Def a DT, and needs a good soaking. I have seen discoloration like that before on a DT that was caught in a fast moving grass fire. It just had enough time to singe his shell before it passed by him.Yes, it is. It also looks like he's had a bit of damage to his shell. All of his scutes should be the color of those on the very top. It almost looks like he's been sitting in water for a very long time. Either that or something caustic.
