The golden toad of Monteverde, Costa Rica, was among the first casualties of amphibian declines.Formerly abundant, it was last seen in 1989. Since the 1980s, decreases in amphibian populations, including population decline and localized mass extinctions, have been observed in locations all over the world.
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). The largest living amphibian is the 1.8 m (5 ft 11 in) South China giant salamander ( Andrias sligoi ), but this is dwarfed by prehistoric temnospondyls such as Mastodonsaurus which could reach up to 6 m ...
The Amphibian Ark (or AArk) was formed in 2007 by three principle partners: the World Association of Zoos and Aquariums (WAZA), the IUCN/SSC Conservation Planning Specialist Group (CBSG), and the IUCN/SSC Amphibian Specialist Group (ASG) in response to extreme declines in wild amphibian populations.

Traditionally considered a subclass of the class Amphibia, modern classification systems recognize that labyrinthodonts are not a formal natural group exclusive of other tetrapods. Instead, they consistute an evolutionary grade (a paraphyletic group ), ancestral to living tetrapods such as lissamphibians (modern amphibians) and amniotes ...
China is home to 346 species of amphibian. [1] China's amphibian diversity is greater than any other country in the Old World, and it is the 5th in the whole world.China's amphibian fauna includes an important element of widespread, generally non-threatened species though 27.3% of amphibian species are extinct or threatened and because conservation assessments of Chinese amphibians have only ...
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]
