So I am watching this small snail hoovering along the bottom of a tidal pool, and every so often the water level would drop and expose him to the air for a while. Then the water level would rise and he would be covered up with water again.
Was he like taking big deep breaths before going under again? Or was he breathing under water and holding his breath when exposed to air?
Do snails have noses or gills? I have been wondering this all day...
