"Mexico Enlists Dolphins To Help Endangered Tiny Porpoise"

"Mexico's government has enlisted the help of three trained dolphins to locate in the wild their less fortunate cousin, the rare vaquita porpoise, in an effort to bring back from the brink of extinction a species with fewer than 40 specimens left.

Populations of the vaquita, a tiny snub-nosed porpoise that lives in the Gulf of California, have dropped sharply in recent years because of gillnet fishing for shrimp and totoaba, a popular delicacy in Asia, causing increased international concern and pressure on Mexico.

The three dolphins "will be released in September in the Gulf and they will help us locate where the vaquitas are," Mexico's environment minister, Rafael Pacchiano, said on Monday."
