Concerning message #16350:

Hi Bill,
Have been reading Nerida`s message (#16356) about this brown form of G. averni being similar to Glossodoris sp.3. I didn`t come across these animals when I was doing my searches. Maybe that was just as well, as it would have confused me even further.

I have included another 3 photos of the brown form of G. averni for your records.

Upper right: Manta Bommie, 17th December 2005, Depth 11 m, Temp 25 deg c. Middle left: Manta Bommie, 30th December 2005, Depth 12 m, Temp 26 deg c. Middle right, Lower right: Manta Bommie Point Lookout North Stradbroke Island, 12 metres, Queensland Australia, Pacific ocean, 4th December 2005, rocky reef with sponges, hard & soft corals . Length: 40 mm. Photographer: Bruce Wilkie.

Many Thanks,
Bruce Wilkie.

Dear Bruce,
The more [photos] the merrier ! At present I'll keep them all on the G. averni page so I don't lose them again but it doesn't mean I have no doubts about their identity.

One interesting thing in these three photos is that I can see a potential food sponge in the two middle photos [see closeup photo alongside]. If you could check through your photos and see if this sponge appears in any of your other photos I would be grateful. It's a sponge which often is overgrown so it's possibly present in your earlier shots but effectively invisible. It would be nice to know what it ate, even if we are not sure what it is.

Best wishes,
Bill Rudman
