P. mustersi is known to reside in the Paghman Mountains in Afghanistan, where it lives in fast-running waters (the adults and the eggs or larvae in calmer, deeper water) which are formed from melting glaciers.

They may look similar to salamander species, but unlike many others, the Paghman stream salamander can feed in water, they are found under rocks in the fast running water, and even catch prey on land.

They are expected to be found in the southern slopes of the Hindu Kush near Afghanistan.

The more the land is being used by humans, the worse it gets for the Paghman stream salamander.

To remain a part of Afghanistan's ecosystem, its habitat needs to be conserved.
