On a night dive in Bunga, I caught a slight movelment in a small yellowish blob next to a brain coral; thinking it was a crab, I took a couple of pictures, with Kitty providing focussing aid with her torch. Then we hurried on to catch up with the rest of the dive group. A day later, when examining the photos in the camera, I discovered what it was. Our first blue-ring octopus (~3cm) and we didn't even know what we're looking at.
