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?
