water.

Depth range


Identifying features

  • A long, thin worm, up to 30 cm in length and 4 mm in width, with many segments.
  • The body is orange to dull purple in colour.
  • Conspicuous crown of feathery tentacles banded in red, brown and purple, withdrawn into the tube when not feeding.
  • Chaetae small, slender and unobtrusive.
  • The muddy tube is smooth and flexible and projects up to 10cm above the substrate.

Additional information

Identification of the family Sabellidae to species level depends on the fine structure of the parapods (see Fauchald, 1977).
