The population of Mexico's endangered vaquita marina, the world's smallest porpoise, has fallen to alarmingly low levels and is heading toward extinction soon if drastic measures aren't taken, scientists warned Friday.
According to results of a survey released in the evening by the country's Environment Department, as of December there were probably only about 60 of the shy, elusive creatures left in the upper Gulf of California, the only place where the vaquitas are found.
The vaquitas are threatened primarily by gillnet fishing for the totoaba fish, another endangered species in the area that is hunted . . .
