Extensive research on a shark deterrent wetsuit has determined that specific contrasting patterns actually deter sharks. These modifications on shark deterrent wetsuits are constructed in hopes of preventing future accidental attacks on humans. The popular show Ted Talks featured Hamish Jolly, an ocean swimmer and entrepreneur, on a segment informing us that there are biological warning signs ingrained into sharks neurological systems. The contrast of black and white stripes actually caution sharks along with many other marine life. Australian naturalist Harry Butler believes this is because warning colorations and banding patterns are notorious in various venomous sea creatures.
In addition, mapping out the characteristics of a shark’s eye also derived the technology and pattern of the suit. According to the video, sharks only see in black and white or gray-scale. Scientists use complex computer modeling, which allows them to view what sharks see at a variety of depths, water clarities, distances, and various light conditions. With these results, researchers are able to determine the most effective contrasting shades for the new and improved shark repellent wetsuit. Scientists tested this theory by filling two encased perforated drums with chum, covered them with different colored neoprene, and submerged them into the water. The exciting results reflected that sharks showed more interest in the black neoprene suit as opposed to the striped suit. Scientists working on this project confirmed that baiting the rig changed the sharks behavior, however it was essential to provoke some form of interaction in order to complete their study.
