Bite-resistant wetsuit could help surfers survive shark encounters

An Australian study led by Flinders University researchers has demonstrated that bite-resistant wetsuit materials can significantly reduce the severity of shark bite injuries, particularly from white and tiger sharks—two species responsible for many unprovoked and fatal attacks. The research tested four advanced materials—Aqua Armour, Shark Stop, ActionTX-S, and Brewster—made from ultra-high molecular weight polyethylene, a strong yet flexible fiber. These materials were evaluated using foam-padded “bite packages” exposed to real shark bites in South Australia and Queensland. The results showed that all tested materials effectively prevented shark teeth from puncturing through the fabric, reducing substantial and critical damage compared to standard neoprene wetsuits. While these bite-resistant wetsuits do not eliminate all risks, such as internal injuries, they can reduce blood loss and trauma from severe lacerations and punctures, potentially saving lives. This innovation addresses the limitations of existing protective gear like chainmail suits, which are heavy and inflexible for typical water sports. The study
