Hammerhead sharks are among the most threatened shark species due to fin trade demand, with their unique sensory anatomy making their welfare in captivity and during finning particularly significant.
The practice of shark finning — removing fins at sea and discarding the body — causes death through drowning or bleeding from animals that are conscious throughout. Even when sharks are brought to shore whole, poor handling and inadequate slaughter practice means many sharks die in distress. Hammerheads are particularly poorly suited to captivity, typically dying within days from stress and inability to meet their sensory and movement needs in tank environments. Their social aggregation behavior means that population depletion affects not just individual survival but the social context that remaining animals depend on. Consumer choices to avoid shark fin products directly reduce demand that drives this welfare catastrophe.
