The largest alligators are said to have been from 15 to 19 feet long. I don’t think any of those 19-footers were scientifically verified, but an internet search shows Mandy Stokes’ 15’9” alligator holds the current world record. The largest Georgia alligator was killed in 2019 and measured 14’1”.
I haven’t climbed out of my canoe with a tape measure in the Okefenokee Swamp, but have seen some pretty big ones along the banks of Billy’s Lake and especially up The Sill. It is hard to imagine these gargantuan reptiles can weight up to 1,000 pounds! Once they get up to that size, I don’t think they have any fear of predators… other than during hunting season. But if they remain within the boundaries of the Okefenokee National Wildlife Refuge, they are protected for life to grow big and fat!
