I don't think so Lyndon. Those J. cristatus images you link to on nudipixel are all in the Atlantic & Mediterranean...
I took a quick tour through the rest of the nudipixel images for the genus, didn't see a match.
It could very well be an as yet undescribed species.
Did you also take a look on these sea slug forums?
