Dear Chay Hoon,

Thanks very much for this photo. With its position as a 'basal' chromodorid it would be good to have a clear idea of what this species feeds on as we now know that food specificity in the family is closely linked to their evolutionary relationships. Our evidence on the food choice of Cadlinella is not that good for this species, so any additional records are very welcome. The sponge in your photo looks like a species of Darwinella forming a very thin layer over the substrate, but I will need to have that confirmed by a sponge expert

Best wishes,
Bill Rudman
