This is one of two salamanders with the common name Michoacan Stream Salamander (the Puerto Hondo Stream Salamander,
A. ordinarium, is the other). It is a "mole salamander" spending some time in underground burrows but breeds in water.
It is native to a small area of streams, ponds and lakes in montane forest of central Mexico and is endangered.
The young are aquatic and can remain and reproduce in the larval form like several other Ambystoma species
but they also develop into terrestrial adults (as above).
