nudibranch red sea

I came across this little guy on a night dive last week in the Southern Red Sea. Couldn't find him in any of the books. He was only about a 2cm or so long, so could be a juvenile that will change colors into something more recognizable later, but not sure.

Anyone got any ideas?

It looks more like a flatworm - possibly unidentified.

I can't find it in any of my reference books. It may be worth sending to Bernard Picton who is the Curator of marine invertebrates at National Museums of Northern Ireland - bernard.picton@nmni.com

Found a similar one here in Malaysia few weeks back.

But the color is different.

My bet, it is a flatworm.

Yes, it's a flatworm. Nudibranch books will not be helpful.

It appears to be this one:

That one looks kind of close scubamarli, but not quite sure.

Got an email back from Bernard Picton, and he also has no idea what kind of flatworm it is.

Yes, it is certainly a flatworm, but I’ve no idea what species it is, I can’t find it on any website. These Polyclad flatworms often mimic nudibranchs. Many of them don’t have names yet.

That's pretty much what I expected. My guess is that there are as many undescribed species of flatworms as there are described ones --- maybe more.
