French officials to use orcas sounds to guide lost killer whale back to sea

A plan has been hatched to guide a killer whale adrift in France's River Seine back to the sea — using orca sounds, local officials said on Friday. Following a meeting with national and international scientists, including marine mammal specialists, the local prefecture said it would monitor the killer whale from a distance with a drone while emitting orca communications in an attempt to guide it back to the sea.
