Chromodoris geometrica feeding

December 4, 1998
From: Akos Lumnitzer

Dear Bill,

I photographed this slug at La Perouse, at the entrance of Botany Bay, Sydney. I first saw it in late October 1998, 7 meters, on this sponge. It stayed on the sponge for two consecutive dives.

Dear Akos,
This is another tropical species making a rare visit as far south as Sydney. it is interesting to have a photo of it on a food sponge. The sponge is almost certainly a dendroceratid, which are characterised by the loss or great reduction in skeletal spicules. The small bluish slug in the background, on the same sponge looks like Chromodoris thompsoni which is known to feed on Chelonaplysilla violacea, another purplish dendroceratid sponge with a much more encrusting growth form...
