Elysia obtusa from the Marshall Ids

From: Scott Johnson
Hi Bill,
Elysia obtusa also occurs in the Marshall Islands, where I have found it in Enewetak, Bikini, and Kwajalein Atolls. I thought of this photo when Kathe mentioned Derbesia, but the brown filaments in the picture don't appear to me to be closely related to Bryopsis, so I presume it is something else. I do not recall seeing the Elysia eating this or any other algae. The animals here are generally found hidden away under rocks during the day.

Your alga looks like a red to me. Your observation about it hiding under rocks during the day fits with Julie Marshall's observations.
Cheers,
Bill Rudman
