Have you seen a white beautiful snake before? This Leucistic Texas Rat Snake is a lovely lady in white. She gets her coloring and the "leucistic" element of her name from a condition that results in a lack of all pigmentation, rather than just melanin which appears in albinism. This is why her eyes are of normal color. Texas Rat Snakes are (obviously) found in Texas as well as in Arizona and Louisiana. They are non venomous so a bite will give you little more than a sore leg.
