The juvenile specimen above was found on sifting fine sand in pools on the lowershore at Albert Pier reef, Penzance, Cornwall. 25.08.17.

This nemertean had been turning up in sand samples for a few years and as I was near to identifying it myself I approached the British nemertean expert Ray Gibson to see what his thoughts were. He said it was likely Carinesta anglica but repeated what his synopses 'British Nemerteans' says, that the worm is only known from one specimen from the River Yealm in Devon, and from a fragment of worm from Whitsand Bay, Cornwall. He was unable to confirm the species because internal characteristis are important in validating the species, hence why it has a question mark beside it's name above.
