Concerning message #17129:

Hi Bill
Last saturday, 3rd March, I was diving the wreck of St Paul, north of Moreton Island and found 4 Ceratosoma amoena. Unfortunately couldn't take photos as my camera is on the fritz. This wreck is 42 m deep, water temp on the bottom was 25C. I was using trimix, so am confident of my identification :-) It seems that this creature would be bucking the trend and heading north rather than the usual tropical finds in temperate zones. I have previously seen it at "China Wall" which is on the eastern side of Moreton island, north of the Rocks at Stradbroke island.

Locality: Wreck of the St Paul, 42 m, QLD, Australia, Pacific Ocean, 03 Mar 2007, wreck on sandy bottom. Length: ~2 cm

regards
Rachel

Dear Rachel,
It is certainly interesting to find this species so far north, but Willan & Coleman, (1984) reported it from Nth Stradbroke Island, so its presence in southern Queensland is probably not a recent event. When you camera is back in action it would be good to get a photo or two of your population just to see what the colour pattern is so far north. And of course if you find it feeding it laying eggs that would be worth a few photos as well.
Best wishes,
Bill Rudman
