Australian researchers have tested new bite-resistant wetsuits that minimize injuries from shark bites. The materials, made with chain mail, Kevlar, and nanofibers, help reduce bleeding and improve safety for surfers and divers. The innovation marks a step forward in shark bite protection without limiting flexibility underwater.Australian researchers have tested new bite-resistant wetsuits that minimize injuries from shark bites.
