Roboastra luteolineata

(Baba, 1936)

Jun V Lao thought nembrotha.. but not listed, or might hav missed, 1 inch, 37m, nusa dua

Arne Kuilman Tambja sp.?

Suzan Meldonian wow that is really gorgeous!

Marli Wakeling Roboastra luteolineata.

Arne Kuilman Maybe a little too much green in the overall photo?

Mike Bartick I was going to say Robostra, but I see Marli beat me to it...so I'll just add, nice composition...judging by the background and lack of ambient light, I would also add the greens look accurate..

Christopher Thorn What kind of Nembrotha species could this be? 18 m, 40 mm. Taiwan, South Bay.

Roy Arthur David Lontoh Looks like Roboastra luteolineata to me

Christopher Thorn Oh yes, looks a good match, cheers:-)

Lucas CerCur Yes, R. luteolineata.

Harald Schottner

Arantxa Di Mare Tambja or Roboastra??.

Roy Arthur David Lontoh I think Roboastra :)

Maurice Hein Could somebody help me identify this nudibranch found in the Maldives?

Andrew Trevor-Jones Could it be Roboastra luteolineata?

Frank Wehner looks like a kind of Roboastra...

Frank Wehner @ Andrew - its ground color is not black...

Evie Go luteolineata is black body w/ bright orange lines & has dark green colored rhinopores...

Gary Cobb From what I can see this is Tambja affinis (Eliot, 1904)

Patrik Good Interesting link: Rudman, W.B., 1999 (Apr 23). Comment on Tambja affinis v. Roboastra luteolineata by Ross Armstrong. [Message in] Sea Slug Forum. Australian Museum, Sydney. Available from http://www.seaslugforum.net/find/799

Gary Cobb The reason I think this photo is Tambja affinis is solely because of the 'outlined' green longitudinal lines. The only real way to determine the species is by way of microscope. Roboastra luteolineata is a common species here on the Sunshine Coast and I have never seen 'outlined' longitudinal lines. The other thing is what appears too be a yellow foot. Surely not Roboastra luteolineata.

Gary Cobb ID is easier if the whole animal is showing. In this photo we can't see the head or oral tentacles or rhinophores.

Frank Wehner @ Gary - Agree with you.

Gary Cobb Plus T. affinis is typically an Indian Ocean species.

Gary Cobb Just a tip for everyone...when taking photos of nudibranchs always try to get as much detail of the animal as you can...try to shoot different angles, get closeups, move the animal to get the most information about it. >>>that is if you intend on getting id identified!<<<

Maurice Hein Let me check if i have anything from the front. Unfortunately i couldn't get around to get a frontal shot due to strong current and obstructions on the other side.
