Somehow this old female mud turtle had survived this, now healed, terrible injury

The big female mud turtle, a common mud, Kinosternon s. subrubrum, was walking along in the shallows at riveredge. Carl was scooting along in the canoe, and I, as usual, was a few yards upstream firmly caught in a riveredge snag that had reached out and grabbed me while I tried to take photos.

Carl, who has an intense interest in all things kinosternid had been lured to the shore by a small mud turtle basking on a barely emergent limb. It was the 3rd example we had seen on this morning. This one had dropped from its sunny perch as Carl had neared and the turtle had inexplicably disappeared in the clear shallow water. It was as he was about to accept defeat that Carl noticed the big female in the shallows.

He reached over and as he lifted her from the water he exclaimed “this turtle has had a hard life!” When I glanced over it wasn’t difficult to see what had prompted Carl’s comment. Much of the turtle’s posterior carapace was missing and scarred and a closer look disclosed that part of her lower mandible had been over broken and had healed and although almost imperceptibly healed, most flesh from one temporal area had been scraped clean leaving a noticeable difference in bilateral facial configuration. What, we wondered, could have caused this? Outboard prop? A marauding alligator snapper? The jury is hung on the causative agent but is unanimous on the fact that this old girl has had a hard – a very hard – life.
