Description
Diet
With the Japanese Giant Salamander living its entire life in the water the diet consists of freshwater fish, frogs, and crabs. Due to the slow metabolism of the salamander the species can go without eating for days.[2]
Behavior
Conservation
Due to the species being highly endemic, the biggest threat to the Japanese Giant Salamander is habitat loss. This is due to human activity damming up riverbeds and freshwater sources occupied by the Giant Salamander. Climate change is also a source for concern to the Japanese Giant Salamander due to estimated rainfall increasing leading to the destruction of streambeds.[3] Other sources of threats are pollution and the introduction of invasive species into Japan specifically the Chinese Giant Salamander.[4] This introduction of the Chinese Giant Salamander has lead to hybridization between the two species, posing a big threat to the native species. Studies done from 2011 to 2013 showed that 95% of all Japanese Giant Salamanders captured were hybrids, and were captured in multiple locations.[5]
