I think he was asking if there were gators in saltwater and the short answer is yes it happens, usually in more brackish than salt. In '08 when Galveston bay was flooded by the tidal surge from Ike there were dead gators all over the bay, which shows they cannot live in a pure saltwater environment for long, but they do show up. I've even seen one off the beach in Galveston before, small 4 ft. male looking for territory or lost I assumed, but he was in really bad shape and probably didn't live.
There have been unconfirmed reports of American crocs as nearby as Sabine Pass and they are expanding their territory. It would not surprise me if they started to show up more often.
