Never put your camera away early. Another rule I follow. As we were headed home to shore, I looked in one more hole. There was a brightly colored crab. One shot only, and the exposure and focus were kind. There’s no name in the guidebook. I chased to get one more shot. The other side of the hole had two spiny urchins guarding. I could glimpse the crab, but no shot, no way. I’ve been spiked by an urchin. Once was more than enough. The crab was very shy and never put in a new appearance.
