This Is the Only Proven Way to Deter a Great White Shark | The Swim

In the story of an epic journey through the Pacific, one particular character can quickly emerge. Ben saw it first, really; he was right on the bow of the boat three meters away — he was bigger than Ben. Before we left, we finally managed to contact a shark specialist to ask what to do with sharks. This expert was Dr. Charlie Heuveners, a biologist who works to uncover the secrets of shark behavior. Charlie and his team hope to find scientifically based ways to help sharks and humans divide the ocean. There are many situations where sharks and people will interact, be in the same area without any events. In general, some of these pelagic species are usually quite curious. Evolutionarily, if you live in the middle of the ocean, you need to be curious and explore random objects in order to survive. Unfortunately, it is difficult to be in the head of a shark to understand why in some cases the shark decides to attack. In the case of Ben, as with any other person, the overall risk from shark attacks is very, very low. Nevertheless, Ben will spend quite a lot of time in the water, swimming in a rather remote place, where the appearance of white sharks is more likely. Sharks have a terrible reputation. But only a handful of hundreds of known species can pose a threat to humans. However, the team consulted with Charlie about their options to reduce Ben’s risk of a dangerous collision. A deterrent is effective when it can reduce the risk of a shark bite. There are such things as chemical repellents, aimed at suppressing the smell, the smell of a shark; there are wetsuits that are trying to disguise the person who wears it; There is no silver bullet. It turns out that the very same supersensory adaptations that allowed these prehistoric predators to flourish in each ocean for 400 million years … can also be the key to how we can coexist with them today. The electromagnetic sense that sharks have is called the Lorenzini ampoule. These are small pores that are located on the face of sharks, which are filled with gel. This gel is conductive and allows you to transfer this electric field to the senses, and then process it with the brain. And this allows them to feel and detect a very weak electromagnetic field in the water. So, if sharks use these heightened senses to detect prey, can we develop technology that can use shark electromagnetic receptors to ensure the safety of both humans and sharks? To find this out, Charlie and his team put five different deterrents on famous shark dens and tried to lure the sharks in the direction of some tasty tuna. Two were based on electric fields. We had a total of 300 trials. During these tests, we tested about 44 sharks, interacting with our experimental equipment, and these sharks made more than 1,500 passes. The team found that only one of the tested deterrents had any impact on shark behavior: the Shark Shield, which targets sensitive ampoules. When you have a shield from sharks, it is very annoying sharks. At first they are curious and come close, but if they get too close, it will be like a very loud sound to your ear. You will not be near. It does not harm you, but it is a bit annoying. Without any deterrent, the shark took the bait that we presented to them in about 96% of cases. After we used this means of protection from the electric field, the proportion of bait taken by the shark was reduced to 40%. The crew keeps this device aboard the boat while Ben is swimming, but Ben did not need it during a recent peaceful encounter with a mako shark. But it seems that such a moment with a shark, which is not a machine that eats a person, is still quite difficult to imagine. Some studies suggest that the public tends to overestimate shark attacks by 10 or even 100 times. We know so little about this charming fish. We have over 500 different types of sharks, and of these there are still many species that are currently unknown. We do not even know their reproductive cycle. We do not even know where they fed. The reason I stay in the water whenever we have any marine life is to watch it and try to figure it out a little more. This is not about Jaws, the film that we all know. Sharks are not like that. Sometimes they are like us or animals; they are curious. When people basically dive for the first time with sharks, the first thing they say is “wow, that was impressive. It was wonderful”. They are more in fear than in fear. Ben’s sailing across the Pacific is amazing. Obviously, you know, he should be careful, but in most cases he will be very lucky if he can observe these animals in a natural environment that not many people will see.
