Dear Nick,
Your photo also contains something else of interest. When I decided to cut out part of your photo (alongside) to show the closed up gill pocket I noticed that the Ceratosoma was home to an infestation of little crustaceans called copepods [see symbiosis Fact Sheet]. The easiest one to see is the one in the front left side of the photo. It has two white tail-like structures which are in fact its egg sacs. I think I can make out about 5 copepods in this close-up. The photo also shows the volcano-like structure, which is the tightly closed gill pocket.
Best wishes,
Bill Rudman
