Specimen above found in a sample of coralline turf and sediment sampled from the extreme lowershore, east of the causeway near St. Michael's Mount, Marazion, Cornwall. 19.04.15.
The worm was found in fully saline conditions, no freshwater sources were close to where the species was found. The closest source of freshwater is the stream that enters the sea between the RSPB reserve and Marazion village.
The species here was kindly identified by Ton van Haaren, who stated that the worm was a mature specimen, and that mature specimens were scarce.
