The Mexican volcanic mouse is a small rodent that lives on the slopes of volcanoes in central Mexico. It is active at night and well adapted to life at high altitudes.
The Mexican volcanic mouse stands out for living at high altitudes near volcanoes, where there are few other rodents. It is important for nature as a seed disperser for plants and food for snakes, birds, and foxes.
