Endangered (EN) species are considered to be facing a very high risk of extinction in the wild.

No subpopulations of amphibians have been evaluated by the ...

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.

This is a checklist of amphibians found in Northern America, based mainly on publications by the Society for the Study of Amphibians and Reptiles. [1] [2] [3] The information about range and status of almost all of these species can be found also for example in the IUCN Red List of Threatened Species site. [4]
The International Union for Conservation of Nature (IUCN) lists 35 extinct species, 146 possibly extinct species, two extinct in the wild species, and one possibly extinct in the wild species of amphibians. [1] [2]
The recent change in its conservation category in IUCN from Vulnerable to Endangered, arose from the Chile's amphibian reevaluation workshop for the Red List (Soto-Azat et al., 2015). The justification for its current category is due to its limited occupation area (estimated at 264 km2), severe fragmentation of its populations and continued ...
Each individual egg has less than one percent chance of survival. [8] The eggs hatch within seven days and tadpoles take between 15 and 100 days to turn into little toads. The toadlets then leave the breeding pond and begin to forage for prey such as ants, beetles and moths. After 1 year, males reach sexual maturity, however it can take 1–2 ...
