Many years ago...about 1992, we collected two very huge common snapping turtles (Chelydra serpentina serpentina) The carapace length was around 19 inches, we took many measurements. These turtles must've been very old, and ruled the river where they were located. Being kids at the time, we hauled these turtles up into the neighborhood to scare the younger kids. By the time we were done, it was dark, and we decided to keep the turtles in my basement until the next day, and then release them.
I put them in a back storage room and closed the doors. A few hours later, I went down to check on them and one of the giants was gone! We looked all over but no luck. As I sat down on my couch, I looked out the window and there was the turtle in the middle of the street! This turtle pushed the door open, climbed the steps, and pushed open the metal basement doors by itself! I'll never forget it. The next day we released the turtles, and over the years we encountered them many times. In 1995, one of these giants was found dead on a sand bar in the river it called home for many years. It apparantly died of old age. The other giant was never seen again.
Unfortunately, we never photographed the turtles, and I always think about it. But, there are giants out there, because i've seen them.
