Los Angeles County lifeguards say a dead humpback whale has washed ashore at Dockweiler Beach.
The whale floated in just before 8 p.m. Thursday.
The whale is approximately 40 feet long and is believed to have been between 10 to 30 years old.
Marine animal authorities will try to determine why the animal died.
It's not the same whale that was spotted Monday off Southern California entangled in crab pot lines. The entangled animal is a blue whale.
