The largest living amphibian is the 1.8 m (5 ft 11 in) Chinese giant salamander (Andrias davidianus) [41] but this is a great deal smaller than the largest amphibian that ever existed—the extinct 9 m (30 ft) Prionosuchus, a crocodile-like temnospondyl dating to 270 million years ago from the middle Permian of Brazil.

Many of the causes of amphibian declines are well understood, and appear to affect other groups of organisms as well as amphibians. These causes include habitat modification and fragmentation, introduced predators or competitors, introduced species, pollution, pesticide use, or over-harvesting.
Ichthyophis is a genus of caecilians (limbless amphibians, sometimes called the Asian caecilians) found in Southeast Asia, the southern Philippines, and the western Indo-Australian Archipelago.

Amphibia - The Amphibian Species of the World (AMNH database) together with Frost et al.. Taxonomy in Wikipedia is mostly in sync with the ASW one. List showing discrepancies is available here: Wikipedia talk:WikiProject Amphibians and Reptiles/Amphibian taxonomy (lasted updated 31 March 2014). Reptilia - ITIS, Reptilia (higher level ...
This is because, although its range is probably less than 20,000 square kilometres (7,700 sq mi), it is locally common in the areas in which it lives and does not seem to have any significant threats. It is a very adaptable animal and can cope with changes in its habitat.
It is estimated that at least thirty percent of amphibian species are currently at risk of going extinct, [10] though some estimates put this figure closer to forty percent. [11] The threats to amphibian populations are diverse, but predominantly anthropogenic, including over-exploitation, habitat loss, introduction of invasive species, and ...
Ichthyophis sumatranus, also known as the Sumatra caecilian, is a species of amphibian in the family Ichthyophiidae. It is endemic to Sumatra , Indonesia . [ 1 ] [ 3 ] It is known from western Sumatra, but many records lack precise location data and its exact range is poorly known.
