"We can't train sharks to do us the favor of not being sharks when we are invaders in their natural habitat," Burgess said. "We pride ourselves on being smart animals, so why not use some of that intelligence to avoid shark attacks?" He offered these additional attack-prevention strategies:
Consider your clothing: avoid wearing shiny jewelry, because the reflected light resembles the sheen of fish scales.
Avoid brightly colored or patterned clothing, because sharks see contrast particularly well.
Avoid entering waters with sewage output or entering the water if you are bleeding. Such additions to the water can act as strong olfactory attractants to sharks.
Know your facts! Porpoise sightings do not indicate the absence of sharks. In fact, the opposite is often true. Also be on the lookout for signs of bait fishes or feeding activity -- diving seabirds are good indicators of such action. Animals that eat the same food items are often found in close proximity. Remember, a predator is never too far from its prey.
Refrain from excess splashing while in the water, and do not allow pets in the water because of their erratic movements.
Exercise caution when occupying the area between sandbars or near steep drop-offs, as these are favorite hangouts for sharks.
And, of course, do not harass a shark if you see one!
