Continuing with the eye theme to round out the week, this is a green parrot snake that appears to have lost an eye. All three photos are of the same snake. The top photo shows the snake’s injured right eye — a solid black color. In the second photo you see the right eye, the normal yellow color. The third photo shows both eyes. Messed up eye or not, the green parrot snake is most certainly one of the finest looking serpents around — not to mention harmlessly non-venomous.
