American Crocodiles (C. acutus) is not limited to being a brackish water dweller. They live and thrive in saltwater. What most people refer to as a Saltwater Crocodile (C. porosus) is a larger (although not that much larger when you compare average adults, just when you compare the extremes) into-pacific croc that is no more likely to be found in saltwater than an american croc.
