Bifid rhinophores in Elysia crispata

September 12, 2002
From: Anna L. Bass

Note added 30 May 2006: This is most probably Elysia clarki, a new species which was previously considered a colour form of E. crispata

Hello,
Just wanted to share this little creature with you. I found it while snorkeling on the Florida Bay side of the Florida Keys, USA. It was the only individual I saw in the area which was dominated by Halimeda and Bataphora. It is approximately 4cm in length and is still living in a tank. I was curious as to how common the presence of 2 pairs of rhinophores is.

PS: Nick Curtis (USF) took this photo.

Dear Anna,
How is your work going? What an interesting animal. I don't know if it better to describe these rhinophores as 'paired' or bifid. They certainly remind me of the bifurcate rhinophores of the caliphyllids such as Cyerce nigricans and Polybranchia orientalis. Another addition to the Abnormalities List.
Best wishes,
Bill Rudman
