Much attention is placed on the danger that sharks represent to humans. Our hearts are with all attacks survivors and victims, most of whom are ocean lovers like ourselves. However, it is essential to place the threat that sharks represent to humans in perspective. We find the below infographic (supplied by Mark Porter at Shark Facts) to be incredibly enlightening and informative. It vividly compares the respective threats of humans to sharks verses sharks to humans.
A word from Steve the shark…
“Ok, our relationship (eds. note: sharks and humans) has been a little trying over the past. But many of your best and brightest are running or developing awesome bather protection programs designed to allow both humans and sharks to live in peace! learn and support these programs – we will all benefit”.
Eco-friendly bather protection initiatives
The Shark Spotting Programme, in Cape Town, is the only program of its kind in the world. It attempts to balance the needs of both people and white shark conservation by pro-actively reducing the interaction and conflict between recreational water users and sharks. It uses the cliffs and mountains surronding Cape Towns beachers to enable human spotters to watch and warn bathers of big sharks approaching. Since its implementation, shark attack rates have dropped dramatically in Cape Town.. and no sharks killed!

Natal Sharks Board is a controversial orginisation mandated to protect humans from sharks in the kwaZulu Natal province. Traditionally the use of gill nets and baited drumlines have been used to cull local populations. But in recent years the board and government has been developing an electric barrier that will be 100 percent non-invasive! This great initiative has been getting successfully tested with our sister inititute ‘Oceans Research’ on great white sharks in Mossel Bay.

Do you know that magnets can be used to deter sharks? Wonderfully these magical magnets do not need to be recharged! the sharkbanz initiative was developed to offer surfers and other waterusers a easy and convienant method of personal safety. Wrist and leg bands fitted with magnets have been tested and prove effective at keeping a curious shark at bay.

The SharkShield™ generates an electrical field that is detected by the shark through its sensory receptors, known as the Ampullae of Lorenzini, found on the snouts of all predator sharks. These devices are worn on your person, and are used extensively surfers, divers, spearos and other water users.

FAQ's about Shark Attacks and Sharks
Why do sharks attack?
Sharks do not normally hunt humans. When they do attack a human, it is usually a case of mistaken identity. Shark sometimes mistake humans for its natural prey, such as fish or a marine mammal or sea turtle, and most often will release the person after the first bite. The majority of shark bites are “hit-and-run” attacks by smaller species, such as blacktip and spinner sharks. They mistake thrashing arms or dangling feet as prey, dart in, bite, and let go when they realize it’s not a fish. The “big three” species — bull, tiger, and great white sharks –are big enough to do a lot of damage to a human and must be treated with respect and caution.
Is there an increase in shark attacks?
In 2001, there were 76 recorded unprovoked shark attacks in the U.S., versus 86 in 2000. According to the International Shark Attack File, the numbers of shark bites from year-to-year seem to be directly associated with increased numbers of humans swimming, diving and surfing in the ocean. Some shark populations have been on the decline since the mid-1980s, when the commercial fishery for sharks became a booming industry. Current regulations are working to reverse the trend of declining shark populations in the U.S., although some species are still depleted, and to maintain the shark populations that are healthy.
How can I reduce the chance of been attacked?
Please remember, that shark attacks are incredibly rare, and as always you remember that when entering the water, ensure you are safe from rip currents, rough seas, and boat traffic as you are far more likely to encounter trouble from these dangers than a shark. However, sharks are predators, and there are a few things (other than staying out fo the sea) that you can do to minimise the chance of bite
- Always stay in groups since sharks are more likely to attack an individual. Do not wander too far from shore — this isolates you and decreases your chance of being rescued.
- Avoid being in the water early in the morning and during darkness or twilight hours when sharks are most active and searching for food.
- Do not enter the water if bleeding.
- Avoid wearing shiny jewelry because the reflected light resembles the sheen of fish scales.
- Avoid waters being used by sport or commercial fisherman, especially if there are signs of bait fishes or feeding activity. Diving seabirds are good indicators of such action.
- Use extra caution when waters are murky and avoid bright colored clothing — sharks see contrast particularly well. Refrain from excess splashing.
- Exercise caution when occupying the area between sandbars or near steep dropoffs — 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 seen while there. And do not approach a shark if you see one.
- Chat to locals about sharks. Sharky waters are often well known, and beaches where sharks frequent can easily be avoided by asking a few questions.
- If you are entering waters known for an abundance of large sharks, consider using personal safety devices such as the SharkShield or Sharkbanz.
Why should we bother with protecting sharks?
Sharks are awesome creatures whose biology has remained virtually unchanged for millions of years. Just as humans strive to protect other living creatures from becoming threatened or endangered, it is our duty as stewards of the Earth to protect all ocean life, including sharks. As top predators in the sea, sharks provide a valuable balance to the marine ecosystem. People are one of only a few species that prey on sharks (killer whales and other sharks are others), killing over a hundred million per year. We must support and abide by fishing regulations that were put into place to ensure that sharks will thrive in the ocean for millions of years to come.
How common are shark attacks?
More people are killed each year by electrocution by Christmas tree lights than by shark attacks. Think about the things you would do to minimize your family’s risk of being harmed by Christmas tree lights. You’d unplug the lights at night and never leave them unattended. You’d keep your tree moist to prevent a fire. Maybe you’d educate your children about the potential of electric shock if they improperly plugged in the lights. Similarly, you can take precautions that minimize your risk of encountering a shark when visiting the beach this summer:
How do sharks attack people?
According to author Murray Suid and George Burgess, a senior biologist and director of the International Shark Attack File, there are four basic types of shark attacks on humans. The first and, by far, the most common are provoked attacks. These occur when people in some way touch, or otherwise disturb, sharks. Fishermen removing sharks from their nets, for example, might lose a finger or limb if not careful. Sometimes divers have taunted or tried to grab a shark, with not-surprising consequences.
Unprovoked attacks can happen in three principal ways. The most frequent of this type are hit-and-run attacks — when the shark grabs, releases and leaves the scene. The shark could be investigating the individual, thinking he or she was its usual prey. It might also perceive the individual as a threat, similar to how a more aggressive, yet fearful, dog could attack anyone who mistakenly treads on its turf. The two other types of unprovoked attacks are sneak attacks, when a deep-sea shark moves upon a diver unawares; and, finally, bump-and-bite attacks, when a shark head-butts a person before it takes a bite.
