I’ve had to wrangle snapping turtles a number of times for various reasons. One female was laying in the middle of the bike path during an bicycle event that I was mashaling. I had to pick her up and move her so that no one ran over her. You can’t just pick up a snapper and carry it since they have a tendency to pee in prodigious amounts. Holding 40 lbs of mad turtle at arms length is bad enough but they have very long necks that the trash about and try to bite you while you are holding them at arms length. And they smell really bad.
I also wrangled newly hatched snapping turtles in Kansas that were crossing a road. Mama laid them in a irrigation ditch on the other side of the road from the Missouri River. They are easier to carry then the adults but they smell just as bad.
