Concerning message #9626:
Hi Bill,
The bright orange of the eggs attracted my attention to this large Umbraculum umbraculum laying eggs. It was completely encircled with its own eggs. We know we have already sent in some egg laying shots but thought this might still be of interest.
Locality: The Pipeline, Nelson Bay, Port Stephens , 10metres, New South Wales, Australia, Pacific Ocean, 09 January 2009 , Sandy bottom sponges, bryozoans, soft corals, hydroids and ascidians. Length: 160 mm. Photographer: Leanne and David Atkinson.
Regards,
Leanne & David Atkinson

Photos of animals 'doing things' are always welcome, and it especially valuable to get another photo of Umbraculum egg-laying. As you imply from your message, the bright colour of the egg certainly draws attention to the animal. What is just as remarkable is just how camouflaged in colour and texture the animal is on what is apparently its food sponge. The growths covering the shell complete the illusion that Umbraculum is just part of a sponge colony.
Best wishes,
Bill Rudman
