But recently a company that makes those goofy looking “shark-deterring” zebra wetsuits did a study that they claim proves their patterned suits work. According to the Shark Mitigation Systems, an Australian company that makes a variety of shark deterring products, their patterns do indeed work.

Shark attacks are more likely to occur at dawn and dusk, precisely when they’re more active searching for food. Also, because the visibility is limited during the twilight hours, sharks may mistake you for prey animals or enemies. That is why you must avoid surfing alone in shark-infested waters.

A sharp object is a good way to inflict enough pain to scare away the shark. Aim for the head, specifically the eyes or the gills. If you do not have a weapon, improvise. Use any inanimate object, such as a camera or a rock to ward off the shark.

The researchers have added magnets to netting used to create shark fences, and in some experiments they’ve seen a 95 percent reduction in the sharks entering through holes in the netting. They’ve also placed magnets above hooks on long fishing lines, he says, “and we’ve reduced shark catch by 50 percent.”

Magnetic shark repellents utilize permanent magnets, which exploit the sensitivity of the Ampullae of Lorenzini in sharks and rays (electrosense). This organ is not found on bony fish (teleosts), therefore, this type of shark repellent is selective to sharks and rays.

You can think of a magnet as a bundle of tiny magnets, called magnetic domains, that are jammed together. Each one reinforces the magnetic fields of the others. Each one has a tiny north and south pole. If you cut one in half, the newly cut faces will become the new north or south poles of the smaller pieces.

Can Sharks Smell Fear? No, they can’t. The sense of smell of a shark is strong, and they can smell everything that interacts with their sensory cell on their nares, but this doesn’t include feelings such as fear. But you need to remember that sharks don’t rely only on just their sense of smell.
