      @Hannah Yes they do, but with their eyes open because they have no eye-lids. Also, they sleep in a state of alertness so that they can respond to danger. Their activity and metabolism go down in these “sleep” periods, but they get out of it pretty quickly if a predator comes along.

      They do sleep! Some of them (I think it’s a parrotfish) make a spit-bubble around themselves when they sleep, which looks great.
