What is the Vaquita?
The vaquita is a small porpoise found only in the northern Gulf of California (Sea of Cortez) in Mexico. Only 30 of these animals remain, making the vaquita the most endangered marine mammal in the world.
What is the vaquita?
The vaquita (Phocoena sinus) is the world's smallest cetacean. Its name means "little cow" in Spanish. A dark ring around the eyes is its most striking feature, along with a proportionally large dorsal fin. The vaquita is unique among the porpoises as it is the only species of that family found in warm waters, and the size of the dorsal fin is believed to be an adaptation to that, allowing for extra body heat to dissipate. Vaquita only live in the northern Gulf of California, the Sea of Cortez, Mexico.
Like many other species of porpoise, vaquita tend to be shy and elusive, avoiding boats when approached. They are most commonly sighted in shallow waters up to 50 metres deep. And like their closest relative, the harbour porpoise, they tend to prefer turbid, nutrient-rich coastal waters which attract their preferred prey: small fish, cephalopods and crustaceans.
What are Porpoises?
Porpoises are among the smallest members of the cetacean family (whales, porpoises and dolphins). They are only distant relatives of dolphins (they last had a common ancestor roughly 15 million years ago). There are only seven species of porpoise; the most popular being the widely distributed harbour porpoise.
Many species, including the vaquita, are barely studied. Most of what we know about them comes from examining animals that have been washed ashore.
Where do Vaquita live?
Why is the Vaquita endangered?
The vaquita population has been in sharp decline for decades, recently accelerated by illegal fishing with gill-nets for the endangered totoaba, a large fish sought after for its swim bladder.
Gill-nets: The Invisible Killer
The single most significant threat to the vaquita's survival is accidental entanglement. The small animal frequently gets caught in fixed fishing nets (gill-nets), as by-catch. Unable to surface for air, the entangled animals drown within minutes. This threat is accelerated by illegal fishing for another endangered species that lives in the vaquita habitat, the totoaba ─ a large species of fish sought after for its swim bladder, driven by demand from China where it is considered a delicacy with medicinal value.
Gill-nets are particularly dangerous because they are indiscriminate. While usually designed for a single species, large amounts of unwanted by-catch are inevitable. More than 300,000 whales, porpoises and dolphins get entangled in fishing nets annually. Most of them die, and the few that get away do so with severe injuries.
Ban on Gill-net Fishing in the Sea of Cortez
In April 2015, the Mexican government announced a two-year ban on gill-net fishing in the vaquita habitat, to be enforced by the Mexican navy. Conservation organizations welcomed the initiative, but stressed that unless the ban was made permanent, the measure did not go far enough. In July 2016, a permanent ban was finally announced, together with a ban on night fishing to aid the fight against poachers. However, it is illegal fishing that is responsible for the vaquita's dramatic decline, and that is unlikely to stop immediately.
It is now up to Mexico to enforce the ban, and for the international community to curb the market for totoaba swim bladders in China and to go after poachers. The fight to save the vaquita continues.
The Solution: End Gill-net Fishing Forever
There is nothing else we need to worry about other than gill-nets. If we remove the gill-nets, we will likely save the vaquita.Dr. Anna Hall, Porpoise Conservation Society
How can I help save the Vaquita?
The window of opportunity for saving the vaquita is closing fast, but extinction is still preventable. You can help by making the right choices at the supermarket, by donating to conservation efforts, or simply by spreading the word.
Join our Mission
Support our efforts to raise awareness and save the critically endangered vaquita porpoise from extinction with a symbolic adoption, for yourself or as a gift.
Spread the Word
The vaquita needs all the attention it can get. Support the conservation effort by spreading its story. Raise awareness by telling your friends and family about the vaquita porpoise.
Buy Sustainable Seafood
Entanglement in fishing nets is what is driving this species to extinction. You can help by making sustainable choices when buying seafood. There are programs to help you make that choice.
Support the Region
Support the region by providing an alternative to gill-net fishing. Spending your tourism dollars in the beautiful Baja California region is a great way to support the local economy.
Why is it so important that we fight to save the Vaquita?
The vaquita is not the only marine mammal in trouble, nor would it be the first of the whale and dolphin family to go extinct in recent years. The Baiji, or Yangtze River dolphin, was declared functionally extinct in 2006 when a survey mission failed to find a single individual in the Chinese waters it called home. Conservation efforts for this species that began in the 1970s had failed.
We must not allow for a second species of cetacean to become extinct in our lifetime. The vaquita is a unique animal, and an important predator. We do not know what consequences its disappearance would have for the entire ecosystem. Its decline is man-made and its extinction entirely preventable.
Let Mexico know you support the vaquita!
Mexico has done a few things help the vaquita, but none of it has been effective. It needs to intensify its enforcement efforts. Send a message to the Mexican President, commend him for his efforts to save the vaquita and encourage the Mexican government to keep up its efforts to remove gill-nets from the vaquita habitat forever and to step up enforcement before the last vaquita have vanished.
