Is it a breathing hole?

we have checked the link, does air hole mean the same as breathing hole?

Yes. Air hole and breathing hole are the same.

slugs have a breathing hole.it opens and closes as the slug travels along its moist slime.

Yes, you're correct! Slugs, like other terrestrial gastropods, breathe through a specialized structure called a "pneumostome," also known as a breathing hole. This opening works like a lung, allowing the slug to exchange gases with the environment.

If you're curious about how to find this information, one way to determine a slug's method of breathing is through research. You can search for reliable sources such as books, scientific articles, or reputable websites that provide information on slug anatomy and respiration. By referring to these resources, you can find the details on how slugs breathe and verify your answer.
