Predator fish that walks and breathes is on the loose in Central Park

These creatures, called snakehead fish, can walk up out of the water and right into our nightmares. They have both gills and an organ located in their "gill arches" that permits them to breathe oxygen. They sometimes come up on land in search of food and can flop on their fins for up to a quarter of a mile...which would probably be comical if it didn't make your skin crawl.
