1. Garter snakes, garden snakes, ribbon snakes (Thamnophis genus)
There are 30 species and lot of subspecies species of Tamnophis genus of snakes which are widely spread throughout the Northern American continent, and are one of the most common snakes in America. They inhabit various regions from Canada to the south of the US, preferring more humid and water rich areas, so they occur more rarely in arid regions. Their habitats include forests, grasslands, and meadows and tend to be near water areas. Garter snakes are considered to be non-venomous snakes, and often kept as pets, though some researches have shown that they do produce tiny portions of venom, that can stun small animals they prey on. Since there are many species of these snakes, their average body length varies around 50-70 centimeters and rarely goes beyond 1.5 meters. They are usually recognizable by several stripes that longitudinally spread from head to tail, with patches in between. The color of the stripes is usually lighter, yellowish and greenish, and the background color is darker.
