Range & Status
A warm-water species apparently restricted in Britain to the Channel Islands, Cornwall and the Isles of Scilly. Recorded from Polridmouth, the Isles of Scilly, and Gulland Rock, Padstow. A benthic species, found in low eulittoral and shallow sublittoral down to 25m off Bryher (Isles of Scilly); a very small worm forming a translucent coiled tube some 2mm across; found on the lower sides of rocks in clear waters which are free of silt and sand.
