Night dive on Kona, Hawaii with feeding manta rays. A dozen or more dive lights are set up on the bottom facing the surface to draw in the plankton which in turn draws in the mantas. At the one minute mark in the video watch for a large moray eel swimming up through the light column among the fish and mantas. The eel was actually hunting the fish crowded at the top of the light column.
