Common Garter Snake

Thamnophis sirtalis

The common garter snake (Thamnophis sirtalis) is a widespread and adaptable serpent species found throughout North America, ranging from Canada to Mexico. Recognizable for its vibrant, longitudinal stripes, which can vary in color from yellow and green to blue and red, the common garter snake typically measures between 18 and 54 inches in length. Its slender, supple body is ideal for navigating a variety of habitats, including forests, grasslands, wetlands, and even suburban areas.

These non-venomous snakes are diurnal, often seen basking in the sun or slithering near water sources in search of prey. Their diet is diverse, consisting mainly of amphibians, fish, worms, and small rodents. Garter snakes are known for their unique reproductive strategy, being ovoviviparous, which means they give birth to live young, with litters ranging from 10 to 40 offspring.

Garter snakes play a significant ecological role, helping control pest populations and serving as prey for larger predators. Despite their timid nature, when threatened, they may release a mild musk as a defense mechanism. The common garter snake's adaptability and resilience make it a fascinating and vital component of its ecosystem.
