David Gallo shows jaw-dropping footage of amazing sea creatures, including a color-shifting cuttlefish, a perfectly camouflaged octopus, and a Times Square’s worth of neon light displays from fish who live in the blackest depths of the ocean.

A pioneer in ocean exploration, David Gallo is an enthusiastic ambassador between the sea and those of us on dry land.
