According to the Pacific Marine Mammal Center, it was an older 40-foot whale that was towing approximately 50-100 feet of line on its left pectoral fin.
"They successfully attached three buoys to the animal. They have not yet gotten in an ideal position to start cutting away that line," said Melissa Sciacca of the Pacific Marine Mammal Center.
The crew also found that there was more fishing line entangled in the whale's mouth.
"We had a 40- to 45-foot whale let us know in no uncertain terms that it did not like what we were trying to do for it," said Dana Friedman, one of the rescuers.
Rescuers were able to free a portion of the line, but had to suspend the operation for the night. They will resume Wednesday morning. Three large bright buoys are marking the whale's location. They determined the whale was in good health.
