Hammerhead Shark Conservation and Welfare

Hammerhead sharks face critical population declines from finning, bycatch, and habitat loss, with their distinctive morphology making them uniquely vulnerable to fishing mortality.

Key Facts

Three hammerhead species are listed as Critically Endangered on the IUCN Red List
Hammerheads are among the most common sharks landed in the global fin trade
Their large fins are prized for shark fin soup, driving targeted and bycatch mortality
Hammerheads are viviparous, with long gestation periods and small litter sizes limiting recovery
Their schooling behavior makes them highly vulnerable to encirclement by purse seine vessels
Research shows hammerheads experience significant physiological stress during capture

Welfare Considerations

Hammerhead sharks suffer acutely during capture and finning. Live-finning - removing fins while the animal is alive before returning it to the sea to drown - remains common in some fisheries and causes extreme suffering. Even capture and release in bycatch scenarios causes severe stress, injury from hooks or nets, and high post-release mortality. Their long recovery times mean population impacts accumulate over decades.

What You Can Do

Refuse shark fin products and advocate in your community against their consumption
Support hammerhead shark listing upgrades under CITES Appendix II and national laws
Back marine protected area designations that include key hammerhead habitats
Donate to research organizations studying hammerhead ecology and bycatch reduction
Choose seafood certified by programs with shark bycatch monitoring requirements
