Ceratosoma miamirana from Papua New Guinea

Dear Bill,

I believe these are both Ceratosoma miamirana.

UPPER PHOTO: This brown one was sitting on a brown sponge on top of a coral bommie near Sanaroa Island, Milne Bay Province, Papua new Guinea. Depth: 9 meters, length: 75 mm. May 22, 2000
LOWER PHOTO: This lighter colored one is from Luadi, Milne Bay, Papua New Guinea. It was about the the same size, 4 meters deep, on a sandy bottom with patch reef. March 1, 1999.

These are the only two I have seen. I think they are very beautiful animals.
Regards,
Mary Jane

Dear Mary Jane,
I agree that these are beautiful, especially the colours on the underside of the mantle and the foot (See top of page).

I am very interested to see the brown animal on the brown sponge which looks very much like a dendroceratid sponge of the family Halisarcidae which form a tough leathery, almost slimy layer over rocks or other hard surfaces, looking more like a compound ascidian than a sponge. This is the type of sponge that Actinocyclus and some species of Hallaxa feed on. It would be interesting to know if C. miamirana is just passing across this sponge or feeding on it.

Best wishes,
Bill Rudman.
