Texas Garter Snake

 This is a Texas Garter Snake (Thamnophis sirtalis annectans) which is a subspecies of one of the most common snakes in the United States which is the Common Garter Snake.
While non-poisonous, this snake will readily strike at you, and it can bite with teeth like pins. While it is not poisonous, it can cause an infection if the bite of the teeth is not promptly treated with anti-biotic. This snake can move with lighting speed and usually just wants to zip away from you as fast as possible.
