Concerning message #22122:

Hi Bill and everyone!
Here is a record of Glossodoris hikuerensis from our area. We have found this species up to 110 mm in length. It gives off a milky white substance at the slightest bit of disturbance. I have included a photo of it eating, maybe you can tell what the food source is.

Locality: Mooloolaba, Sunshine Coast, 17 m, Queensland, Australia, Pacific Ocean, 15 June 2009, Subtidal. Length: 110 mm. Photographer: Gary Cobb and David Mullins.

Cheers

Dear Gary,

Thanks for the record - and the tantalising photos of it apparently feeding. Unfortunately the sponge is too well hidden to give us even a hint at its identity. We don't know much about the sponge or sponges it feeds on. The only clues suggest it is a thorectid. The milky-white substance it exudes when disturbed is almost certainly a deterrent secretion manufactured from chemicals it ingests from its food sponge.

Best wishes,
Bill Rudman
