Phyllodesmium briareum from Malaysia

From: Ho Wei Kwok Alvin

Hi Bill,

Need your expertise again. Was taking pictures of a Pteraeolidia ianthina when I noticed another nudibranch beside it. I'm not too sure which species is this exactly though i'm quite sure it is a Phyllodesimium.

Locality: Turtle House, Pulau Lang, West Malaysia, South China Sea. Depth: 10-15 m. Length: 10-20 mm. 01 October 2005. Sandy bottom, Coral outcrops. Photographer: Alvin Ho

Thanks and regards,
Alvin

Dear Alvin,
Yes ot is a Phyllodesmium. It is Phyllodesmium briareum, which is almost certainly one of the solar-powered species. The lines of brown patches you can see on the cerata are little clumps of the unicellular zooxanthellae it keeps alive in its body.
Best wishes,
Bill Rudman
