Re:sharks avoidance wisdom - 2009/03/12 20:23 lol DrC, maybe it's possible to modify the DNA of whites so they act as guards against other sharks and keep surfers safe from attack. i reckon we'd have to splice the DNA of a white with that of a bouncer who used to work at the north steyne hotel in manly. in this case the genetically modified whites would keep any troublemakers (sharks, goat boaters or blow-ins) out of the line-up. hey, the modified whites could even moonlight doing tow-ins and rescues. i could even have my own pet white bodyguard to go surfing and diving with.

Not enough stuff? Let me know, I can post a few hundreds of links more...

Re:sharks avoidance wisdom - 2009/03/13 13:38 The reality is you are more likely to die in a car accident driving to the beach than you are in the water from a shark attack.In the last 10yrs. in the U.S.there has been a total of 17 fatalites due to shark attacks.That number pales to the number of people dieing from dog bites which is over 200.You are 30 times more likely to die from being struck by lightning.The estimate is 5-15 deaths annually Worldwide from shark attacks.Most shark attacks are of the "hit and run" variety and are not considered life threatning.There are 3 species of sharks that are the most dangerous beacause they are larger in size and go after larger prey.That is the Great White,the Bull Shark,and the Tiger Shark.If we could somehow monitor where these sharks are most prevelant so bathers and surfers can avoid those areas I believe it would reduce the # of deaths.I believe fishermen know what types of fish are running in there areas and a reporting system might accomplish that.

Re:sharks avoidance wisdom - 2009/03/13 19:27 hi Surdog, there's some excellent data being collected on the travels of tagged whites and tigers. man, those sharks do some miles here and there and all over the ocean but they tend to keep to patterns of movement which likely equate to seasonal movements of food sources and reproduction opportunites. a bit like myself really and best for us not to get in between them and their food or their fun.

somebody famous once said, "lies, dammed lies and statistics" and i think it's wise to get stat's in perspective. think about the number of deaths caused by lightning stikes and the number of people actually outside during an electrical storm. the odds are getting higher. how many of them died with a golf club in their hand, doing something they love doing? the odds are getting higher. think about the number of dogs in the neighbourhood and the number of people attacked by them who actually die as a result. once bitten, the odds of dying from a shark bite are much higher than the odds of dying from a dog bite.

also, it may be misleading to dwell upon just the number of deaths proven to be caused by shark attack given there's a whole bunch of unproven but suspected shark attack deaths which can't be added to the stats. unlike deaths caused by lightning strike which leave a crispy crita, deaths caused by shark attack may leave no evidence. even when someone goes missing and part of them turns up months later in the belly of a tiger, the cause of death may not be proven apart from reasonable suspicion that those neatly limbs or bound hands which keep turning up in the belly of sharks are probably not the product of an attack on a living person.

the odds seem to be against shark attacks but i don't think that random chance has as much to do with the equation as we may think. fact is, most of us are intuitively aware of the odds given several circumstances and most of us don't take extreme risks most of the time when it comes to surf and sharks. i think the argument here is about what is the best way to reduce the potential for and frequency of shark attacks given that is the best solution for surfers and for sharks. possibly, fitting all man eaters with tracking tags and monitoring their whereabouts may help.

Re:sharks avoidance wisdom - 2009/03/14 16:59 Element,
I think you are caught up in media histeria. Think about the number of peeople that are in the ocean at any given day worldwide and tell me if you think 5-15 deaths yearly from shark attacks is something that is not relevant.I hate to keep repeating myself but it is a known fact that most shark attacks are hit and runs which means the shark mistakes your foot for bait fish discovers it is not and lets go.These types of attacks are not life threatning.Dog attacks on the other hand can be considerably more vicious and result in face disfigurement and other serious injuries and they more frequently result in death.In the last 10 years in the United States from 2000-2010, 17 fatalaties from sharks.Think about the number of people that have gone in the ocean during that time frame it is in the millions.The number of drownings per year far exceedes the number of shark deaths.

Re:sharks avoidance wisdom - 2009/03/15 00:07 The examples I am referring to are the many postings about shark bites in Australia. Even people following the above rules were bitten. Just pointing out that they aren't foolproof.

The bravery was directed at those who rescue others from shark attacks, not at those who warns people about them.
