Mexico seeks 'miracle' to save near-extinct vaquita porpoise

Mexico's navy and the environmental organization Sea Shepherd are working together to prevent the vaquita porpoise—which counts Leonardo DiCaprio among its celebrity defenders—disappearing forever.

The species is critically endangered, due to illegal gillnets used to catch totoaba, a large fish whose can fetch thousands of dollars in China thanks to its supposed medicinal properties.

The navy stepped up surveillance in January amid criticism from the United States that Mexico was not doing enough to protect the vaquita, the smallest porpoise on the planet.

The deployment came after researchers sighted eight specimens of the mammal—known as the "panda of the sea" for the distinctive black circles around its eyes—between October and November.

There are estimated to be fewer than 20 individuals left in a small area in the Gulf of California, the only place in the world where the vaquita is found, according to Sea Shepherd.

Navy personnel and activists from the conservation group now monitor the area every day, looking for illegal nets and preventing fishermen from approaching a "zero tolerance zone."
