The pneumostome or breathing pore is a respiratory opening of the external body anatomy of an air-breathing 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.

| - The pneumostome or breathing pore is a respiratory opening of the external body anatomy of an air-breathing 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. The pneumostome is often much easier to see in slugs than in snails, because of the absence of a shell which can often block the view of this area. In a land slug, when the pneumostome is wide open, it is usually very clearly visible on the right side of the animal. However, the position of the pneumostome is often not at all easy to discern when this orifice is completely closed. The pneumostome opens and closes in a cyclical manner. The frequency of pneumostome closing and opening is typically less than 0.5 closures per minute in fully hydrated slugs and snails. The rate of closures per minute increases the more dehydrated the slug is. (en)

Pneumostomet är väl synligt hos sniglar, men kan vara svårt att upptäcka hos snäckor, främst på grund av skalet. Poren sitter oftast på djurets högra sida, men sitter hos vissa arter mitt på ryggen. Hos sniglarna sitter den på (ryggskölden) och placeringen av poren kan hjälpa till vid artbestämning. Organet finns främst på landlevande sniglar och snäckor, men Physidae, Planorbidae och Lymnaeidae använder pneumostomet som komplement till sin syreupptagning genom huden vid låga syrenivårer i vattnet. För att minimera vätskeförlust och förhindra uttorkning hålls pneumostomet stängt så mycket det går vid torra förhållanden. En undersökning på arten visade att snigeln börjar stänga poren med tätare mellanrum vid en vätskeförlust på 15–20 % av kroppsvikten. (sv)
