Concerning message #6326:
I've been meaning to send these additional photos of what is now Trapania circinata. We found this second specimen last year and were able to get better photos of it. These new photos of an obviously healthier specimen show that both the anterior and extra branchial process are white with black spots. The middle right photo shows the reproductive system fairly clearly through the translucent white body wall.
Locality: Legan Island, Kwajalein Atoll, 30m, Marshall Islands, Pacific, 13 August 2007, Crawling on sand. Length: 17mm. Photographer: Scott and Jeanette Johnson.

Thanks for the rapid update. The original animal looked like it was rather sick in the photo and I must say I wasn't sure whether the black spots were just an indication that the extra-branchial processes had expanded almost to breaking point. This specimen shows they are apparently a valuable characteristic of the species. I will replace the old photo on the Fact Sheet with this more 'normal' view.
