Habitats:  The Northern Snakehead enjoys spending time living in ponds, lakes, streams, rivers and other freshwater areas. it likes to spend its  vacation time out of the water .  This normally last up to four days if It is kept hydrated/moist. It is  able to get away with being out of water because It can breathe air from the atmosphere using an air bladder that is similar to a pair of lungs. This poses a problem because these fish can move to other bodies of water and competing with native species.
