Spurilla neapolitana. A 'groundbreaking' sea slug discovery has been made - in a UK first. The nudibranch Spurilla neapolitana, typically found in much warmer climates, has been discovered in Cornwall. The colourful sea slug is a usual resident in the Caribbean, Mediterranean, and along the western Atlantic. Until now, its most northerly sighting was in Brest, France, in August 2025.
