 because it's slender, it's tied off with a prehensile tail, it's got scales that enable to support its body in horizontal permission, and it's trying to get its chin over the next branch. And when it does that, it will pull itself over and release the prehensile tail and continue on its way. Okay, so sort of like if I was doing monkey bars, hold on to one, reach and grab with the next, once I've got that, reach and grab with the next. Precisely, but they're better at it because of the way the scales are arranged.
