Thomas P. Peschak: Swimming With Sharks

A few weeks ago photographer Thomas P. Peschak stopped by the National Geographic offices to show work from his upcoming story on South African marine reserves. Peschak, who studied marine biology, is passionate about conservation, and once we started talking about his work, I could barely get him to stop.

One arresting image from his project is an underwater silhouette of a surfer and a shark swimming side-by-side. Of course I wanted to know: “How the heck did you do that?” The answer, of course, is complex.

“I didn’t want to create an image that conveyed conflict. I wanted to illustrate the reality and the menace that surfers feel—the yin and the yang of the beautiful shapes.”
—Thomas P. Peschak

Peschak knows the ocean intimately, and says he can read shark behavior just as easily as the average person can tell the difference between a poodle wagging its tail and a Rottweiler menacing its teeth. Peschak says it’s the same with sharks.

“They are not dangerous animals,” he says of the blacktip sharks in these photos. “They are powerful, you have to be respectful, and you have to know what you are doing. It comes from putting in the time in the water, watching them, knowing them. If you don’t know what you are doing, that’s when you get into trouble.”

A blacktip shark inspects a surfer paddling on a prototype surfboard fitted with a electronic shark deterrent built into its underside. The electronic shield was switched off during the test and the sharks approached closely. When a shark swims into an electrical field, it is thought its 'ampullae of Lorenzini'—organs that detect weak electromagnetic fields—are overstimulated, causing uncomfortable muscles spasms.

In these photos, surfers test a prototype of a shark-resistant surfboard under baited conditions off the KwaZulu-Natal coast in South Africa. A device in the board sends out an electromagnetic field to bother the sharks and keep them away. While not yet in mass production, Peschak says the concept shows that people are thinking beyond killing sharks—and instead are looking for ways to co-exist.

Perhaps one of the most surprising things about Peschak’s method is that he doesn’t use any SCUBA gear—instead, he free-dives with only a mask, snorkel, fins, and a weight belt—holding his breath for a few minutes at a time. He says it gives him greater mobility in the water, and allows him to work for longer periods of time. It also makes him seem less threatening to the wildlife.

Peschak also pre-visualize images before he dives, sometimes even sketching them out in advance so he knows what to shoot once he’s in the water.

“One of the things people forget is the amount of time and research that goes into taking pictures,” says Peschak. “Once you are in the water it’s just waiting for it to happen. You know it’s going to happen because you’ve done your homework. One of the secrets is curiosity—speak to people, become a sponge, and make smart decisions about where and what to photograph.”

Thomas P. Peschak’s book Sharks and People was published by the University of Chicago Press in August. You can also see more of his work on his website.

    Not only are the visuals stunning and inspiring, but the reasoning behind them, gives me a sense of understanding and the ability to applaud you as a photographer and fellow human. What a great view point you have. Looking forward to seeing more, NG should give the option to ‘follow’ certain photographers. Can you?

    The only thing worse than a hungry Tiger Shark, Surfboard and Surfer is a very hungry Tiger Shark, Boogy Board and Boogy Boarder …

    I am a surfer in Volusia County Florida.they call this the shark bite capital of the world.I am also a surfer and I coexist with the sharks as well as my fellow surfers. swimming and or surfing in an area where sharks are obviously feeding is not a good idea.birds over the water bait fish in the area all big signs.I have been bitten once by a 3-foot Sand Shark.we swam together in a wave and accidentally bumped into each other that’s the only reason it bit me, an accident.beautiful photos thank you for sharing sometimes you just have to let Mother Nature be Mother Nature and just enjoy her beauty.

    I love it. Anything that shows people that sharks aren’t mindless eating animals is key in my book. The shot from below is outstanding. Great work.

    Anything that protects surfers (even by a percentage) and keeps sharks from hurting them will help protect sharks. I think those taking part in the baited trial are v brave. You wouldn’t get me doing it!

    Building knowledge about sharks is important. I love nature photography and appreciate everything that goes into it. But to suggest blacktip sharks aren’t dangerous is naïve at best an irresponsible at worst. Ask Steve Irwin’s widow if sting rays are dangerous. Ask the shark “expert” who kissed a “harmless” nurse shark and almost lost his mouth. (It’s on YouTube.) We need to protect nature but never lose respect for it.

    Beautiful images and important to gather information on these amazing creatures for both their and our future benefit. However, I do agree that wild animals are wild and it is a tad fool hardy to suggest they are not dangerous just misunderstood. The recent doc re “trained” orca whales and their murderous behaviour to their keepers, albeit in captivity reminds me that any human contact with wild animals is an imposition for them unless you intend to let them eat you or you’re conducting some activity that warrants contact for the sake of their “best interests”.

    I disagree with his comment about sharks not being dangerous. All animals are dangerous. One of my cats will shred your skin if you touch him in the wrong spot!!! Wild animals are especially dangerous. It is my belief that when a person starts to think a wild animal is not dangerous or that they can “read” an animals body language that they get hurt. Look at all the animal experts that have been killed by the animals they thought were their “friends”. Do I respect him? Yes. Do I appreciate his efforts for conservation and methods for studying them? Absolutely!!! Am I afraid for his safety? You bet I am!!!

    Courageous outstanding people who do this sort of work, we all enjoy their work so much, I know. I do, anything from the underwater world is so fascinating, keep up the good work for all the world to see.

    Inspiring. We’ve just had two fatal attacks in Australia and now the West Australian Government is talking about culling sharks there. A lot are great whites. A sad, knee-jerk reaction. Must we humans rule everything with blind force?

    I have personally met someone who was a commando. Commandos in the British army where trained to swim with sharks in world war 2.
    He told me if he was attacked by a shark he was told to stab it in the eye.
