Researchers from the University of Western Australia have created a shark-proof wetsuit that is meant to keep sharks off you while surfing, swimming or diving. Unfortunately, the suit is not made of some magical fiber that can resist sharp teeth but relies on optic illusion. Since surfers get attacked by sharks mainly because they look like tasty seals in their regular wetsuits, the best way to avoid that is to change the way the sharks see them. The newly invented suit has either black and white stripes that will make surfers look like a poisonous prey to the sharks and thus warn them to stay away; the other type of suit is basically blue, meant for swimmers and divers, and its embellishment makes the wearer look invisible in the water to the colour-blinded sharks. The suit costs $500 and has been on sale for less than a couple of weeks so it’s too early to judge its effectiveness but here’s hoping.
