The number of known amphibian species is approximately 8,000, of which nearly 90% are frogs. The smallest amphibian (and vertebrate) in the world is a frog from New Guinea (Paedophryne amauensis) with a length of just 7.7 mm (0.30 in).
Amphibians are in decline worldwide, with 2 out of every 5 species threatened by extinction, according to a paper published Wednesday in the scientific journal Nature.

A list of amphibians organizes the class of amphibian by family and subfamilies and mentions the number of species in each of them. The list below largely follows Darrel Frost 's Amphibian Species of the World ( ASW ), Version 5.5 (31 January 2011).
The world’s frogs, salamanders, newts and other amphibians remain in serious trouble. A new global assessment has found that 41% of amphibian species that scientists have studied are threatened ...
A 2013 study estimated that 670–933 amphibian species (11–15%) are both highly vulnerable to climate change while already being on the IUCN Red List of threatened species. A further 698–1,807 (11–29%) amphibian species are not currently threatened, but could become threatened in the future due to their high vulnerability to climate change.
As of 2018, the Conservation Needs Assessment had been used in nearly 2,700 assessments for more than 2,300 species of amphibians, or about 31% of all known amphibian species. [15] These assessments focused on anurans at almost 2,400 assessments, while newts and salamanders made up nearly 300 of the assessments, and caecilians made up only ...
The chytrid fungus (Batrachochytrium dendrobatidis) is parasitic to amphibians, and has led to homogenization of amphibians in Central America. There has been relatively little research on homogenization in the herpetofauna , [ 1 ] and according to a 2006 study, introduction of nonnative reptiles has not led to homogenization of reptilian ...
