Locality: Diamant, 15 m, Martinique (French West Indies), Caribbean Sea, 23 February 2007. Length: 20 mm. Photographer: Stephane Ores.

Thank you for help

Dear Stephane,
I am pretty sure this is the gorgonian-feeding Tritonia hamnerorum. The only difference I can see externally is the presence of orange-red on the rhinophore sheaths, the gill stalks, and as a faint band on the tentacles on the oral veil. Other aspects of the colour are identical, as is the relative size of the gills, shape of the body, and number of tentacles on the oral veil.

I would be interested in comments from anyone familiar with T. hamnerorum or this red marked 'form' or 'species'.

Best wishes,
Bill Rudman
