American chemist Eric Stroud claims to have found a substance that can scare away the ocean's most fearsome predators : sharks. And the most curious thing is that it does not do it to protect us from their bites, but to protect them from overfishing and thus contribute to their conservation.
His company SharkDefense is making magnets made of iron, boron and neodymium to repel sharks . According to the researcher, sharks have electrical sensors in their snouts called Lorenzini blisters, and biologists believe that sharks use them to detect the heartbeat of their prey and to navigate using the Earth's magnetic field. By waving a magnet in front of a shark, possibly those electrical sensors are disturbed. It is something that blinds them, like a ray of light, clarifies Stroud. Your company also manufactures smart hooks (smart hooks English) magnetized and coated with a rare metal such as samarium, neodymium or praseodymium. Some trials with this system show a reduction of between 60 and 70% of the sharks caught.
