Sharks have been known to attack humans when they are confused or curious. If a shark sees a human splashing in the water, it may try to investigate, leading to an accidental attack. Still, sharks have more to fear from humans than we do of them.
It is important to remember that sharks don't enjoy eating humans though, and once realising that you're not a tasty seal or fish they'll more than likely leave you alone.
The vast majority of sharks are harmless too. Only four out of the 400 different types of sharks have a reputation for unprovoked attacks on humans (great whites, tiger sharks, bull sharks and oceanic whitetips). The media portray sharks as mindless killers, but that's simply not the case.
ESDs aim to overwhelm a shark's electro-sensory system. They emit electrical pulses (each one does so in a different way) that are supposed to repel the shark. So far, ESDs have been the most effective type of personal shark repellent.
It has traditionally been believed that sharks are repelled by the smell of a dead shark; however, modern research has had mixed results. The Pardachirus marmoratus fish (finless sole, Red Sea Moses sole) repels sharks through its secretions.
Go for the shark's most sensitive areas – its nose, its gills, and especially its eyes. Dig in and keep pressing until it lets you go. Remember that sharks will often thrash around once they have a bite, so if you can, give it a “hug”.
What does a shark attack feel like? While each survivor describes the experience differently, a common description from shark attack survivors is the attack feels similar to being punched or bumped. Some survivors have even recounted no pain at all!
Most attacks world-wide happen between 8.00 am and 6.00 pm and mostly on weekend during the warmer seasons of the year.
Despite the old saying that aiming for the snout is the best strategy, a shark's most sensitive areas are really its eyes and its gills. Aiming for the nose, which is not known to be a weak spot, is generally considered a bad idea.
If a shark attacks, the best strategy is to hit it on the tip of its nose.
A shark's most acute sense, the one it may use to detect prey from the greatest distance, is probably its sense of hearing. Sound travels faster and farther in water than in air. The general structure of a shark's internal ear resembles that of humans, but a shark's is much more sensitive.
Bump and bite: Bump and bites usually start with the shark circling around you, then they will engage by bumping into you then taking a bite. Usually this is like a hit and run where a shark is motivated by curiosity or sometimes, territorialism.
Alternatively, divers and swimmers can probably reduce the chance of an interaction with a shark by avoiding bright and highly contrasting swimwear or dive gear. We personally prefer to use dark blue or black fins, mask, tank, and wetsuit while diving.
Since sharks see contrast colors, anything that is very bright against lighter or darker skin can look like a bait fish to a shark. For this reason, he suggests swimmers avoid wearing yellow, white, or even bathing suits with contrasting colors, like black and white.
Pinnipeds (seals and sea lions) aren't the only marine mammals that have snacked on a shark. The sperm whale is a marine mammal that is considered an apex predator in certain habitats and it has been recorded as having eaten shark eggs.
This myth is often associated with a shark safety tip: “If you see dolphins, it's safe to swim there because their presence scares away sharks.” This is simply not correct. In fact, sharks and dolphins are often found near each other for a simple reason—they eat the same food, and both go where the food is.
What are the chances of a shark encounter? The chances of a shark encounter are very small compared to other animal encounter, natural disasters and ocean-side dangers. Most shark attacks are simply due to mistaken identity. Worldwide there is an average of 50-70 shark attacks every year.
Rapid, irregularly-pulsed sounds at low frequencies (below 600 hertz) similar to those made by injured prey or a group of spawning fish can alert a hunter such as a bull shark from over 1.6 km (1 mile) away. At 100 m (330 ft), a shark's lateral line system kicks in.
Just like we check under our beds for monsters, sharks check for dolphins before nodding off. That's right, the toughest kids on the undersea block swim in fear of dolphins. Here, we've compiled a splash of facts to tell you why.
