Here is a picture of the type turtle we have that keeps showing up. reading the description of the eastern Mud turtle and seeing it almost describes the guy we have to a T but if you look at the facial markings there is some differences. The turtle we have that keeps showing up does have the yellow stripes on it's face. I've never compared the two like HARO posted so not real sure what I would be looking at. I always thought they were one and the same but I'm open to learn that they aren't. I still don't think they are a great threat to the pind but at the same time, I also think ANY aquatic turtle can cause some damage to weak, or slow moving fish, Turtles are turtles and they will eat what they can find and catch. Musk turtles, and by the desciption posted Mud turtles as well aren't great swimmers, so they will wait for food to come to them. a slow moving or ill fish could become dinner. That's just part of nature.
