Concerning message #22261:

Hi Bill and everyone!
I find it hard to believe this could be Risbecia pulchella. It looks more like Risbecia tryoni. The fact sheet photos look like Risbecia godeffroyana, both of which are found here in sthn Queensland. Risbecia pulchella dosen't have black spots with lighter areas around them like Risbecia tryoni.
Hummmm
Cheers,
Gary

Dear Gary,

I'm glad someone has their wits about them! While Marcel's message [#22261] was referring to Valda Fraser's message [#22255], which was of R. pulchella, the animal in Marcel's was indeed the purple-spotted R. tryoni rather than the yellow-spotted R. pulchella. My brain must have been in sleep mode when I answered that message. Interestingly Marcel's message suggests that the 'cuddling' behaviour may, like trailing, be a generic characteristic - and perhaps an attraction to that type of sponge is as well?

Best wishes,
Bill Rudman
