Phyllidia coelestis? from Borneo

Concerning message #7255:

Hello Bill,

Can you please assist in identifying this nudi? I'm not quite sure if this is a Phyllidia coelestis or a juvenile Phyllidia varicosa.

Attached are two images, which one of them shows an egg ring next to the nudi. I've a feeling it's just coincident that this nudi is next to this ring of eggs. Don't thing the eggs belong to this nudi. But maybe you'll find it useful information.

Locality: Sipadan Island, Sabah, Malaysia, Celebes Sea. Depth: 18 metres. Length: 1.5 cm. March 13, 2004. Wall of Coral Reef. Photographer: Asther Lau

Dear Asther,

It is still not easy to distinguish some species of Phyllidia clearly, and this is especially true of juveniles. I would suspect this may be a juvenile of Phyllidia ocellata or perhaps  Phyllidia exquisita but I'm afraid I can't be positive.

I can't say anything about the egg ribbon other than that it definitely was not produced by the small phyllidiid, and it certainly didn't hatch from the ribbon.

Best wishes,
Bill Rudman
