The vaquita, an elusive porpoise that lives off the coast of Mexico, is the world's most endangered cetacean. New studies suggest that fewer than 100 of these creatures exist in the wild, and if enforcement measures aren't stepped up, the marine mammals could be extinct in four years.

Cute faces
Vaquitas are the smallest porpoises, and measure just 4 to 5 feet (1.2 to 1.5 meters) in length. The rare creatures live in the Gulf of California, off the coast of Mexico. The species diverged from their porpoise cousins between 2 million and 3 million years ago, and are most closely related to Burmeister's porpoises, which live off the coast of South America. They have winsome, almost smiling faces, with eyes and mouths fringed with black, as if they are wearing mascara and lipstick. (Photo credit: Alejandro Robles)
The diminutive porpoises are incredibly shy and are rarely seen in the water. Most of the time, they are spotted when they turn up dead in a fisherman's net. (Photo credit: Tom Jefferson)
Decimated population
The population has been decimated in recent years, and the culprit is the unchecked use of gill nets to fish for totoaba, an endangered fish prized in China for its swim bladder. Gill nets are a kind of vertical netting that act like a wall in the water, and because the vaquitas can't see them, they get entangled and die. (Photo credit: Proyecto Vaquita)

Illegal and legal fishing
A July 2014 report found that just 100 of the vaquitas exist in the wild, and that the population had declined by 18.5 percent over the past year. If fishermen dont' stop using gillnets in the vaquita habitat and the decline continues unchecked, the creature could be extinct in the next four years. (Photo credit: CIRVA)
Flagrant violation
Currently, only about one-fifth of the vaquita's habitat is a protected area shielded from gillnet fishing. But pictures released in December revealed over 90 fishing vessels in that protected area, and 17 of those boats had gillnets. (Photo credit: Google Earth, via IUCN)
Stepped-up enforcement
The main hope for saving the vaquita is to make gill net fishing illegal in all of the vaquita's habitat, increase the number of boats patroling for illegal fishing, and make it ilelgal ot even have a gill net on baord when fishing in the protected waters, said Rebecca Lent, the executive director of the Marine Mammal Commission.
