Cuthona sibogae from the Marshall Islands

June 18, 2001
From: Scott Johnson

Hi Bill,
Here is an eolid I have found in several atolls in the Marshall Islands. I'd identified it as a Cuthona based on the radula (an admittedly very rough sketch is attached). Thanks to the Forum, I think I can now assume it is C. sibogae, even though it lacks the red cerata band below the yellow. The Marshalls specimens are around 10mm or less, and occasionally aggregate on their hydroid prey, which looks like the same one it eats in your area. Both photos were taken at Enewetak Atoll at a depth of about 8 meters, in the shadow of a World War II era concrete barge run up on a reef.
