A blue whale that is believed to be tangled in fishing line may be in Mexican waters, authorities said Monday.

The 80-foot mammal was last seen Friday between Los Angeles Harbor and Catalina Island. It was trailing about 400 feet of line with a 3-foot buoy attached.

The whale was spotted at 10:30 a.m. Monday, about 19 miles southwest of the southernmost Coronado Islands, which are about 19 miles south of San Diego.
