A Slender Glass Lizard.
Often mistaken for a snake, these are actually lizards that have secondarily lost their legs (well, I guess snakes did too).
If you compare the face of this lizard to another lizard versus a snake, the difference is very noticeable.
They get their name "Glass Lizard" because they can, and will, break their tails off at the slightest stress, like they're "made of glass."
