Sharks
Questions about sharks are among the questions most frequently asked to lifeguards. Sharks are a potential danger that must be acknowledged, but things should be kept in perspective. Many more people are injured and killed while driving to and from the beach than bitten by sharks and shark bites are less common than such beach related injuries as spinal damage, dehydration, jellyfish stings, sunburn, and lightning.
Ocean lifeguards are trained to look for dangerous marine life. When they spot a shark in close proximity, all bathers will be called out of the water, and the double red flags will be flying from the lifeguard towers.
Dr. George Burgess, Director of the International Shark Attack Files at the University of Florida, Florida Museum of Natural History says the chances of interacting with a shark can be reduced if one heeds the following advice:
- Always stay in groups since sharks are more likely to attack a solitary swimmer.
- Do not wander too far from shore where you will be isolated and far away from assistance.
- Avoid the water during darkness or twilight hours when sharks are most active and have a competitive sensory advantage.
- Do not enter the water if bleeding from an open wound or if menstruating – a shark’s olfactory ability is acute.
- Do not wear shiny jewelry because it reflects light and resembles the sheen of fish scales.
- Avoid waters with effluents or sewage and those being used by sport or commercial fishermen, especially if there are signs of bait fish or feeding activity. Diving seabirds are good indicators of the presence of fish.
- Porpoise sightings do not indicate the absence of sharks – both often eat the same food items.
- Use extra caution when waters are murky. And remember that sharks may be attracted by contrasting colors such as bright swim suits or uneven tans.
- Refrain from excessive splashing, and do not allow pets in the water because of their erratic movements.
- Exercise caution when occupying areas between sandbars or near steep drop offs as these are favorite hangouts for sharks.
- Do not enter the water if sharks are known to be present and evacuate the water if sharks are sighted. And, of course, do not harass a shark if you see one.
