Concerning message #17145:

Bill and Willfried,
I suggest you consider Calma glaucoides as the ID for this specimen. It has a variable appearance but the cerata clusters are arranged distinctively and argue against a cuthonid. I attach a photo of a well fed, large UK specimen but Bernard Picton's website shows a less superficially pigmented form.

Locality: Penzance, 15m, Cornwall, Atlantic UK, August 1977, unknown. Length: 23 mm. Photographer: finder unrecorded, photo Greg Brown.

Dear Greg,
Thanks for the suggestion. Looking at Gonçalo Calado's photo [message #8267] of a juvenile Calma glaucoides, I can see the same ceratal arrangement and triangular oesophageal-stomach region. I guess I expect C. glaucoides to have the characteristic 'bunches of grapes' white gonad down each side of the dorsal midline, but the gonad is not really visible in juveniles.

Best wishes,
Bill Rudman
