I once was asked by a kindergartner if clams sleep. I was stumped, and we actually have no idea! We know many bivalves have strong biological clocks, often showing circadian rhythms in activity. But as to whether they sleep? No one knows! #clamFacts

A city monitors water quality with instrumented clams.
They might know?
Possibly Warsaw, or one in Czecho?

@Photo55 yes those valvometry studies are super cool! it is a whole field of work, including a study I did, and provides very useful data on their circadian cycles! as to whether those are sleep or just rest, other scientists are investigating the neurological signals of clams and other mollusks to try to get to the bottom of it!
