Tap, tap, tap! Our dive guide was rapping on his tank with such enthusiasm that I knew he had found something truly special. I had been searching in the muck for over an hour in hopes of finding octopus, but so far, had come up empty. As I swam over to where he was hovering, you could see the broad smile on his face as he pointed to his slate.
I had never seen a blue-ringed octopus before, and as I tried to control my excitement and ready my camera, the guide pointed with his reef stick at a lump in the sand.
