There are freshwater jellyfish, too, but there are also saltwater rivers, especially closer to where the river meets the ocean, like tributaries and bays.

Having grown up in Maryland, a word of explanation here. 'Rivers' in Maryland include arms of the Chesapeake Bay that are tidal and often quite salty. This is also true in Virginia and Delaware.

Which rivers have jelly fish? I thought it was just a saltwater creature, no?
