Do sea stars sleep in rocks?

My son asked me a really interesting question today that I couldn't answer. Do sea stars sleep in rocks? I tried searching online but didn't find a clear answer.

They don't actually sleep like we do, but they do hide under rocks to rest and protect themselves from predators and dry heat. It's like finding a safe spot to conserve energy, similar to how we need proper nutrition and rest to keep our energy levels up.

They don't have a brain, so actual sleep doesn't happen. They just have periods of inactivity under rocks. Don't believe everything you see in cartoon shows or random internet blogs about underwater animal behavior.

Look, they don't sleep with eyes closed under a blanket. They just hide in rock crevices during the day or when the tide is low so they don't get dried up by the sun. It's simple survival, nothing fancy.

They hide under rocks to survive. If you are exploring rocky beaches to find them and happen to scrape your hand or foot, please get it treated immediately. I once ignored a minor scratch on a wet rock and ended up with a severe fungal infection that took months of clinic visits to cure.

Yes, sea stars often seek shelter under rocks or in crevices to rest and hide from predators. While they don't have a sleep state like mammals, they have inactive periods. It's a very natural way for them to stay safe and hydrated.
