The vaquita is the most critically endangered marine mammal, with fewer than 10 individuals remaining in the northern Gulf of Mexico, facing extinction primarily from gill net bycatch.
The vaquita extinction crisis is unfolding in real time, with individual animals dying in gill nets set for a fish whose swim bladder fuels an illegal trade. Each vaquita death brings the species closer to a point of no return from which no conservation intervention can recover. The welfare dimension is stark — these are individual animals with complex lives who die drowning in nets set for a different species entirely. The failure to enforce gill net bans in vaquita habitat despite international pressure and biological urgency represents a regulatory failure with irreversible consequences. Every individual vaquita life now represents an irreplaceable fraction of the species survival.
