Dr. Dan KillamI 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
Dr Neenah Estrella-Luna@dantheclamman This is a deeper question than I think most are appreciating. Is the child asking whether they go into a state of inactive rest or is the child asking whether they dream. Those are different questions.
