The Paghman stream salamander or the Afghani brook salamander (Paradactylodon mustersi) is a salamander endemic to Afghanistan. It inhabits cool highland streams. The total population is estimated at 1,000–2,000 adults. It is only found in an area of 10 km2. 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. Currently, it can only be found in cold water: it has only been found in water ranging from 0 to 14°C.
