Interesting Tunicate. The directional arrows are a nice feature, much better than having to write instructions all over it in several languages for proper reef placement.
Great shot of the nudi threesome. Really nice lighting and detail. I think Peter's GF is just jealous.
I think I've worked it out. Squinting hard I can make out a tailfin and what I took for rhinophores on the nudi are actually dorsal fins.
Given the number of photographs I've taken of this very subject, I can't believe I didn't recognise a fish butt.
