Summary

Description

A tubeworm between 4-5 mm long and with ca 30 body segments. The body is pink with a colourless, white or pinkish crown of 8 tentacles. Salmacina dysteri live in delicate, calcareous tubes that are almost translucent white and up to 0.5 mm in diameter. These worms occur in dense aggregations that interweave their tubes in a rope-like mass.

Recorded distribution in Britain and Ireland

Common around the British Isles.

Global distribution

-

Habitat

Occur on rocks and may be found on the lower shore, but more commonly occur sublittorally in less sheltered areas.

Depth range

-

Identifying features

  • Dense aggregation of interwoven tubes.
  • Tubes white, almost translucent.
  • Eight colourless, white or pinkish tentacles on the head.
  • Body pink and up to 5 mm long.

Additional information

Almost identical to the tubeworm Filograna implexa. The two species can be distinguished by the cup-shaped terminals (opercula) to two of the crown tentacles present in Filograna implexa, which are absent in Salmacina dysteri. Salmacina dysteri may form large globular masses which divers have described as "like brain coral".
