i know that in southern IL there are historic records of alligator snappers which makes them protected and are listed endangered which would make them illegal to own in IL. So i am not sure if they are native to indiana (i don't think so) but you never know with historic records and all. But it could be the 4 inch rule, or it could be state laws focusing on endangered species not just native but national. You should be able to find state and local laws that concern restrictions and all. But they do get BIG!


good luck
