When I’m out on my swim, one guy I always stop by and say hello to is Old Gnarly, a spotted porcupinefish known here as a swal doodle. He knows when I arrive. The first thing you see are his big luminescent white lips as he floats to the door of his cave. We pause, study each other for a moment, then I give him the thumbs up before continuing my swim. It is a precious moment when you connect with a wild animal like this, and it makes my day.
