nostrils
For the most part, frogs breathe air through the mouth, and utilize internal nares when doing so outside of the water. In the water, they can put just enough of the external nares above water, but this is more important to get rid of carbon dioxide, as frogs can diffuse oxygen from the water through their skin.
nares is what they are called for baby and adult frogs
The internal nostril openings (nares) carry air from the nostrils to the mouth, so that a frog can breathe air when on the surface, by expanding its mouth to pull in and "swallow" air. Underwater, the internal nares close to keep water out.
The frogs' nostrils are called external, as they are visible on the outside of the frog's snout. These nostrils allow the frog to breathe air when it is on land.
