Northern snakehead
Native to the lower Yellow and Yangtze river systems in eastern China, Amur drainage in southeastern Russia and eastern China, and various rivers of the Korean peninsula, with introduced populations in Japan, the United States, central Asia and parts of eastern Europe.
The latter were originally intended to be used for aquaculture projects but the species is now established in a number of rivers and other bodies of water.
Type locality is ‘Chusan Island, China’, corresponding to what is now more commonly referred to as Zhoushan Island in Zhejiang province, eastern China.
