WebbMost unique is its electromagnetic sense. This is facilitated by pores known as "ampullae of Lorenzini" that are concentrated around the snout. As sharks move through the earth's magnetic field, they create an electric field. By sensing this field, they can detect the strength and direction of it. This is the grey reef shark's navigation system. Webb13 feb. 2024 · Electroreceptors are most often used to capture prey, by the detection of electrical fields generated by the prey. For example, this allows sharks to find prey hidden in the sand. Some fish have ...

Webb28 aug. 2024 · Magnets repel sharks, studies show, by interfering with their ability to sense electrical fields. A recent study shows that magnets placed on the nets can repel sharks and rays from entering the trap. Shark-repelling magnets may be the perfect antidote to unwanted shark attention while fishing. Can sharks detect electromagnetic fields? Webbcessful bait strike was recorded when a shark engulfed a bait in its mouth. To examine whether our magnets were too powerful (and so potentially overwhelming the sharks’ electromagnetic senses), we conducted three additional trials of much smaller, weaker cylin-drical rare earth magnets.
