Tarahumara salamander
The Tarahumara salamander (''Ambystoma rosaceum'') is a freshwater species of mole salamander in the Ambystomatidae family, endemic to Mexico.
Its natural habitats are temperate forests, subtropical or tropical moist montane forests, subtropical or tropical high-altitude grassland, rivers, freshwater marshes, pastureland, and ponds.
The Tarhumara salamander may actually be two different species separated by the Sierra Madre Occidentental in northwestern Mexico. It's classified as Least Concern, but habitat loss, introduced predatory fish, and increasing agriculture in the area pose threats to its survival. The Government of Mexico classifies it as Pr, meaning Special Protection.
==Description==
The Tarhumara salamander is a medium-sized salamander with a maximum snout to vent length of about and a tail of about . Females have longer bodies and shorter tails than males. Newly-hatched larvae are a uniform brownish-black, older larvae have rows of yellow and black mottling and most terrestrial adults have large spots or streaks of yellow on a dark background, though some are plain. Some individuals are paedomorphic and do not pass through metamorphosis to the terrestrial adult state but remain as aquatic, gilled paedomorphs. This happens most often in montane streams and ponds.
