Shark bites on humans are rare but can have substantial consequences for local coastal communities and businesses, often prompting pressure to implement effective mitigation measures. Wetsuits that incorporate bite-resistant materials have emerged as a new mitigation strategy that aims to reduce fatalities from shark bites, by reducing the severity of injuries inflicted from bites (e.g. lacerations, punctures, tissue and blood loss)

[…]

Key results

All bite-resistant materials reduced the proportional area of bites in substantial and critical damage categories, the categories associated with haemorrhaging and major vascular injury. However, there were limited to no differences in substantial and critical damage categories across the bite-resistant materials. Shark length also influenced the proportion of damage from tiger shark bites, but not from white shark bites.

Conclusions

Although internal and crushing injuries might still occur, bite-resistant materials offer an improved level of protection that can reduce severe wounds and blood loss, and should be considered as part of the toolbox and measures available to reduce shark-bite risk and resulting injuries.
