Shark Diving with Great White Sharks

Arrival to Guadalupe
is always exciting for our divers and crew. Divers wake up after a 20-hour crossing from San Diego, California and walk to the bow of our vessel with coffee in hand investigating and filming the islands ancient tangle of volcanic formations, cinder cones and Devils Post Piles while we set up for our three-day stay here.

Many of our divers say they half expect to see some kind of flying dinosaur swoop down from the high 3000-foot craggy peaks after our arrival. Guadalupe is that kind of wild "off the beaten track" kind of place, 210 miles from nowhere located in deep blue waters of the Pacific. The perfect place for world-class tuna fishing and as it turns out unparalleled white shark diving.

Our first encounter with a 14-foot male white shark complete with "shredded" dorsal fin and several deep bite marks on his head happened at 7.00am.

He came in fast from the left, our first sight was of his mangled dorsal fin slicing through the surface toward our hang baits (tuna), he hit the first one with an unexpected fury, then turned and zeroed in on the second hang bait missing it and disappearing into the blue distance.

Closer inspection of this deeply scarred shark revealed his entire left eye was milky; it had been damaged in the encounter with a larger more aggressive shark in years past.

These impressive wounds should have killed this animal, apex predators can sustain a lot of physical damage as we discovered later in the season with Chompers, Top Notch and Split Fin not to mention Maximus who was missing clearly one third of his tail to a very recent bite.

Another smaller 10-foot female we named Cuddles soon joined us along with two unidentified males. Her disposition was perfect for shark diving. Slow moving, cautious, and inquisitive at the same time. She had an unusually large and distended belly, looking like she had fed very well recently. Shredder on the other hand was quirky, fast moving and very aggressive, attacking hang baits (tuna) with abandon and flashing past our 20-foot shark cages at top speed thrilling our divers. Even in 100-foot visibility a white shark can sneak up on divers they will not even know it is there until it's right on top of them. Fortunately we have 100 square feet of cages between our divers and these animals, even so having a shark like Shredder with his scarred face and milky eye run his pectoral fins along the cage bars like a school kid on the neighbors fence is a bit unnerving even to the most dedicated shark diver.

Over the course of the three days we spent at Guadalupe our divers filmed and dove with over 14 different Great Whites. It was Shredder who stole the show. His arrivals on site were always quick, coming in fast from either the left or right and staying just long enough to destroy one or two hang baits in a powerful display of predation. This was also one of the few sharks we encountered that seemed to be "aware" of the divers in our cages, spending time to investigate them with his good eye on several extremely close passes.

Shredder Takes a Bite
I was up in the wheelhouse with our boats captain (Scotty) during the last dive of our last day at the island. This had been an amazing expedition thus far and our shark cages were loaded for the last time with die-hard shark divers. At the time three new sharks in the 10-13 foot class were entertaining them. Two divers not in cage rotation, Kevin and Matt, were fishing for "last chance" tuna on the bow of our 86-foot dive boat the Ocean Odyssey when our crew in the wheelhouse heard a large splash.

Seconds later a startled voice called up to us, "Umm, hey, a shark just blasted up and severed the anchor cable from our boat", that was Matt, one look into his face I knew he was speaking the truth. Our ships captain was not so sure, saying "that's a rated 20,000 pound poly-pro anchor cable, there's no way a shark just bit through it". One of the ships crew was summoned forward to have a look and sure enough came up with the last 5 feet of cable ending in one very messy shredded fray.

A 14 foot Great White shark had just leapt up almost 10 feet clear out of the water and bit through our anchor cable, about the size of a mans wrist and designed to hold an 86 foot dive boat in place in even the roughest weather conditions!

We were now adrift with shark cages fully deployed, sharks in the water and one shark (Shredder) with a new taste for anchor cables. In the history of shark diving I doubt this has ever happened to another dive boat. Crew raced forward and aft, we had our shark divers calmly exit the cages (30 minutes early) pulling them from the water in record time. In exactly 20 minutes we had the ship squared away and ready to get under power. Once we had settled down our divers were thrilled. After all you cannot call it an "Absolute Adventure" until a shark chews through your anchor cable!

The Theory
It is rare for Great Whites to randomly attack objects that are unusual or strange to them, although there's data from the Farallon Islands in San Francisco showing attacks on objects floating out there. The difference is the Farallons is well known for extremely poor visibility, in fact 20 foot of vis is considered by many a great day out there.

White sharks are primarily visual predators so it is not surprising to see data coming from the Farallons of sharks in poor vis attacking an object that kind of resembled a prey item. In this case we believe that Shredder (due to the damage in his left eye) just has to "try harder" to survive, it is a form of apex predator adaptability. With a handicap like a missing eye this animal has to attack far more objects in his quest for food sources just to stay alive. Our anchor cable being white in color and as round as a mans wrist might have seemed like an intestine from a dead whale or some other food source. Either way his attack mode was both spectacular and devastating, unfortunately none of our crew got to witness it first hand it must have been simply amazing to witness in person (Matt forgot his camera!).

Great White sharks at Isla Guadalupe never cease to amaze and thrill our divers and our crew alike. This is truly the last great outpost for this apex predator and we are fortunate to be able to explore their world for three short months each year surrounded by and island and shark diving conditions that are the envy of the world. We'll continue expeditions again next season 2004 with 10 planned weeklong expeditions and a brand new "anchor chain". Every day we learn more about these magnificent animals, fortunately for us there's only one "Shredder" at Isla Guadalupe.

Patric Douglas is the CEO or "Chief Excitement Officer" with Absolute Adventures-Shark Diver www.sharkdiver.com . Along with Roger Moore and the crew of the Ocean Odyssey they will be returning to Isla Guadalupe to introduce divers to great white sharks, sample DNA furthering the understanding of this unique apex predator.
