Sharks are terrifying ocean hunters, but people are rarely on their daily menu. In fact, the odds of a shark attack are rather low. Nonetheless, if precautions aren't taken sharks can be bad news, and anyone who entering their neighborhood should hold a healthy respect for these fearsome predators. If going into waters populated by sharks, it's a good idea to know how to fend off a shark attack, and it's even more important to know how to decrease the risk of an attack beforehand.
The best way to avoid a shark attack is to stay away from where sharks normally lurk. Sharks are not limited to the ocean, they are also found in estuaries and coastal rivers and lakes. The Bull shark, for example, can be found even in fresh water, and these large predators have also been known to travel water channels far inland. In some cases, they have been spotted as far as up to 2,500 miles (4,000 km) inland in the Mississippi River as Illinois.
Avoid deep drop-offs as well as the areas in between sandbars. Both are preferred hunting areas for sharks. Avoid contaminated waters near sewage discharges. Sharks have a keen sense of smell and will naturally be attracted to these areas. Stay away from the nearby fishing action. Sharks often like to nibble on fisherman's bait. Additionally, the smell of discarded fish remains acts as a powerful attractant. Sharks are equally attracted to other fish feeding areas. Watch for seabirds diving into the water, this indicates feeding activity and is an area to avoid.
Stick to non-bright swimming suits.
Bright or shiny colors can draw sharks. Don't wear jewelry, because their reflection may be perceived by sharks as fish's scales, and put you on the lunch menu.
