There are requiem sharks that inhabit brackish and freshwater rivers. These sharks have, thus far, only been found in rivers in South and Southeast Asia and Australia. The only other shark known to be found in rivers is the Bull Shark which has the ability to inhabit both saltwater and freshwater.
There are some sharks that can live in freshwater environments, but there aren't a lot that can cross over and live in both. The Bull shark is one that has been shown to have the ability to live in both saltwater and freshwater. Interestingly, they have to produce 20 times more urine when living in freshwater.
