EDGE Analysis

The Michoacan stream salamander exhibits some highly unusual and distinct features, indicative of its evolutionary distinctiveness. Based on studies of its DNA and proteins, it is thought to be one of the most distinct species of Mexican mole salamander. This is a fairly large species of salamander, reaching a total length of around 170 mm, with a tail that measures about 75 mm. Most individuals do not metamorphose, but local people report that some do leave their watery habitats for a life in a different form on the land. The species may be threatened by the pollution and desiccation of its breeding streams, which is resulting from current water extraction activities.
