Bornella from Colombia

From: Alexander Taborda M.

Dear Dr. Rudman,
Could you please help me with the identification of this organism. Is it Hancockia sp.? It was collected at 20 metres depth in a bottom trawl in Santa Marta (Colombia - Caribbean). Length 3cm.

Thanks for your collaboration.

Dear Alexander,
From the shape of the animal, and the radula, this is a species of Bornella. The only species reported from the Caribbean is Bornella calcarata so that is the most likely identification.

Although Hancockia is somewhat similar in external shape, the dorsolateral processes are not stalked cerata like in Bornella, and the radula is triseriate - that is it has a central tooth and only one lateral tooth on each side.
Cheers,
Bill Rudman
