Specific reasons for the decline may include climate change, chytridiomycosis, or volcanic activity, but the main threat is habitat destruction as logging, agricultural activities, and human settlement reduce their often tiny, fragmented ranges. Survey work is being undertaken to assess the status of these salamanders, and to better understand ...
However, the speed of recent climate change is very fast. Due to this rapid change, for example cold-blooded animals (a category which includes amphibians, reptiles and all invertebrates) may struggle to find a suitable habitat within 50 km of their current location at the end of this century (for a mid-range scenario of future global warming).

Japanese giant salamanders in Tottori Prefecture, Japan, showing notable color variation among individuals within the same population. Andrias japonicus skull. The Japanese giant salamander (Andrias japonicus) is a species of fully aquatic giant salamander endemic to Japan, occurring across the western portion of the main island of Honshu, with smaller populations present on Shikoku and in ...
The Chinese giant salamander (Andrias davidianus) is one of the largest salamanders and one of the largest amphibians in the world. [4] It is fully aquatic, and is endemic to rocky mountain streams and lakes in the Yangtze river basin of central China. It has also been introduced to Kyoto Prefecture in Japan, and possibly to Taiwan.
Although the immediate cause of the die offs was the chytrid, climate change played a pivotal role in the extinctions. Researchers included this subtle connection in their inclusive climate-linked epidemic hypothesis, which acknowledged climatic change as a key factor in amphibian extinctions both in Costa Rica and elsewhere.

The largest South China giant salamander, which researchers said is likely the largest amphibian ever recorded, lived during the first half of the 20th century and was housed at the London Zoo for ...
Like most woodland salamanders, the Shenandoah salamander eats mites, flies, small beetles, springtails, and other soil invertebrates. [9] No direct observation of predation of the Shenandoah salamander has ever been reported, but potential predators residing within the habitat of the Shenandoah salamander include ring-necked snakes, short-tailed shrews, brown thrashers, and towhees.

The hindfoot of a wandering salamander is seen just before it takes a step forward. Scientists say its blood-powered toes help this salamander moves hundreds of feet in the air (Photo by William P ...
