Can you identify these slugs?

I was out filming at Junkyard Reef on Koh Tao and saw these huge slugs.

None of us had seen anything quite like them before....can anyone identify them?

Apparently they are Sea Hares ......

Yes, they are sea hares. The image quality isn't good enough to stop the video and get a good look at their markings to identify them more definitively, but I think they may very well be Aplysia juliana.
