You have probably seen photos of these goofy looking wetsuits already. You probably even caught that these are supposed to stop sharks from attacking or to be more precise to make you less probably being mistaken for a seal or something else that shark would deem delicious. Here is some more info on how these work.
Surf entrepreneurs Hamish Jolly and Craig Anderson have paired up with The Oceans Institute at the University of Western Australia to develop wetsuits that make beach goers look less like seals, and more like other tasteless ocean dwellers.
The first wetsuit, the “Elude,” is designed to make swimmers and snorkelers blend into the water around them. The suit’s “disruptive coloration and shaping” is difficult for sharks to distinguish from the surrounding environment, thus decreasing the likelihood of an attack.
The “Diverter” was created especially for surfers, and is intended to make users appear as a dangerous or unlikely food choice for sharks. The suit is marked with large white and dark blue stripes, much like that of the striped pilotfish which lives in harmony with the animals. The company notes that the product is intended to repel sharks, but that it should be treated as a tool for providing enough time to exit the water if a shark comes in close range.
The technology behind the designs is quite sophisticated. The wetsuits use scientific data about sharks’ vision to effectively manipulate how sharks perceive swimmers in the water. Shark Attack Mitigation Systems (SAMS) translates this data into a combination of variables. These include contrasting colors, shapes, and sizes that combine to create unique visual effects at different depths and distances.
The designers have used this information to determine which patterns would most effectively impact sharks’ vision in the water, all while maintaining a trendy aesthetic.
