Underwater astonishments

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. This short talk celebrates the pioneering work of ocean explorers like Edith Widder and Roger Hanlon.

Most of our ocean remains unexplored, yet even brief dives reveal dazzling displays of bioluminescence and animal ingenuity. Creatures like cephalopods can become invisible in plain sight, shifting color and texture to blend perfectly with their surroundings. In the pitch-black depths, life is more diverse and dense than in tropical rainforests. These discoveries remind us how little we understand about the planet’s largest environment.
