I'd like to identify what it was that twice flicked or shocked me while snorkeling in Culebra, a small island off the coast of Puerto Rico. I believe in hands-off diving and snorkeling, but nonetheless there were some times where I had to pinch a portion of (coral-covered?) mossy, greenish rock or place a bare foot against it for support in a current while trying to photograph a small creature/etc. In the waters of two different beaches, something in the coral (or rock/moss) made a loud snapping sound and gave me what felt like a hard flick or electric-bug-zapper shock. The first time it happened was on the bottom side of my heel, and the second time, a day or two later, was on my pointer finger. It didn't cause any injury, but it did hurt a little. I have attached a screen shot of a photo I took, to give an idea of the environment.
