A small to medium sized inoffensive snake, the Common Garter Snake is one of the most common species across its geographical range. Often black or dark brown with yellow stripes and belly scales with black lined scales on its jaw line. Large scales on the head relative to its size and uniform, heavily keeled scales on the body. They can be highly variable in color and pattern. This is a nonvenomous species.


A diurnal snake, Common Garter’s can be found out during the day, warming up on forest edges, rocks and logs during the morning and out on the hunt thereafter. Generally docile but will flee if approach and are capable f biting and musking if handled. They give birth to live young in large numbers, sometimes exceeding 30-40 babies. They can handle warm and very cold temperatures relative to other snakes, which is likely a factor as to why they are so successful across North America. They feed on things like worms, frogs, toads and aquatic prey like small fish and tadpoles.


Often found in wooded areas at both low and medium elevation but can also be found in populated areas. Given their varied prey they can be found near water and or dry forest.


NO SNAKE SHOULD EVER BE HANDLED BY ANYONE BUT EXPERTS: Often confused with Ribbon Snakes, but generally mistaken for venomous species. Regardless, it should be noted that small snakes can be particularly dangerous due to difficulty in properly identifying them and difficulty handling them. As such they should never be handled or approached.
