Scientists from Flinders University have developed and tested a new type of wetsuit material designed to reduce injuries from shark bites, offering what they describe as a “significant step forward” in ocean safety.
The project, led by Professor Charlie Huveneers, focuses on creating protective wetsuits that can withstand partial damage during a shark bite, allowing victims to survive long enough to reach medical assistance. The team’s findings were published in Wildlife Research in September 2025.
While the prospect of a “shark-proof wetsuit” may sound futuristic, Huveneers is careful to stress that this innovation is not about making the ocean completely safe. “It’s about improving survival chances,” he said. “Sharks will continue to behave as predators, but with the right materials, we can reduce the harm when encounters happen.”
Testing Shark Bites in Real Conditions
Unlike earlier studies conducted in controlled laboratory environments, the Flinders University team took their experiment directly to sea. Off the coast of South Australia, they lowered panels of different wetsuit materials into shark-infested waters. Each panel was baited with tuna to attract real great white sharks (Carcharodon carcharias) and tiger sharks (Galeocerdo cuvier).
The scientists then observed how the materials responded to the force and sharpness of shark bites. When the panels were retrieved, they found that the new materials — known as Aqua Armour, Shark Stop, ActionTX-S, and Brewster — had performed far better than traditional neoprene, the common material used in wetsuits.
Conventional neoprene tore easily, while the new fabrics, though punctured, remained largely intact. The tearing was shallow, and the fibers resisted shredding. This could mean the difference between a deep, life-threatening wound and a survivable bite.
“The main difference we observed was in wound severity,” said Dr. Tom Clarke, a co-author of the study. “The shark’s teeth still penetrated, but the material reduced tearing, limiting the area of potential bleeding. In some cases, that could save a life.”
The secret lies in ultra-high molecular weight polyethylene (UHMWPE) — an advanced synthetic fiber also used in bulletproof vests, high-strength ropes, and protective gear for aerospace engineering. UHMWPE is five times stronger than steel by weight but remains light and flexible, making it suitable for marine use.
By weaving these fibers into neoprene-like fabrics, researchers were able to create wetsuit panels that bend easily while maintaining resistance to cutting and tearing. Unlike metal-based alternatives such as chainmail, the UHMWPE wetsuit does not add significant bulk or weight, an important factor for surfers and divers who rely on mobility.
The innovation has already attracted attention from several wetsuit manufacturers looking to integrate the material into commercial designs. Early prototypes are being adapted for lifeguards, marine researchers, and professional divers who regularly enter shark habitats.

From Lethal Control to Coexistence
For decades, shark mitigation strategies in many coastal regions have relied on lethal methods, including shark nets, culling programs, and drumlines—baited hooks that trap and kill sharks. While these methods reduce local shark populations, they have also been widely criticized for damaging marine ecosystems and killing non-target species such as dolphins and turtles.
Huveneers said his team’s work offers a humane alternative.
“Rather than controlling shark populations, we focus on protecting humans directly,” he explained. “This approach supports coexistence without adding stress to already fragile marine environments.”
The development of shark-resistant wetsuits reflects a growing shift in conservation thinking. Scientists now emphasize coexistence with large predators rather than elimination. Technologies such as personal deterrent devices, sonar-based warning systems, and protective wetsuits form part of a broader “non-lethal” toolkit for ocean safety.
Globally, the number of unprovoked shark attacks remains relatively low. According to data from the International Shark Attack File, only 69 confirmed cases occurred in 2024, 11 of which were fatal. Most deaths, experts say, are caused not by the bite itself but by massive blood loss before victims reach shore.
This is where the new wetsuit could make the greatest difference. By limiting tissue tearing and preventing catastrophic bleeding, a diver or surfer could gain several additional minutes—often enough time to receive first aid or be rescued.
“Every second counts in a shark bite scenario,” said Dr. Clarke. “If we can extend that window of survival even slightly, the outcomes improve dramatically.”
Challenges Before Commercial Release
Despite the promise, several obstacles remain before shark-resistant wetsuits reach the mass market. The cost of production is one major barrier. UHMWPE fibers are expensive to produce, and integrating them into flexible, water-resistant fabrics requires specialized machinery.
Another challenge is comfort and usability. Surfers and divers prioritize flexibility, fit, and buoyancy. Heavy or rigid materials could deter adoption, regardless of how protective they are. The Flinders team is currently working with industrial designers to find the optimal balance between protection and performance.
There is also a need for standardized testing and labeling. At present, no global certification exists for “shark-bite-resistant” clothing, meaning performance claims vary widely between manufacturers. Establishing such a standard could help build consumer trust and prevent misleading marketing.
“We have to be realistic,” said Huveneers. “This technology reduces risk, but it doesn’t eliminate it. Large sharks can still cause crushing injuries even without breaking through the material.”
While the research primarily focuses on human safety, its implications extend to the tourism industry and marine conservation. In regions such as Australia, South Africa, and the United States, public fear of shark attacks often leads to temporary beach closures and economic losses for local communities.
By providing a safer environment for surfers and divers, shark-resistant wetsuits could help maintain public confidence and keep tourism economies stable. Furthermore, by reducing reliance on lethal control methods, the technology supports healthier ocean ecosystems.

Toward Safer Oceans
The research team plans to expand trials to include more shark species and varied environmental conditions. They are also exploring partnerships with wetsuit brands for large-scale production once the technology becomes affordable.
Even with these advancements, both Huveneers and Clarke caution that no wetsuit can guarantee complete safety. Swimmers and surfers are still advised to follow standard precautions: avoid entering the water at dawn or dusk, stay close to groups, and avoid wearing shiny objects that could attract sharks.
Still, the researchers believe this innovation marks a new era in marine safety — one defined not by fear of sharks, but by adaptation and respect for their role in the ocean.
“We can’t make the ocean risk-free,” Huveneers said, “but we can make it safer. And we can do it without harming the creatures that belong there.”
As the sun set over South Australia after the team’s final test, the ocean appeared unchanged — vast, silent, and untamed. Yet beneath its surface, something had shifted. The same species that once symbolized fear might now inspire balance — a coexistence born not from control, but from understanding.
The new shark-resistant wetsuit will not end attacks. But it might ensure that when the next encounter happens, a surfer, diver, or rescuer will have a fighting chance — not against the shark, but against time itself. (Wage Erlangga)
