Two new (to me) animals?

Eye stalks? I assume you are referring to the rhinophores, the two sensory organs that stick up on most sea slugs.

Not 100% sure on this species but nudibranchs eyes are very primitive sensing only light from dark IIRC and are located on the body not on the rhinophores.

Sorry, know absolutely nothing about them... well not true.. I do have a series of images of two Florida regal sea goddesses mating.. not sure exactly what they were doing though...but if rhinophores are what the those things are... ok.

All of the ones I found had their rhinophores retracted (there, I hope I said that correctly).

When you only have one nudibranch where you dive, one does not spend a lot of time learning about them...

Thanks for correcting me.

I am sure there are other species around, they even exist in really cold water around Scotland, but they will be a lot smaller than your examples.
