Diane, of course, found this amazing nudibranch (~5mm). Truly, the only way to see it, to distinguish it from anything around it, was when it moved. It displayed a rocking motion and it's little 'lateral flaps' waved to and fro. There are actually two of them in the second photo, but the individuals are difficult to discern even in the photographs. We'll have to send this on for identification because we've seen nothing like it in our reference books.
