This species, the inspiration for the B movie of that name, has serious consequences beyond that of gobbling up naive locals. This species is described as a voracious predator on other fishes, but will also eat frogs, crustaceans, and even small reptiles, birds, and mammals. Moreover, its native range (Amur River basin in Russia and China) and temperature tolerance (0-30 degrees C) indicate a species that, if introduced, could establish exotic populations throughout most of the contiguous United States. It was found to be established in Maryland in 2002, perhaps also in Florida, and was the most widely available snakehead sold as a live-food fish in the U.S. Although C. argus is not well adapted to land travel, it can survive out of water up to four days breathing oxygen. The likelihood of its becoming more widely established is real.
