    Don’t they usually fall asleep underwater with only their snout sticking out of the ice?

      That does happen but I don’t believe they are intentionally doing that. I think they just slow down and keep their nose out the water to breathe and the water freezes around them or they break through the ice to breathe and the water refreezes.
