Beached whales
lundi 29 juin 2015 à 14:00A group of 39 whales beached themselves one day in 2011. Scientists now say they did this because underwater bomb explosions damaged their hearing and navigation.
19 of the whales died; the rest went back to sea. Perhaps their hearing was ok and they only followed the others; or perhaps they didn't live long.
Underwater explosions for oil drilling can do the same thing.
