SAN FRANCISCO — A boat of salmon fishermen unexpectedly snagged a rare green sea turtle while fishing for salmon outside the Golden Gate Bridge.

The San Francisco Chronicle reported Saturday that the turtle is usually found off the shores of Mexico and the Galapagos island. A fisherman aboard the Sausalito, California-based Lusty Lady snagged the 150 pound turtle on Sept. 6. After determining the turtle was unharmed, removing the hook and snapping a few photographs, the crew tossed the turtle back into the ocean.

The photos were sent to scientists at the Turtle Island Restoration Network in Marin County. The scientists identified it as the endangered green sea turtle and speculated that it was a young adult male or female.

The water temperature in the area is five degrees warmer than normal.
