The vaquita is the world's most critically endangered marine mammal, with fewer than 10 individuals remaining. Its imminent extinction from gillnet bycatch in the Gulf of California represents one of the most urgent and tragic wildlife welfare crises on Earth.
Every remaining vaquita represents an individual animal whose welfare is under continuous threat from entanglement risk. Animals that die in gillnets experience drowning — a prolonged, distressing death by asphyxiation. The attempt to rescue the species through captive breeding caused acute welfare harm to the animals captured, demonstrating that even conservation interventions can impose severe suffering on individuals. The vaquita's situation illustrates the catastrophic endpoint of inadequate enforcement of wildlife protection in the face of extreme economic incentives for illegal fishing. Preventing extinction requires urgent international cooperation on both supply reduction in Mexico and demand reduction in Chinese consumer markets.
