What’s blue, 80 feet long, weighs about 100 tons and is missing? A Southern California whale entangled in a fishing line.

Aircraft joined wildlife rescuers Saturday in the search for the slippery mammal in the waters off Catalina Island, the Los Angeles Times reported.

The whale, first seen from a cruise ship off Rancho Palos Verdes, was last spotted Friday in the channel between LA and Catalina Island, Jim Milbury, a spokesman for the National Oceanic and Atmospheric Administration, told Reuters.

The NOAA alerted whale-watching and recreational boats to look for the whale and asked them to notify the Coast Guard or the NOAA if they saw it, Milbury said.
