I was going to say crawfish ...
But the turtle has me a bit stumped. The only softshelled turtles I've ever had my hands on are the Florida, Apalon ferox and the gulf coast spiny, Apalone spinifera aspera, which that turtle clearly isn't.
Your assessment of it being one of the smooth shoftshell turtles, Apalone mutica is likely correct but don't take my word for it.
Pretty animal regardless!
I'm agreeing with Markw84. I used to see those when I lived up north.Sure looks like A. mutica A little hard to tell from the picture. A. spinifera would have rough tubercles on the carapace margin behind the neck and more of a sandpaper feel to the carapace. A. spinitera also has a septal ridge in the nose, as most softshells do, while A. mutica does not.
