New Bite-Resistant Wetsuits Reduce Shark Bite Injuries

Australian researchers have developed a new generation of bite-resistant wetsuits that can reduce the severity of shark bite injuries, offering greater safety for surfers, divers, and swimmers in shark-prone waters.

Although fatal shark attacks are extremely rare, sightings of large sharks have increased in several regions, heightening public concern. In 2024, fewer than 50 unprovoked shark bites on humans were recorded worldwide, according to the International Shark Attack File.

The study, led by scientists from Flinders University in Adelaide, tested four advanced materials—Aqua Armour, Shark Stop, ActionTX-S, and Brewster—by exposing them to white and tiger sharks in real ocean conditions. Results, published in Wildlife Research, showed that all four outperformed standard neoprene wetsuits in reducing damage.

“Bite-resistant materials do not prevent shark bites, but they can lessen injuries and provide added protection,” said Professor Charlie Huveneers of Flinders University’s Southern Shark Ecology Group.

Researcher Tom Clarke added that the new suits significantly reduced damage associated with severe bleeding, tissue loss, and potential limb loss.

Unlike rigid chainmail suits, which have long been used for shark resistance but lack flexibility, these new wetsuits balance both mobility and protection—making them more practical for water sports.

However, the researchers cautioned that the suits cannot eliminate risks entirely. Large sharks may still cause internal trauma or crushing injuries, and basic safety measures remain essential in shark habitats.

Marine scientists welcomed the development. “This doesn’t rely on changing shark behaviour,” said Nick Whitney, a senior scientist at the New England Aquarium in Boston. “In the rare event of a bite, these wetsuits may help you bleed less than with a normal suit.”

While not foolproof, the innovation represents an important step forward. “We hope this research helps people make informed decisions about the suitability of these products,” Huveneers said.
