Oysters can hear noise

and it’s stressing them out! Jean-Charles Massabuau, a marine biologist at the French National Centre for Scientific Research, was working on a different project when a diver noted he had never dived in such a noisy spot. Massabuabu wondered if the oysters in that location could hear the noise. After setting up an experiment to see if they would react (they did!) and how (shutting their shells), Massabuabu and team wrote up their findings. Although the oysters had a way to shut out the noise, it comes at a price–they can neither eat nor breathe when their shells are closed.

There is a well-established body of research about ocean sound, but Massabuabu thinks his study results suggest “we should expand our concerns about the impact of noise pollution beyond today’s focus on only dolphins and whales.”

We agree.

Though we must add that while noise pollution may stress out oysters, it’s probably pales in comparison to waiting to be shucked and served with a side of cocktail sauce.
