I assume a lot of you have seen Oddball's post about alligator snappers being split up into three separate species (Macrochelys Temminckii, Macrochelys Apalachicola, and Macrochelys Suwanneensis). I was curious if anybody knows how to tell them apart? From what I've read so far, the only way to tell is to find out what waterway they originate from (Mine is captive bred so I'm clueless when it comes to that). There's limited information out there on the web right now so I was wondering if any of you guys know? I bought a little AST a few months ago and I'm curious about what kind he is.
