Eubranchus tricolor - strange form

April 15, 2006
From: Jim Anderson

Dear Bill,

The animal was ID'd for me by Bernard Picton who commented,

"I've seen individuals with this bare back and extra swollen cerata on Tubularia, I suspect that getting stung by the Tubularia induces this atypical appearance, but I could be wrong and they could be a different species altogether. No way to tell, except DNA I guess."

Locality: Bogha Na Fionn-Aird, Island of Muck, 12 m, Scotland, Atlantic Ocean, 9 April 2006, vertical rocky reef. Length: 15 mm. Photographer: Jim Anderson.

Kind regards,

Jim A

Dear Jim,
The pericardial region [over the heart] does seem very swollen. Perhaps they have a parasite in their?
Best wishes,
Bill Rudman
