Australian scientists have tested bite-resistant wetsuits by letting sharks bite them at sea. The study shows these suits can help keep swimmers safe. While fatal shark bites are rare, increased shark sightings have people looking for protection. Researchers at Flinders University tested four materials and found they all reduced damage from shark bites. The materials don't prevent bites but can lessen injuries compared to standard wetsuits. Newer designs offer flexibility for activities like surfing and diving. Experts say these suits are promising for those in shark-prone areas but caution is still needed.
