Kicking slowly through a great blue void, to deep to see the surface, and hundreds of feet above the ocean floor, I allow the current to carry me so that I can conserve the priceless breath of air I'm holding in. I can hear a pod of spinner dolphin approaching, though I can’t see them yet. First a few flashes of light off of the sides of tuna, then the torpedo shaped fish begin to dash by on all sides. Following close behind, five hundred porpoise effortlessly glide by in formation. Some circle just beyond arms reach and others herd the young away from me. As quickly as the ocean revealed them, they are gone, their whistles still audible.
