Dear Bill,

I took this photo of mating nudis in the Russell Islands in Solomon Islands. They were hanging upside down on a wall at about 18 metres.

We are uncertain as to whether these are Nembrotha lineolata or Nembrotha rutilans. Could you please assist in identifying them?

Nembrotha lineolata - finding mating partners?

July 13, 2007

From: Carlos R. Munda

Here are a couple of mating nembrothas (N. lineolata?). I first observed the specimen in the middle photo about a foot from the other one. I first noticed the strange protrusion on its side and wondered if it was some kind of injury.

When it had worked its way to the other nembrotha, I noticed the same appendage starting to grow from the second specimen and thats when i figured what was about to happen...

What i can't figure out is how the first specimen knew that other one was there. I figure the way the current was moving had something to do with it. but if that was the case, how did the second Nembrotha know when to stick its own organ out just when its mate was getting near - but not yet near enough to touch.

Hi Bill

After having browsed through all your colour varations of Nembrotha lineolata I'm pretty sure that the attached photo shows one as well.

However, the photo was taken in the south of Tanzania so perhaps distribution could be expanded a bit (if you agree to the id, of course)?

Re: Nembrotha lineolata with transverse lines

From: David Bush

Bill,

Concerning my earlier message [#14060]. I contacted the liveaboard company (Mike Ball Dive Expeditions based in Cairns). They gave me the following coordinates for "Two Up" reef:

Coral Sea, Flinders Reef, Lat: 17 41 471, Long: 148 30 479

It is basically two large Bommies sitting next to each other, thus the name. It is a common site for the Spoilsport (dive boat), so if you want more details, you could contact MBDE. I'm sending along two more pictures.

Thanks for you help, let me know if you learn anything more about this variety...

Hello,

I found this Nudibranch and so far haven't been able to find anything identifying it. Thought perhaps it might be new. It is very similar to the "Lined Nembrotha" with the exception that the lines run transverse to it's body rather than parallel. Let me know if possible.

Hi Bill,

Here are two views of Nembrotha lineolata laying eggs. Do you think it is significant that this ascidian-eating slug has chosen to deposit it's eggs on the solitary tunicate, Polycarpa aurata? In the side view I can see how the foot plays a role in pressing the egg ribbon onto the substrate. Divesite: Batu Sandar, Lembeh Strait, Sulawesi, Indonesia
