Also the image is photoshoped you can tell because the artist changed the opacity in the slug layer and forgot to clean up some of the algae strands showing through the slug. ( GOOD CALL PAUL) look at me rhyming!
I wonder how elysia chlorotica is different from elysia crispata which is the green lettuce nudibranch, which isn't a true nudibranch. Both use cholorphyll and chloroplasts to make food. Is the difference that chlorotica actually produces it's own and lettuces have to harvest theirs?
It might have been touched up for media purposes but its definitely real. It's also not a new discovery. Search "Elysia chlorotica" It's just been recently released...
That photo looks different than the other ones on the sea slug sites to me. The one in the link looks like a monti cap attached to it. The other pics just say that the digestive gland scan be seen through the skin so they have a green appearance. I had no idea they were the same one.
