Vaquita, the world’s most rare marine mammal, is on the edge of extinction. This little porpoise wasn't discovered until 1958 and a little over half a century later, we are on the brink of losing them forever. Vaquita are often caught and drowned in gillnets used by illegal fishing operations in marine protected areas within Mexico's Gulf of California. More than half of the population has been lost in the last three years.

The vaquita has a large dark ring around its eyes and dark patches on its lips that form a thin line from the mouth to the pectoral fins. Its dorsal surface is dark gray, sides pale gray and ventral surface white with long, light gray markings. Newborn vaquita have darker coloration and a wide gray fringe of color that runs from the head to the dorsal flukes, passing through the dorsal and pectoral fins. They are most often found close to shore in the Gulf's shallow waters, although they quickly swim away if a boat approaches.

 

15 WWF Success Stories of 2013

As 2013 comes to a close, WWF takes a look back at successes over the past 12 months.

Why They Matter

  • The vaquita is the most endangered cetacean in the world. With likely fewer than 100 left, the species will become extinct without a fully enforced gillnet ban throughout their entire range. WWF urgently working to ensure they can live and thrive in their natural habitat.

Threats

  • Population Fewer than 100 individuals
  • Extinction Risk Critically Endangered
    1. EX
      Extinct

      No reasonable doubt that the last individual has died

    2. EW
      Extinct in the Wild

      Known only to survive in cultivation, in captivity or as a naturalised population

    3. CR
      Critically Endangered

      Facing an extremely high risk of extinction in the Wild

    4. EN
      Endangered

      Facing a high risk of extinction in the Wild

    5. VU
      Vulnerable

      Facing a high risk of extinction in the Wild

    6. NT
      Near Threatened

      Likely to qualify for a threatened category in the near future

    7. LC
      Least Concern

      Does not qualify for Critically Endangered, Endangered, Vulnerable, or Near Threatened

The vaquita will be extinct, possibly by 2018, if fishery bycatch is not eliminated immediately. Nearly one out of every five vaquita get entangled and drown in gillnets intended for other marine species like the totoaba, a critically endangered fish also found in the upper Gulf of California. Entanglement in gillnets set for totoaba was the primary cause that brought the vaquita to low levels by the mid-1970s. Totoaba were overfished by the mid-1970s and were listed as endangered by Mexico in 1975, and by the US in 1979.

Today, international trade in totoaba is banned under CITES but high demand from China for its swim bladder has led to a corresponding boom in illegal totoaba fishing in the past few years. Thousands of swim bladders are dried and smuggled out of Mexico, often through the United States. Fishermen receive around $4,000 for each pound of totoaba swim bladder, equivalent to half a year’s income from legal fishing activities. It is this illegal trade that is currently driving the precipitous decline in vaquita numbers.

What WWF Is Doing

Fin

WWF is on red alert after a recent report from the International Committee for the Recovery of the Vaquita (CIRVA) estimated the vaquita population at less than 100. In the past, WWF has helped study vaquitas and implement protective measures with the Mexican government and local partners. We have been working with Mexican scientists, government representatives, and other partners and collaborators to develop a long-term strategy for conservation of the species.

We are now calling for urgent and immediate measures to save the last of the vaquitas.

Based on expert recommendations, WWF calls on the Mexican government to strongly enforce a ban on gillnet fisheries throughout the entire range of the species starting in September 2014. We also ask that the US and China help stamp out the illegal trade in totoaba products and provide enforcement support to the Mexican government, without which vaquitas will go the way of the dodo.
