Elysia sp. from the Line Islands

October 29, 2001
From: Cory Pittman


Dear Bill,
During my recent trip to Christmas Island, Line Islands [Sept 2001], this little Elysia turned up in an algae wash from a shallow reef platform just off the beach in front of the Captain Cook Hotel. It was at less than 0.5 m. At 4.5 mm in length, I suspect it's a juvenile.

Best wishes,
Cory

Dear Cory,
I'm pretty sure this is Elysia mercieri which grows a little bit bigger than this and is usually more green than red. However I don't know of another species that has 3 tufts of gill-like papillae arranged along the parapodial edge like this.
Best wishes,
Bill Rudman
