Some marine snails make use of gills while many make use of lungs for breathing, and so, can breath air which they sometimes trap in their shell in order to help them float.

Their breathing system is located in a small cavity between their shells and their bodies. Air goes into this cavity through a small opening or pore on the side of the snail’s body,

Sometimes you could see your Aquarium snails float to the surface of the water because they make use of air to do that.

So, after trapping the air to breathe and float, they need to expel it because it can’t stay forever in their body, so that’s why they make bubbles.
