...territorial, and so chances of catching the culprit at an attack site are minimal. Dr. Kim Holland of the Hawaii Institute of Marine Biology at the University of Hawaii has been monitoring tiger movements with the CHAT (Communicating History Acoustic Transponder) tag. Implanted in belly walls to log the shark's position and depth, the CHAT tags upload their information to underwater receivers, usually placed in shallow bays, which are retrieved every three weeks. "We know they don't stake out declared territories. They are inter-island travelers," says Holland...
...tiger shark generally hunts at night. It is an indiscriminate eater, "willing to try anything for food," says Rocky Strong, a shark biologist associated with the Jean-Michel Cousteau Institute. Not just fish, turtles and sea mammals but also dogs, boots, beer bottles and unopened cans of beans. Its teeth are serrated, with a notch to catch and cut through ligament or shell tissue...
...were protected in the 1970s. "Turtles come close to the shore, and the tigers follow them to prey on them. That puts them in the same area as swimmers and surfers." Tigers are slower swimmers than great whites and not as good at surprise. Human victims often see the shark before it closes in to attack. But tigers are persistent. "If you are bitten by a tiger, you have a good chance of being chewed up. They come back," says John McCosker, a scientist at the California Academy of Sciences...
...BULL SHARK When Dawn Schauman was attacked by an 8-to-10-ft. bull shark in October 1993, she said, "it felt like a truck had slammed into me, then I felt a compacting squeeze and an acute burning in my left hand and my left leg." The shark spun her around, leaving her disoriented as she hemorrhaged blood into the water. The shark left, and willpower alone got Schauman--6 1/2 months pregnant--back to shore. Her baby was later born prematurely but safely. For months Schauman woke at 3 a.m. replaying the attack in her head...
...bull shark, Carcharhinus leucas, usually grows no longer than 10 ft. and weighs up to 500 lbs., but what it lacks in size it makes up for in aggressiveness. Experts regard it as the most pugnacious of sharks. It has, according to Robert Hueter, director of the Center of Shark Research at the Mote Marine Laboratory in Sarasota, Fla., the highest level of testosterone in any animal, including lions and elephants. Its lower spiked teeth are designed to hold prey while the upper triangular serrated teeth gouge out flesh. "The bull is an ambush type of predator, it makes this...
