JAWS Strikes Again

"It is typical for a great white to swim up to someone at a relaxed pace, take a bite, then swim off," said Collier. This contrasts with the torpedo-like attacks on the seal, suggesting that the shark's goal is not predation.

Teeth Like Hands

"Great whites are curious and investigative animals," said Martin. "That's what most people don't realize. When great whites bite something unfamiliar to them, whether a person or a crab pot, they're looking for tactile evidence about what it is."

A great white uses its teeth the way humans use their hands. In a living shark, every tooth has ten to fifteen degrees of flex. When the animal opens its mouth, the tooth bed is pulled back, "causing their teeth to splay out like a cat's whiskers," said Martin.

"Combine that with the flexibility of each tooth, and you realize a great white can use its jaws like a pair of forceps. They're very adept at grabbing things that snag their curiosity."

Great whites are also sharp sighted, further evidence that they do not mistake humans for other prey. Scientists believe that sharks see as well below the surface as humans do above it. And they see in color.

"I've seen these sharks swim 70 feet (21 meters) to the surface to investigate a piece of debris no bigger than the palm of my hand," said Martin. They are also known to take bites of buoys, paddle boards, kayaks, zodiac boats, and other man-made objects floating in the ocean.

"Everyone wants to think sharks just search out seals, but they bite a lot of things that don't resemble any of their known prey," said A. Peter Klimley, an expert in marine animal behavior at the University of California, Davis, and author of the Secret Lives of Sharks and co-author of Great White Sharks: The Biology of Carcharodon carcharias. "They don't tear these things to pieces. They take a bite, feel them over, then move on."
