Plateau tiger salamander

The plateau tiger salamander or Mexican tiger salamander (Ambystoma velasci) is a species of mole salamander in the Ambystomatidae family. It is endemic to Mexico,[2] although its range might extend to the United States.[1] Its natural habitats are grasslands, including sparse forests and semi-arid grasslands. Breeding takes place in a range of aquatic habitats: deep volcanic lakes, shallow vernal pools, artificial cattle ponds, and intermittent, fish-free stream pools. It exhibits facultative paedomorphosis.[1]

Ambystoma velasci is locally threatened by habitat loss due to urbanization, forest clearance, and water extraction, and also by pollution and the introduction of fish and frogs (Lithobates catesbeianus).[1]
