Researchers have been evaluating the effectiveness of new bite-resistant wetsuits designed to mitigate injuries from shark attacks. 

The testing involved simulations against great white and tiger sharks, species identified as being responsible for the majority of unprovoked bites.

The research, conducted by Flinders University in South Australia, assessed four different bite-resistant materials with the aim of reducing injuries and blood loss. 

“I was genuinely surprised with how much of the damage was reduced and eliminated,” said Professor Charlie Huveneers, a researcher involved in the project.

The wetsuits incorporate a strong, lightweight fibre to maintain flexibility and comfort for activities such as surfing and diving.

“It incorporates a high molecular weight polyethylene which is just a fancy word for the fibre that is extremely strong but very light,” Huveneers said. 

The design is based on the understanding that fatalities from shark attacks are often from blood loss or shock.

“The ability to reduce blood loss could save life,” Huveneers said.

The research comes at a time when shark attack fatalities are a growing concern. 

This year, there have been nine fatal shark attacks globally, with four in Australia, in New South Wales, Queensland, Western Australia, and South Australia. 

The most recent fatal attack in SA occurred in January at Granites Beach on the West Coast.

Mason Smith, a surfer, highlighted the anxieties surrounding the sport.

“Surfing alone, I definitely get a bit nervous and eerie that there’s a shark,” Smith said. 

” … It’d make me feel heaps more comfortable wearing a shark resistant wetsuit.”

The findings of the research are expected to contribute to the ongoing efforts to improve ocean safety and reduce the risk of shark-related injuries.

“Nowadays with all the different technologies and devices available we are at the point where we can reduce the risk of shark bites,” Huveneers said.
