This large species of ‘nudibranch’ sea slug feeds on a wide variety of sea anemones! They can lay up to 400,000 eggs on the underside of rock in a beautiful ribbon-like formation.
What to look for
This large sea slug usually has grey, brown or fawn colouration. It is covered in lots of floppy projections unique to nudibranchs, known as ‘cerata’. It also has a white V-shaped mark on the front of its head. If you are recording your sightings as part of a recording scheme, make sure to include clear photographs to help verifiers confirm your sighting.
Where to find
Common around the British Isles and Ireland, as well as colder northern waters of Europe

Not only is this sea slug able to eat sea anemones without getting stung, but it can actually reproduce the anemone’s stinging cells into its own body for protection!
