Amphibian species (IUCN, 2025-2)
  • 8052 extant species have been evaluated
  • 7156 of those are fully assessed[a]
  • 4186 are not threatened at present[b]
  • 2931 to 3827 are threatened[c]
  • 35 to 148 are extinct or extinct in the wild:
    • 37 extinct (EX) species[d]
    • 2 extinct in the wild (EW)

  2. ↑ NT and LC.
  3. ↑ Threatened comprises CR, EN and VU. Upper estimate additionally includes DD.
  4. ↑ Chart omits extinct (EX) species
Vulnerable (VU) species are considered to be facing a high risk of extinction in the wild.

As of December 2025, the International Union for Conservation of Nature (IUCN) listed 814 vulnerable amphibian species.[1] Of all evaluated amphibian species, 10.1% are listed as vulnerable.

For a species to be assessed as vulnerable to extinction the best available evidence must meet quantitative criteria set by the IUCN designed to reflect "a high risk of extinction in the wild". Endangered and critically endangered species also meet the quantitative criteria of vulnerable species, and are listed separately. See: List of endangered amphibians, List of critically endangered amphibians. Vulnerable, endangered and critically endangered species are collectively referred to as threatened species by the IUCN.

Additionally 896 amphibian species (11.1% of those evaluated) are listed as data deficient, meaning there is insufficient information for a full assessment of conservation status. As these species typically have small distributions and/or populations, they are intrinsically likely to be threatened, according to the IUCN.[2] While the category of data deficient indicates that no assessment of extinction risk has been made for the taxa, the IUCN notes that it may be appropriate to give them "the same degree of attention as threatened taxa, at least until their status can be assessed".[3]
