I looked back through all the references I could find and agree now that it is a spiny. It has been changed. Thanks for the help with ID!

Kyle- One possible reason why you may not have been able to see the spines is the fact that it is a small individual.

The photos don't accurately show the nostrils, but I am positive there were no spines. It's something I look for when I find these turtles, and I'm sure of that at least.

After looking into this further though, I am also thinking this is a spiny. I'm not sure of why the nostrils would look different from what I've seen before, since I've come across some that have definite ridges and this one didn't.

It is hard to see inside the nostrils with the photos provided but in the second photo it does look like there are "spines" on the septum. Also, note the "spines" on the anterior end of the carapace. It is definitely a spiny. If you would like another opinion post a few photos on the main forum.

I don't believe so, and here's my reasoning...A spiny has the tubercles inside the nostrils, correct? This one has just plain open nostrils, with no fleshy extentions. Also, the yellow line running down the neck from the eye has always cued "smooth" to me.

Please correct me if I am still wrong, but I do believe this is a smooth softshell. It would be a new county record for Dunn Co, WI I believe, but they have been found slightly farther south in the Chippewa River from where this one was caught.

It is a spiny softshell, Apalone spinifera, not a smooth.
