Here's a pic of my new snapper.

I'm kinda worried. I hope you all can help!
I've been interested in getting an aquatic turtle for a while but didn't want a turtle that requires a basking area. So last week while I was at work I jumped on Craigslist and clicked on the "Pets" link. I came across an add that someone posted to sell their snapping turtles. They were priced pretty low, $20 each. I thought to myself, "this is worth checking out!" I began texting the kid who posted the add and a week later (today) we met up so I could take a look at the turtles. Both of these snapping turtles, although one bigger than the other, seemed to be in great condition! I had a 10g tank waiting at home for the new turtle. When I got home and put the turtle in its new tank I noticed it had a bunch of stuff hanging off of it! Like peeling skin. But it's all over! On its shell and on its skin. I called the kid and asked him about this. He claims its normal and happens a couple times a month sometimes.
•IS THIS NORMAL?
•HOW CAN I TREAT THIS PROBLEM?
•IS THE TURTLE WORTH KEEPING?
