biggest cottonmouth I've ever seen....and this is NOT photo shopped nor is it held out extended to the toward the camera to make it look bigger........my neighbor(Jack Thompson) killed this snake on his farm near Shellman (southwest Georgia) several years ago and he showed me the picture while it was still on his camera the afternoon he killed the snake...
he and his wife were driving around a pond on his farm when they saw what Jack thought was a small alligator's tail sticking out of the grass onto the bare dirt on the field road around the pond...Jack said he stopped the truck and reached in the back and picked up a small spade shovel...he parted the grass above what he thought was a small gator and this huge snake coiled up almost in his face...he swung the spade by reflex and fortunately the blade of the shovel almost severed the snakes head(look close at photo and you can see where he hit the snake)...
Jack said he knew it was a big snake and he got his wife to take a couple of pictures of the snake and he pitched the snake into the pond for the turtles to eat...
Jack was sales manager for local John Deere dealership here and after showing the picture to several people the next day all of whom had never seen a cottonmouth this big (Jack is 6ft 3 in tall so you can see how big this snake is)....Jack took the picture to the local DNR fisheries/game management office....they like all of us including Jack wished he had saved the snake and assured him this snake would have been a state record if they could have physically measured it....
Sadly Jack was killed the following year in a bulldozer accident clearing brush on his farm...
