While shark attacks are rare it’s safe to say anybody who spends a lot of time enjoying activities like diving or surfing would prefer to avoid that fate. Using the sophisticated science behind shark vision Hamish Jolly, an Australian swimmer, came up with wetsuit designs that actually deter shark attacks. In the video the science behind the design is explained along with the test results using two predatory sharks (the great white and tiger sharks). It’s a pretty fascinating watch and might change the designs of wetsuits forever. Check it out below.
