With vibrant video clips captured by submarines, David Gallo takes us to some of Earth's darkest, most violent, toxic and beautiful habitats, the valleys and volcanic ridges of the oceans' depths, where life is bizarre, resilient and shockingly abundant.

In the deepest, darkest parts of the oceans are ecosystems with more diversity than a tropical rainforest. Taking us on a voyage into the ocean -- from the deepest trenches to the remains of Titanic -- marine biologist David Gallo explores the wonder and beauty of marine life.

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.

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

Explore endless waters with these captivating talks that shine some (literal) light on what’s going in the deepest, darkest parts of our oceans.
