The northern snakehead (Channa argus) is a fish native to China, Russia, and Korea. In the United States, the fish is considered to be a highly invasive species. It adapts because it is resiliant, and can actually "walk" some distance. Tolerant of heat and cold,wet and almost dry, it is a survivor.
