In September, we published an article in which Amos Nachoum was derided for letting divers leave
their cage to dive with Great Whites off Guadalupe island in Baja California. Some operators called it
an accident waiting to happen.
As an answer, Amos asked us to publish another piece about his diving with great whites in South
Africa (written by Amos and Angela Schuster, it originally appeared in the Explorers Club Journal – June
2010). We agreed, but we also include a second piece that raises other issues about South Africa great
white diving.

I bring my breathing down to a mere 15
pounds an hour, as my pulse settles in at a
steady 50 beats per minute. Nothing outside
of the present moment lingers in my mind as
I focus on the totality my surroundings. I am
but ten meters down on the seafloor, relaxing
in the relative comfort of a large steel cage.
I am in Shark Alley off the coast of South
Africa, where I have come with two fellow
divers to observe the Great White on its own
terms. The time has come for us to abandon
our protective cocoon.
As I slowly open the gate and exit the cage, I spy a Great White, just to my right, his body scarred by
seasons of spirited mating and encounters with other marine life. He glides through the water in front
of me, barely noticing my presence or that of my fellow diver, who, like myself, is heavily laden with camera
gear.
My motion is fluid, my view is crystal clear, and my heart light as I focus on the shark and its graceful
movements and work to read its complex body language. For the Great White to trust me, I know I
must first trust myself. Any self-doubt or apprehension is sure to compromise the mission ahead. After a
passing glance, the shark comes in for a closer look. His curiosity sated, he moves on to more interesting
targets.
Our view of sharks as hunters of human flesh has been skewed by films such as Jaws. To acquire such
footage, it has been common practice to “chum the waters” with fetid fish remains to attract and then
agitate the sharks into a feeding frenzy. It is exciting to watch, indeed, but a misrepresentation of normal
shark behavior. Contrary to popular perception, humans are not on the menu, our bodies too bony
and devoid of energy-rich fats. Most shark attacks, which average 100 a year—most non-fatal—are the
result of mistaken identity or of test bites, that is a shark’s taking of a small sample to identify an object.
The Great White is gifted with a special “sixth sense”—a network of jelly-filled canals known as the
ampullae of Lorenzini, which are linked to pores concentrated around the shark’s eyes, snout, and
mouth—that enable it to detect electric fields generated by muscle contractions in other creatures and
sense direction through electric fields ignited by ocean currents moving through Earth’s magnetic field.
I first entered the world of the Great White in 1982, while serving as a logistics expert for a National
Geographic shark documentation project undertaken by Rodney Fox; Eugenie Clark, aka the “shark
lady;” and photographer David Doubilet. Since then, I have ventured to South Australia annually to
work with Fox, who in 1963 famously survived an attack from the Great White, which left much of his
abdomen exposed and took 462 stitches to repair. Rather than resenting his attacker, Fox committed
himself to learning all he could about the Great White, pioneering the use of a protective steel dive
cage, which has afforded him hundreds, if not thousands, of hours of shark observation.
I also have had the opportunity to collaborate with legendary underwater filmmakers Al Giddings,
Howard Hall, and Marty Snyderman—all of whom began working with the Great White “outside the
cage.” In 1994, I began exploring the possibilities of diving with Great White in South Africa, working
under the auspices of Shark Research Institute and in cooperation with South Africa’s leading sport fisherman,
Andre Hartman. In time, we began carrying out dives in Shark Alley, located between the islands
of Dyer and Geyser, where much important research has been carried out.
Our work with the Great White is governed by a few simple ground rules. We must have a minimum
of 10 meters of visibility underwater; we operate in the company of a safety diver armed with a yardstick
should a conflict arise; and we retreat from the area if more than two sharks come into view.
Dealing with sharks is all about attitude, not aggression, power, or strength. Diving with Great Whites
require an unusual pairing of heightened awareness of all things around you and a zen calm and control
over your mental and physical state. It is an ultimate expression of living in the moment. From
diving and other experiences in my life—be it carrying out a mission as a military commando, racing
motorcycles, or even falling in love—I have learned that a pounding heart is but an internal alarm that
tells me it’s time to hold on, time to focus, and time get into the moment. For only then can I commit.
Within seconds, I can relax, sensing lightness and a calm as I take comfort in the decisions I have made.
