Wild Vaquita Porpoise: The World's Most Endangered Marine Mammal

The vaquita is the world's rarest marine mammal, with fewer than 10 individuals remaining. Its story is one of the most urgent conservation and welfare crises in history.

Key Facts

The vaquita (Phocoena sinus) is a small porpoise endemic to the northern Gulf of California, Mexico — its range is the smallest of any cetacean species
Population estimates have plummeted catastrophically: from approximately 600 in 1997 to fewer than 10 in 2024 — the fastest decline of any marine mammal in recorded history
The primary cause of decline is incidental entanglement in gillnets set for the totoaba fish (Totoaba macdonaldi), whose swim bladder is illegally trafficked to China for traditional medicine
Vaquitas drown in gillnets — a slow, terrifying death by asphyxiation for an air-breathing mammal unable to surface
Despite gillnet bans and enforcement efforts in the upper Gulf of California, illegal fishing continues due to the extreme value of totoaba swim bladders (sometimes called "aquatic cocaine")
A 2017 emergency capture attempt to hold vaquitas in protective custody failed when the first captured female died of capture-related stress, leading to the programme's termination
Without elimination of illegal gillnet fishing in the vaquita's range, extinction is considered virtually inevitable
The totoaba itself is also critically endangered — both species are collateral damage of a demand-driven trafficking crisis

Welfare Considerations

The vaquita welfare crisis is acute and individual: each of the remaining animals faces daily risk of entanglement death in illegal gillnets. Drowning in a net — unable to surface to breathe — is one of the most distressing deaths possible for a cetacean. The failed capture attempt demonstrated that vaquitas are so sensitive to human contact that even well-intentioned intervention can be fatal. The remaining individuals exist in a state of profound isolation — a species reduced to the minimum viable population threshold that carries its own ecological trauma. The welfare solution requires eliminating demand for totoaba swim bladders in China through education and enforcement, and ensuring effective enforcement of the gillnet ban in the upper Gulf of California. Every individual vaquita death is both a conservation catastrophe and an individual welfare tragedy.

What You Can Do

Support organisations fighting totoaba trafficking: Environmental Investigation Agency (EIA), Sea Shepherd Conservation Society, and CEDO Intercultural
Never purchase products that may contain totoaba or vaquita derivatives
Advocate for stronger US-Mexico-China trilateral cooperation on totoaba trafficking enforcement
Support Mexican fishing communities in transitioning to vaquita-safe fishing gear as an economic alternative to illegal gillnetting
Raise awareness about the vaquita crisis — many people have never heard of this animal despite its imminent extinction
