Sea Butterfly which could easily be a movie poster!
Clione limacina, common name Naked Sea Butterfly, Sea Angel, and Common Clione, is a sea angel found from the surface to greater than 500 m in depth.
It lives in the Arctic Ocean and cold regions of the North Pacific and North Atlantic Oceans. It was first described by Martens in 1676 and became the first gymnosomatous (without a shell) “pteropod” to be described.

When you’re given an image like this, it’s truly irresistible to Photoshop.
