Chromodoris cf. colemani? from Sulawesi

April 2, 2007
From: Sebastian Ferse

Dear Bill,

I found these two slugs on a night dive, on a rubble patch below a large staghorn coral colony, the rubble being overgrown by coralline and fleshy algae. I think these might be Chromodoris cf. colemani, but they lack the narrow white band along the mantle margin.

Locality: Lihage Island, southern slope, 10 m, North Sulawesi, Indonesia, Pacific Ocean, 30 March 2007, rubble area on upper reef slope. Length: 3.5 cm. Photographer: Sebastian Ferse.

Dear Sebastian,
This is what I am calling Chromodoris cf strigata, but from its general shape, it may be a species of Hypselodoris. We won't know until its anatomy is looked at. These are both very tantalising photos as they both show two animals apparently feeding or investigating something very intently, but I have examined your high resolution scans carefully and can find no identifiable sign of food.

Best wishes,
Bill Rudman
