Unless they are tagged or have some unique scars, American Alligators are quite hard to tell apart. I’m sure there are subtle differences in size and features that could be identified if one spent some time comparing photographs. But for the most part, I can only suspect some of the alligators I’ve encountered multiple Okefenokee trips are the same as on prior adventures. But when one is recognized, it feels like meeting an old friend!
On our 2020 Okefenokee trip, we came across one of those old friends that I know we have seen before. As soon as I saw it, I immediately remembered the amputated foot and missing lip. Upon returning home I found the blog called Gator Battles about this uniquely scarred gator we spotted in March 2019. In fact, looking at the one-year-old photo, I think it may even be perched on the same log!
