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.

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!

Always follow the Seashore Code when rockpooling, taking care where you walk and making sure you put animals and rocks back gently. The Wildlife Trusts are working with sea users, scientists, politicians and local people towards a vision of 'Living Seas', where marine wildlife thrives.
