We saw two of these on the 2017 trip, both figured below. The first photo shows an individual found on a night dive at Saimsim and the two photos below that show another one on the slope at Manit (Secret Bay).
The one below was at Basura in May 2016. It was unusual with its narrow, pointed dorsal pustules, much like an individual from Bali (last two photos on linked page).
