You’ve probably heard of the Giant Panda or the Black Rhino. Those are the poster children for conservation, right? But there is a tiny, shy porpoise living in a very small corner of the Gulf of California that makes a Panda look like a common pigeon in terms of population density. It’s called the Vaquita.
There are likely fewer than 10 of them left.
Let that sink in for a second. Ten. You could fit the entire remaining species in a single passenger van and still have room for groceries. This isn't just "endangered" in the way we usually think about it; this is a species standing on the absolute precipice of non-existence. Honestly, by the time you finish reading this, the math might have even shifted. It’s that dire.
What is a Vaquita, exactly?
The Vaquita (Phocoena sinus) is the smallest cetacean on Earth. It’s basically a miniature porpoise, barely five feet long, with these incredibly distinct dark rings around its eyes and patches on its lips. It looks like it’s wearing permanent goth eyeliner. They are incredibly elusive. Unlike dolphins, which might follow your boat or jump through wakes, Vaquitas are famously "boat shy." They surface for air with a tiny, quick puff and then vanish back into the murky, nutrient-rich waters of the Upper Gulf of California, the only place on the entire planet they call home.
Scientists didn't even formally describe them until 1958. We’ve known they existed for less than seventy years, and we are already watching the final curtain call.
The Totuaba Connection: Why they are dying
People often think Vaquitas are being hunted. They aren't. Nobody actually wants to kill a Vaquita. There’s no market for their meat, and they aren't aggressive. They are "bycatch." This is the cold, clinical term for animals that get caught in fishing nets intended for something else.
In this case, the "something else" is the Totoaba fish.
The Totoaba is another endangered species in the same waters, but it has a price tag on its head that would make a drug smuggler blush. Its swim bladder is highly prized in traditional Chinese medicine and as a status symbol. On the black market, a single Totoaba bladder can fetch tens of thousands of dollars. It’s literally referred to as "aquatic cocaine."
Illegal fishermen use gillnets to catch Totoaba. These nets are invisible walls of mesh that hang in the water. A Vaquita swims into one, gets its pectoral fins tangled, and because it’s a mammal that needs to breathe air, it drowns. It’s a fast, violent end for a creature that was just trying to find some squid or croaker for dinner.
The failed rescue missions
There have been desperate attempts to save them. Back in 2017, a massive international team of scientists, veterinarians, and even US Navy dolphins tried a project called VaquitaCPR. The idea was to capture the remaining porpoises and keep them in a protected sea pen until the gillnet problem was solved.
It was a disaster.

The first Vaquita they caught was a juvenile that became incredibly stressed and had to be released. The second was an adult female that died from cardiac arrest shortly after capture. The experts realized right then and there: Vaquitas cannot handle captivity. They are too high-strung, too sensitive. The mission was called off. Since then, the only strategy has been "in-situ" conservation—trying to protect them in their actual habitat.
Why haven't we just banned the nets?
Well, we did. The Mexican government banned gillnets in the Vaquita’s range. They even created a "Zero Tolerance Area" (ZTA). But reality is messier than a piece of paper signed in a government office.
The Upper Gulf is a place where poverty meets organized crime. When a fisherman can make a year's salary in a single night by catching Totoaba, a ban isn't much of a deterrent. Cartels have moved into the Totoaba trade because the profit margins are higher than drugs and the risk of jail time is lower.
Groups like Sea Shepherd and the Mexican Navy patrol the waters to pull up illegal nets. It’s a literal war zone out there. There have been riots in fishing towns like San Felipe. Drones have been shot down. Boats have been rammed. It's a complex socio-economic nightmare where the Vaquita is just collateral damage.
The genetic glimmer of hope
You’d think that with only 10 animals left, the species is doomed anyway because of inbreeding. Usually, that’s true. When a population gets that small, "bad" mutations start to pile up and the species loses the ability to reproduce or fight off disease.
However, a study published in the journal Science by researchers like Jacqueline Robinson and Barbara Taylor found something surprising. Because the Vaquita population has naturally been small for hundreds of thousands of years, they’ve already "purged" many of the harmful genetic variants that usually kill off small populations.
Basically, if we stop killing them in nets today, they are genetically healthy enough to bounce back. They aren't "doomed by their DNA." They are only doomed by us.
What it means for the ecosystem
Losing the Vaquita isn't just about losing a cute face. They are top predators in their specific niche. When you yank a predator out of a food web, everything else starts to tilt. We don't fully know what happens to the Gulf of California without them, but history tells us that "trophic cascades" usually end poorly for the fish humans actually like to eat.
How to actually help (The real list)
Most people just share a post on Instagram and feel like they did something. If you actually want to influence the fate of the rarest animal on Earth, it requires a bit more friction.
- Check your shrimp source. Most of the illegal fishing in the Gulf is masked by legal shrimp fishing. If you buy "Product of Mexico" shrimp without knowing the specific fishery, you might be indirectly funding the gear that kills Vaquitas. Look for "Fair Trade" or "Seafood Watch" approved sources that use "Vaquita-safe" trawl nets.
- Support the boots on the ground. Organizations like Sea Shepherd and the Museo de la Ballena are the ones physically pulling nets out of the water. They need funding for fuel, crew, and surveillance tech.
- Pressure for economic alternatives. The fishermen in the Upper Gulf need a way to feed their families that doesn't involve Totoaba. Supporting initiatives that help local communities transition to sustainable aquaculture or eco-tourism is the only long-term fix.
- Awareness of the Totoaba trade. If you live in or travel to regions where traditional medicine markets are common, be vocal. The demand drives the supply. Without the demand for "aquatic cocaine," the nets would vanish tomorrow.
The Vaquita is still here. For now. Every year that the survey ships go out and find a mother with a calf, it's a miracle. It proves they are still fighting. The question is whether we are willing to fight just as hard to keep the nets out of their way.
The next time you hear about a species being "rare," remember the Vaquita. It’s the ultimate test of whether humanity can stop a preventable extinction when the numbers are down to single digits. We missed the boat with the Yangtze River Dolphin (Baiji). We have one last chance to not repeat that mistake in the Gulf of California.
Keep an eye on the reports from the International Committee for the Recovery of the Vaquita (CIRVA). They are the ones doing the hard counting. Their data is the pulse of a species that is barely beating, but beating nonetheless.
