The reaction of surfer Mike Fanning when he managed to escape from the jaws of a shark shows that good luck is the key to survival after an attack by the predator of the oceans.
However, as the British newspaper Guardian, there are things that swimmers can do to reduce their already small risk of being hit by a deadly shark.
First something fundamental: In all scenarios, being attacked by a shark are extremely bad. A study last year showed that there is one possibility in trirthy times you swim off the coast of Perth in the summer to have a shark attack.
“You go into a wild environment, so therefore there is risk, but a small risk,” Dr. Daniel Bucher, marine ecologist at the University of Southern Cross, supports.
“To see a shark while surfing is rare, attacking you is even more rare. To go out in the ocean does not mean that you should be panic, “he says.
As stated, there are factors that increase the probability of encountering a shark. The swim alone or estuarine especially after a heavy rain, or in an area that there is great feeding activities from dolphins or birds may increase the risk. To swim, is also a factor especially when it comes to shark “bull.”
Sharks do not tend to devour people, probably out exploratory bites to see if the selected target is their appropriate prey. That’s why most bites are on the feet of people.
“Swim quickly and smoothly”
There have been recent technological innovations in the outfit and the board of a surfer to create a visual deterrent for sharks.
However if you still find yourself faced with a shark the best thing to do is in accordance with the University of Florida, “to get away of the water and swim quickly but calmly.” The ideal situation would be not being alone but with someone else so you do not become the only objective.
Studies undertaken by Bucher and other researchers in the US, show that sharks tend to hunt their targets pleasing to flee, but will stop if faced with something like this did Fanning.
“If their prey face them then sharks tend circling,” Bucher says. “If there is a white shark six to seven meters long then you can not do much, but a younger animal about three meters is not customary to eat large animals and therefore will be more careful.”
The recorded file on shark attacks, suggests you to stand with your back to a rock or reef and hit the shark with an inanimate object. A bump on the nose is often a deterrent.
Last year a doctor managed to repel a shark with the help of a knife, on the south coast of New Zealand.
Fanning also said hit shark several times, which can also be effective but with greater risk. “To pretend the dead” does not work as a strategy, so try to take the punch and leave as soon as possible.
“The attack is the best defense,” Bucher says.
He even argues that even if a shark will bite you then there is hope. From the 72 attacks, for example, recorded last year worldwide, only three have been fatal.
