Critically endangered (CR) species face an extremely high risk of extinction in the wild. As of December 2021, the International Union for Conservation of Nature (IUCN) lists 673 critically endangered amphibian species, including 146 which are tagged as possibly extinct.
Molecular studies of extant amphibians based on multiple-locus data favor one or the other of the monophyletic alternatives and indicate a Late Carboniferous date for the divergence of the lineage leading to caecilians from the one leading to frogs and salamanders, and an early Permian date for the separation of the frog and salamander groups.
Climate change also increases both the frequency and intensity of extreme weather events, [7] which can directly wipe out regional populations of species. [8] Those species occupying coastal and low-lying island habitats can also become extinct by sea level rise. This has already happened with Bramble Cay melomys in Australia. [9]
Specific reasons for the decline may include climate change, chytridiomycosis, or volcanic activity, but the main threat is habitat destruction as logging, agricultural activities, and human settlement reduce their often tiny, fragmented ranges. Survey work is being undertaken to assess the status of these salamanders, and to better understand ...
Unlike other salamanders, whose larvae are developed in water, the alpine salamander and its subspecies are a fully terrestrial species in life and gestation. [8] They give birth to live young. [9] Alpine salamanders produce toxic compounds from their skin. [8] These compounds may protect them from both predator and microbial threats. [10] [11 ...
Like most woodland salamanders, the Shenandoah salamander eats mites, flies, small beetles, springtails, and other soil invertebrates. [9] No direct observation of predation of the Shenandoah salamander has ever been reported, but potential predators residing within the habitat of the Shenandoah salamander include ring-necked snakes, short-tailed shrews, brown thrashers, and towhees.

Japanese giant salamanders in Tottori Prefecture, Japan, showing notable color variation among individuals within the same population. Andrias japonicus skull. The Japanese giant salamander (Andrias japonicus) is a species of fully aquatic giant salamander endemic to Japan, occurring across the western portion of the main island of Honshu, with smaller populations present on Shikoku and in ...
The reticulated flatwoods salamander (Ambystoma bishopi) is a species of mole salamander, an amphibian in the family Ambystomatidae. [2] The species is native to a small portion of the southeastern coastal plain of the United States in the western panhandle of Florida and extreme southwestern Georgia .
