The Mexican Alligator Lizard is a species of lizard that is native to the highlands of Mexico. This endangered species is also known as the Green Arboreal Alligator Lizard.
This lizard is restricted to the humid forests of the Mexican highlands. It is listed as Endangered by the IUCN.
This is mainly due to habitat loss from fires and reforestation but illegal removal of the species for the pet trade is also having a negative effect on their population.

They are an arboreal species that live high up in the canopy above the forest floor. They are typically found at elevations of between 1350m and 2750m.
Their preferred habitat consists of humid temperate forests such as cloud forests, montane forests and pine-oak hardwood forests.
They often live in tropical epiphytes such as bromeliads, which grow on the side of trees. These epiphytes offer the lizards security, shelter and moisture.
