The northern snakehead is an introduced species to the Potomac River that is native to parts of Asia. It has been introduced into parts of Florida also. Urban myths say that this fish can walk on land and survive three days out of water. The northern snakehead can survive out of water longer than other fish because of its ability to breathe air, but it does not have the ability to walk on land. This species has spread rapidly because it can spawn up to five times a year and the parents guard the young.
More information on recommended management of this invasive species is available from the Virginia Department of Game and Inland Fisheries.
