Los Angeles County officials said a homeowners' association hired a tugboat on Saturday to tow the dead whale about 20 miles away from shore.
The 40,000-pound whale washed ashore on Monday near Point Dume, the apparent victim of a boat collision. But after no government agency stepped forward to take charge of its removal, a group of neighbors took care of it.
The whale drew a steady stream of visitors, some snapping photos, others bagging souvenirs.
Fin whales are endangered, and about 2,300 live along the West Coast. They're the second-largest species of whale after blue whales and can grow up to 85 feet, weigh up to 80 tons and live to be 90 years old.
