Food
Giant salamanders do not have good eyesight and perceive external information mainly through smell and touch. They can also sense vibrations in the water through the warts on their skin, which in turn catch fish and shrimp as well as insects in the water.
The Chinese giant salamander occupies a position at the top of the food chain in the ecosystem in which it lives, and is an important link in the biological chain. Chinese giant salamanders have slightly different food sources in different waters. They are large eaters, mainly preying on fish, crustaceans, amphibians, and small arthropods in the water, and a small amount of plant matter is also found in their stomachs.
Living in the Yangtze River Basin, the giant salamander's habitat is home to fish such as white snappers, wide-mouthed light-lipped fish, and horse mouthed fish, which provide a wide range of prey for the salamander.
