thumb|Arion vulgaris opening its pneumostome thumb| An individual Arion rufus with the pneumostome wide open thumb|Drawing showing the different external anatomical features of a slug thumb|right|Open and closed pneumostome thumb|The pneumostome of Triboniophorus graeffei is on its dorsal surface. The pneumostome or breathing pore is a respiratory opening of the external body anatomy of a pulmonate land slug or land snail. It is a part of the respiratory system of gastropods.
It is an opening in the right side of the mantle of a stylommatophoran snail or slug. Air enters through the pneumostome into the animal's single lung, the air-filled mantle cavity. Inside the mantle cavity the animal has a highly vascularized area of tissue that functions as a lung.
