Info Please help to identify this creature

[Ukmc]

It is about 5 cm. Caribbean.
I suspect Elysia genus, but distinct from a lettuce leaf slug.

Thank you in advance.

Some kind of flatworm.

This one has two rhinophores - you can see on the left. I don’t think it is a flat worm. I think it will be a some type of a sea slug.

I don't see any rhinophores. Can you zoom in on them?

Thanks for zooming in. I have never seen such rhinophores before. They look like a scroll-tube sheet soft-coral that the flatworm ran over.

Lettuce Sea Slug has a very similar pair of rhinophores and also a corrugated frame, thus, was my supposition of this guy being related. Hopefully, someone has seen it and will be able to identify the species.

They do look like Lettuce Sea Slug's rhinophores.

Looks like an Elysia Crispata ( Lettuce Leaf Sea Slug) all decked out for Halloween. Striking coloration on topside, Although the underside appears to be pretty much the same. Have seen different colorations from Bay Islands to Cayman Islands.
Where did you find this beauty ?

Send the picture over to Mickey Charteris at CocoVIew Resort, if anyone would know what it is he would be the person.
