Above specimens were found inside a small, thin plastic, Obelia geniculata, covered container that washed ashore at Perranporth, Cornwall, 30.01.15. There is possible confusion here with Balanus crenatus, which the specimen here looks like. Balanus crenatus being a common fouling species. Images were sent to Ian F. Smith as the species didn't exactly fit with B. crenatus. Ian kindly determined the species to be Semibalanus balanoides.
