The vaquita is the world's most critically endangered marine mammal with fewer than 20 individuals remaining. Its imminent extinction from bycatch in illegal gillnets represents a profound welfare and conservation failure.
The vaquita situation combines profound welfare concern for the remaining individuals with the imminent loss of an entire species. Each remaining individual carries enormous conservation weight — their deaths are not just individual welfare harms but species-level catastrophes. Gillnet entanglement causes drowning — a distressing, frightening death for air-breathing animals. The failure of conservation interventions — despite awareness, funding, and political will — reflects the difficulty of enforcing fishing restrictions against organised criminal networks motivated by totoaba bladder prices approaching $50,000 per kilogram. The capture attempt in 2017 demonstrated that even well-intentioned rescue efforts can cause fatal stress in this species. The remaining vaquitas represent one of conservation's most urgent remaining crises.
