When gigantism shapes the diet of a superpredator: The Japanese giant salamander's spectacular transition

A study conducted by researchers at the University of Liège on a large population of Japanese giant salamanders—one of the largest amphibians in the world—reveals that above a certain size, a spectacular transition occurs in the diet of this species, propelling it to the top of the river food chain. The Japanese giant salamander (Andrias japonicus)—an endemic and emblematic species of the country—fascinates scientists with its exceptional size, reaching up to 1.5 meters in length.
