I don't know if my dad noticed this, but when we were fishing last weekend, I noticed a blue claw on a rock, it was the size of toy car. I know there are crawdads in the Smokyes, but a blue crab looking claw?? Anyone know what it could have been............I could be a giant crawdad that was mutated and turned blue.....but thats impossible. I know it's not a crab, I don't think. It made me wonder.
