Just adding to this they also feel by biting like we do with our hands so often its not even a hunger response but mere curiosity.
just adding to this why do u think in a great many case ppl are able to get away with either minor injuries or missing limbs? the extent of damage is
not at discussion here, just the plain fact that ppl are able to get away at all. do u seriously think that a hungry man eating shark would not get driven into a frenzy after blood is let from the wound and/or missing body parts? what's to stop them from eating the whole person? why are certain ppl able to be rescued after the attack instead of getting torn to bits and pieces? this proves in many cases the shark was merely having a nibble/taste..
and if you want facts and statistics, here are some relevant to this discussion taken from the
national geographics website:
• Each year there are about 50 to 70 confirmed shark attacks and 5 to 15 shark-attack fatalities around the world. The numbers have risen over the past several decades but not because sharks are more aggressive: Humans have simply taken to coastal waters in increasing numbers.
• Over 375 shark species have been identified, but only about a dozen are considered particularly dangerous. Three species are responsible for most human attacks: great white (Carcharodon carcharias), tiger (Galeocerdo cuvier), and bull (Carcharhinus leucas) sharks.
• While sharks kill fewer than 20 people a year, their own numbers suffer greatly at human hands. Between 20 and 100 million sharks die each year due to fishing activity, according to data from the Florida Museum of Natural History's International Shark Attack File. The organization estimates that some shark populations have plummeted 30 to 50 percent.
• While scientists still have much to learn about shark migration, researchers do know that some species get around. Blue sharks (Prionace glauca), for example, roam the North Atlantic on journeys of 1,200 to 1,700 nautical miles (2,220 to 3,145 kilometers). After one record-breaking blue was tagged off New York, it swam 3,740 nautical miles (6,919 kilometers) to Brazil.
• Some sharks must swim constantly to "breathe" oxygen from water passing through their gills. Other species can achieve this while stationary.
• The media can have a voracious appetite for "shark bites man" stories. The summer of 2001, for example, saw an explosion of shark-attack hype and was even heralded on the cover of Time magazine as the "Summer of the Shark." Yet 2001 was statistically average: The year saw 76 shark attacks and 5 fatalities worldwide, compared to 85 attacks and 12 fatalities in 2000.
• Thirty years ago the blockbuster Jaws brought the terror of shark attack to movie theaters. The record-breaking film, directed by Steven Spielberg and based on a best-selling novel by Peter Benchley, grossed nearly 130 million dollars (U.S.) in the United States alone. The movie arguably made sharks public enemy number one.
