Is this Chromodoris magnifica?

March 3, 2006
From: Asther M. Lau

Hello Bill!
Found this nudi perching on what seem like a sponge coral or ascidian. Not sure if the nudi is eating it or not because when I found it, it was very still... hardly any movement. Maybe sleeping?

Locality: Mabul Is., 16 metres, Sabah, Malaysia, Celebes Sea, 15 March 2004, Underneath an abandoned oil rig. Scattered rocks & sponges. Muck diving.. Length: 4 cm. Photographer: Asther M. Lau.

Please help me confirm is this is a color variation of Chromodoris magnifica.

Really appreciate it!
Thanx!
Asther

Dear Asther,
This is Chromodoris annae. If you look carefully at the blue part of the volour pattern you will see it is not a uniform colour but has many darker blue specks - which we call a punctate pattern. This is one obvious way that C. annae differs from the very similarly coloured species C. elisabethina. The animal in your photo.is sitting on a large solitary sea squirt.

Unless it is being very adventurous, I sure it won't be eating it. Chromodorids are very specialised sponge feeders.

Best wishes,
Bill Rudman
