hey Edy, it's nice to see a nudibranch looking so "natural" with just natural light. where did you take the photo, and did you use natural light only on purpose?

Thank's Scott,but your photos is much better than mine hehe...
I took the photo at around my place when I dive with my guest.

Yes I just used natural light because I don't have enough money to buy Strobe hehe...

Hi Edy, please let us know where you took your foto. Do you know the ID of your nice slug? Am thinking it might be a species of Halgerda, based on the dorsum color/texture, though the the branchial plume sure resembles a Taring halgerda.

Hard to ID this Halgerda without being able to see the coloration between the yellow spots. It is either, H. carlsoni or H. batangas.

Hi Edy, Dave and I believe your nudibranch is a Halgerda. Dave thinks it's either a H. carlsoni or H. batangas. Based on the distribution of these two slugs, since you photographed yours in Indonesia, I'm strongly inclined toward Halgerda batangas. Remember that the color spectrum diminishes rapidly in water, with the warm colors (yellow, orange & reds) getting absorbed and disappearing first. That's why we tend to see only blues & purples (cooler colors) the deeper we go where ambient light gets weaker, as in your photograph. Thus the yellow dots on your Halgerda would actually be a hue of orange/reddish orange. Here's a photo of a H. batangas, with strobe light illuminating the dorsum.

BTW, both H. carlsoni and H. batangas are on pages 180 and 181, respectively, in the book "Indo-Pacific Nudibranchs and Sea Slugs", by Gosliner, Behrens and Valdes.

Cheers, K;-)
