Chromodoris sp from Philippines

Dear Bill

Is it possible that this nudibranch is a color variation of Chromodoris magnifica?

The orange band is marginal and not submarginal like in C. magnifica.

Locality: Sindigan wall, Sabag, 25m, North Mindoro, Philippines, South China Sea, April 2007. Length: 6cm. Photographer: Sylvain Le Bris.

Dear Sylvain,
No this isn't C. magnifica. There are still a few puzzles amongst the black-lined chomodorids and I think this is one I am calling Chromodoris cf. africana. I can't even be sure all the animals I have put on this pages are the same but I find it a useful start to try putting 'look-alikes' together. Normally I do this privately and make many changes before I come up with a workable hypothesis which is worth testing, but the Forum forces me to make my mistakes very publicly. So just remember not everything I say may stand the test of time - or the test of more evidence.

What is quite interesting in your photo is the bright red sponge your chromodorid has its head on. Have you any more photos of this animal which may show the sponge in greater detail - or may show the chromodorid feeding perhaps?

Best wishes,
Bill Rudman
