I'm sure this is some sort of Slider (RES/YBS) from my limited research, but I really can't decide which. I'm not really into turtles at all, so my eyes aren't trained for them. I did notice that the turtle I helped has a lot of sharp, spikey things near the rear of the shell. (The best photo is the second one.) The photos I've seen of the RES have a lot fewer of those spikes. So do the YBS photos.

I'm leaning toward YBS because of the striped shell and the striped legs.
