Turtle encounter

So, I had a bunch of pork fat scraps that I had cut off the stuff I boiled for twice-cooked pork and took it out to the pond. There were several largish slices, one of which got grabbed and dragged to the bottom right away. Then it was likely too big to consume at once, so part floated back to the surface. After a while, the turtle grabbed and chomped on a smallish piece and then it just surfaced near the edge and observed. I stood quite still until, after several minutes, the turtle decided to go after the remaining pieces of fat. He’s got a rather wide mouth that is white on the inside. I am not sure that is the snapper. It’s head looked awfully big, as big as my fist.
