Endangered (EN) species are considered to be facing a very high risk of extinction in the wild. As of September 2021, the International Union for Conservation of Nature (IUCN) lists 1085 endangered amphibian species. [1] Of all evaluated amphibian species, 14% are listed as endangered. No subpopulations of amphibians have been evaluated by the ...
As of 2010, the IUCN Red List, which incorporates the Global Amphibian Assessment and subsequent updates, lists 650 amphibian species as "Critically Endangered", and 35 as "Extinct". [4] Despite the high risk this group faces, recent evidence suggests the public is growing largely indifferent to this and other environmental problems, posing ...
It can reach up to 50 kg (110 lb) in weight and 1.8 m (5.9 ft) in length, making it the second-largest amphibian species, [4] [8] after the South China giant salamander (Andrias sligoi). [18] The longest recently documented Chinese giant salamander, kept at a farm in Zhangjiajie , was 1.8 m (5.9 ft) in 2007. [ 6 ]
The bleeding toad, fire toad or Indonesian tree toad (Leptophryne cruentata) is a species of true toad in the amphibian family Bufonidae, endemic to Java, Indonesia. [1] [2] L. javanica was, formerly, synonymous with the bleeding toad prior to its description as a distinct species in 2018, [1] although the degree of differentiation between these species is low.

Primary threats to this species include its restricted range, loss of habitat, a low reproductive rate, and a limited capability of dispersal. Of the approximately 63,000 acres (250 km 2 ) of remaining habitat, about 60 percent is currently owned or leased by paper companies which primarily use a clear-cut system of forest management.
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. [1] [2] 9.2% of all evaluated amphibian species are listed as critically ...
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 1567 amphibian species (24% of those evaluated) are listed as data deficient, meaning there is insufficient information for a full
In 2004 a sample of peptides from nine different adult amphibians in Omar Torrijos National Park, Panama were taken to test for susceptibility to chytridiomycosis. Of the 9 species tested the lemur leaf frog ranked third in immunologic resistance with a mean of 15% in inhibition of pathogen growth and peptide renewal.
