Humans are much more dangerous to sharks, which tend to end up in soup or medicine. Fishing nets tangle and drown about 100 million sharks each year. In California there is only one shark attack for every 1 million surfing days, according to the Surfrider Foundation. You are 30 times as likely to be killed by lightning. Poorly wired Christmas trees claim more victims than sharks, according to Australian researchers. And dogs--man's best friends--bite many thousands more people than sharks...
Scientists ultimately hope to de-mythologize sharks, to erase their images as rogue man-eaters like the great white shark that figures in Jaws, the Peter Benchley novel turned Steven Spielberg movie classic. Benchley, who says he is now "a full-time ocean conservationist," told TIME last week, "I couldn't write Jaws today." After 25 years of research, the demonization of sharks doesn't hold, he says. "It used to be believed that great white sharks did target humans; now we know that except in the rarest of instances, great white shark attacks are mistakes." Dr. Robert...
...Sharks are one of nature's ultimate designs, tested over 400 million years--confident, sleek and lethal (see graphic). Studies show some sharks can measure changes in electric currents as tiny as five-billionths of a volt. They use this ability to hunt for prey hidden under the sand and to navigate according to the earth's magnetic field. "They are like some high-tech AWACS thing, with all their sensors," says Sean Van Sommeran, executive director of the Pelagic Shark Research Foundation in Santa Cruz, Calif. When they do attack a human, the weight of evidence now suggests, they...
...GREAT WHITE Scott Yerby never saw the great white shark before it attacked him as he surfed off Clam Beach near Eureka, Calif. "This thing jumped me--it had enough force to lift me right out of the water. It was on my leg, I could see my femur, there was blood in the water--I knew then it was pretty serious," says Yerby, who was 29 at the time of the August 1997 attack. He hit the shark on the nose (the prescribed last-ditch defense, along with ripping at its gills), managed to get back on his board...
...Reyes Bird Observatory and the Hopkins Marine Center at Stanford University, is on the verge of finding where the great whites go after they leave the coast of California in the winter. Since 1999, the biologists have been attaching "pop-up tags" to great whites. These continually measure the shark's position, depth, speed and direction, and store the data in digital archives. After six months, the tiny computer in the tag sends an electric current through a magnesium burn wire, which dissolves in the seawater and allows the tag to pop up to the surface. The tag transmits...
