Janolus cristatus from Cornwall, UK

November 3, 2005
From: Judith Oakley


Dear Bill,
These two colourful specimens were found on a marine pontoon in Falmouth, Cornwall, UK. This is the first time that I have come across the species and I was amazed by the colourful spots on the sides of the foot.

Locality: Falmouth Marina, Cornwall, UK. Length: 45 mm. 26 October 2005. On marina pontoon . Photographer: Judith Oakley

They were located amongst bryozoans growing on kelp.

Dear Judith,
You are certainly finding a good selection of nudibranchs in this habitat. As would be expected most feed on fouling organisms such as bryozoans and ascidians. I have included a close-up alongside of the head region to show the raised 'common trunk' region of the rhinophores, with the wrinkled caruncle, which is a unique character for the genus, between the rhinophores.
Best wishes,
Bill Rudman
