The Leora's stream salamander or ajolote (Ambystoma leorae) is a rare species of mole salamander in the family Ambystomatidae. It is endemic to a very small area of land in the Iztaccihuatl-Popocatepetl National Park on the border of the State of Mexico with Puebla, with a single known population on Mount Tlaloc. Its very specific requirements as regards water quality militates against its survival in a habitat where water is being extracted, cattle graze and the salamander has traditionally been eaten as food. It has been listed as a threatened species by the Mexican Government and as critically endangered by the International Union for Conservation of Nature.
