Naturalist E.O. Wilson once wrote that “a lifetime can be spent in a Magellanic voyage around the trunk of a single tree.” Easy for him to say: He’s made a distinguished career out of studying ants and a lot of other little wriggly things that most of us dread finding in the shower in the morning.
But Wilson found a kindred spirit in photographer David Liittschwager. Liittschwager has spent years photographing animals, from squirrels to beetles, in a Darwinian effort to wrap his mind around the sheer variety of life on the planet.

There may be as many as 40 million species we don’t even know about — and that doesn’t even take into account the really little things,” Liittschwager says. “How do we get our heads around that? We need a manageable sample size.”
So Liittschwager created the One Cubic Foot project, which involves dragging a small, green, open-sided box around the globe and setting it up in different places to see what wanders, slithers, swims, or flutters through. A batch of the resulting photographs was published in National Geographic last year, along with an essay by E.O. Wilson.
Now Liittschwager has gone big with this small idea, producing a series of supersized photos of creatures he snagged in a 12-by-12-inch net dipped into the water under the Golden Gate Bridge. The images went on display this week at the David Brower Center, a hub for eco-minded nonprofits in Berkeley.

His catch varied widely with the tides and the time of day, he says. “It’s a whole different group of creatures at night.” Based on the number of creatures he netted, he estimates that up to 2.6 billion creatures might move through a single cubic foot of bay water in a single 24-hour period.
For this project, Liittschwager stuck to creatures visible to the naked eye, but says his next mission may be to look at the “really little things” — requiring a microscope. For that, a cubic foot will be too big a sample size; a cubic inch might be more like it. Or maybe he’ll be a little less scientific this time around: “The handful of soil is sort of famous for being the Holy Grail for biodiversity.”
When he’s done, you’ll never look at your garden the same again.
One Cubic Foot: Miniature Surveys in Biodiversity is on display now through the end of January.
