Mexican fishermen attack Sea Shepherd vessel protecting vaquita porpoise

• Two dozen boats douse conversation vessel with gasoline
• As few as 15 vaquita may remain in Gulf of California

The Sea Shepherd environmental group has published video showing an attack by about two dozen small fishing boats on the group's vessel Farley Mowat in Mexico's Gulf of California.

The fishermen in the Gulf, also known as the Sea of Cortez, oppose environmentalists trying to protect the vaquita marina, the world's smallest and most endangered porpoise.
