The Salado Springs salamander (Eurycea chisholmensis) is a species of salamander in the family Plethodontidae. It is endemic to the vicinity of Salado, Texas. [1] [2] Its natural habitat is freshwater springs. It has been found only from a few springs that feed Salado Creek in Bell County, Texas.
Salado culture, or Salado Horizon, [1] was a human culture in the upper Salt River (río Salado) [2] of the Tonto Basin in southeastern Arizona from approximately 1150 CE through the 15th century. Distinguishing characteristics of the Salado include distinctive Salado Polychrome pottery, communities within walled adobe compounds, and burial of ...
Plethodon is part of the family Plethodontidae (lungless salamanders) and the subfamily Plethodontinae.The genus Plethodon can be divided into two subgenera: the nominal subgenus Plethodon, which includes up to 49 eastern species (the bulk of diversity in the genus), and the subgenus Hightonia, [5] which includes 9 species native to the western part of North America.
The salamander tissues contain cells that differentiates slowly, weakly, or not at all, due to intron delay, which gives them regenerative properties, which includes regenerating parts of the face and eye, lungs, liver, heart, and even the spinal cord and brain, and they have been described as "walking bags of stem cells".
When a female salamander arrives at a vernal pool she participates in a congress with other salamanders of her species. Eggs are then fertilized and left in the pool. [6] The pools dry up in the summer so fish and other predators cannot survive: this makes the pools a good place for salamanders to breed and lay eggs.
The salamander is missing its left front leg, implying possible predation. Its legs did not have any distinct toes, rather, it had complete webbing with small bumps on it. It most likely lived in small trees or in tropical flowers. [1] It is unknown how this salamander's lineage arrived to the area, and how it became extinct.

An estimated 1.88 billion individuals of the southern redback salamander inhabit just one district of Mark Twain National Forest alone, about 1,400 tons of biomass. [7] Due to their modest size and low metabolism, they are able to feed on prey such as springtails , which are usually too small for other terrestrial vertebrates.
