Scientists find new bite-resistant wetsuits can reduce shark bite injuries
PORTLAND, Maine (AP) — Australian scientists tested the strength of bite-resistant wetsuits by allowing sharks to chomp the materials at sea and found that the suits can help keep swimmers safe.
Fatal shark bites are vanishingly rare, with less than 50 unprovoked shark bites on humans worldwide in 2024, according to the International Shark Attack File at the Florida Museum of Natural History. But increased sightings of large sharks in some parts of the world have swimmers, surfers and divers looking for new ways to stay safe.

Scientists with Flinders University in Adelaide, South Australia, tested four bite-resistant materials and found they all reduced the amount of damage from shark bites. They performed the work by dragging samples of the materials behind boats and allowing white and tiger sharks to bite the samples.
The bites from such large sharks can still cause internal and crushing injuries, but the materials showed effectiveness beyond a standard neoprene wetsuit, the scientists said. The research found that the bite-resistant materials “can reduce injuries sustained from shark encounters,” said Flinders professor Charlie Huveneers, a member of the Southern Shark Ecology Group at Flinders and a study co-author.
“Bite-resistant material do not prevent shark bites, but can reduce injuries from shark bites and can be worn by surfers and divers,” Huveneers said.
There were small differences between the four tested materials, but they all “reduced the amount of substantial and critical damage, which would typically be associated with severe hemorrhaging and tissue or limb loss,” said Tom Clarke, a researcher with the science and engineering college at Flinders and a study co-author.
