Thats the thing, there are sea slugs that look like nudibranchs but they are not nudibranchs

Looks similar to the slugs I found a few years ago, these were id’d as Sarcoglassans. Very cool shrek looking fellas, they eat algae or can use their flaps like a solar panel.

"Sea slug" is the common name for nudibranch.
Yours looks greenish - if so, it's not a berghia.
