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.

A pioneer in ocean exploration, David Gallo is an enthusiastic ambassador between the sea and those of us on dry land. He explains that “today we’ve only explored about 3 percent of what’s out there in the ocean. Already we’ve found the world’s highest mountains, the world’s deepest valleys, underwater lakes, underwater waterfalls … . There’s still 97 percent, and either that 97 percent is empty or just full of surprises.”

David Gallo works to push the bounds of oceanic discovery. Active in undersea exploration (sometimes in partnership with legendary Titanic-hunter Robert Ballard), he was one of the first oceanographers to use a combination of manned submersibles and robots to map the ocean world with unprecedented clarity and detail.
