Most people might guess that the most endangered marine mammal would be the blue whale, or perhaps the narwhal, or other well-known endangered species. But, in fact the most endangered marine mammal on Earth is a small Mexican porpoise people might not even know existed — the vaquita (meaning “little cow” in Spanish). Vaquita sightings are very rare. Scientists believe there are only a few dozen of them left in the world, and challenges they face threaten to make them disappear altogether.

Vaquita were discovered in the late 1950s and can be found only in the upper Gulf of California in northern Mexico just south of the United States border. There has been a steep reduction in the species’ numbers, from about 550 vaquitas in 1997 to just 60 in 2015 — a 92 per cent drop in less than 20 years. These small porpoises are on the brink of extinction; their single biggest threat is gillnet fishing.

Join us on July 8 as we raise awareness for the critically endangered vaquita.

Vaquita get caught in gillnets used to target commercially valuable species of fish and are being decimated. In 2016, the government of Mexico declared a permanent ban on the use of gillnets in vaquita habitat areas, but illegal poaching continues. Without further protection, it is reasonable to expect that this porpoise will go extinct during the course of our lifetime.

Fortunately, conservation scientists around the world are working together to raise awareness about the vaquita, and the second Saturday of July has been declared International Save the Vaquita Day. Join us on July 8 as we raise awareness for the critically endangered vaquita. The Porpoise Conservation Society will be co-hosting a whole day of vaquita programming with the Vancouver Aquarium to highlight the plight of this species, of which less than 30 animals remain in its native Mexico.

Scientists believe there are only a few dozen vaquita left in the world.

You can watch Dr. Hall’s talk from 2016’s Save the Vaquita Day event here.

The plight of the remaining vaquita is dire, but it is not too late to prevent the extinction of these unique porpoises. The Vancouver Aquarium is proud to join the call to action in order to protect this species for future generations. Vaquita are not the only marine animals threatened by unsustainable fishing practices —remember to look for the Vancouver Aquarium Ocean Wise symbol next to seafood items to make ocean-friendly seafood choices.
