Hole in a Slug

That's the pneumostome, it's like a big nostril. Thanks for showing us though, buddy.

Here we have an explanation on the "hole"The pneumostome (or breathing pore) is a feature (the 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.

Give him some room not everyone can be an expert in gastropods, you dig?

"See slug, get salt" has always been my motto. That is until my five year old decided he can't enough of anything creepy or crawly

I saw two slugs in my life, both times from afar. And I live in a rural area. Somehow.
