| Red-sided Garter Snake | Thamnophis sirtalis parietalis | Red or orange stripes on a black or dark brown body with dark spots between the stripes |
The eastern garter snake, Thamnophis sirtalis sirtalis, is the most widespread and commonly found garter snake in North America. It can be found from Canada to Florida and is known for its yellow stripes on a dark body with dark spots between the stripes. The western garter snake, Thamnophis sirtalis, is also commonly found and has black or brown stripes on a lighter body with dark spots between the stripes. The red-sided garter snake, Thamnophis sirtalis parietalis, is found mostly in the northern part of the continent and is distinguished by its red or orange stripes on a black or dark brown body with dark spots between the stripes.
Despite their similarity in appearance, these varieties can have distinct characteristics depending on their geographic location and habitat. For example, some common garter snake varieties are known for their tendency to swim, while others are primarily land-based. Additionally, although they are not venomous, some garter snakes are more resistant to toxins than others.
Native Garter Snake Types in North America
Garter snakes are found throughout North America, but some species are more prevalent in certain regions than others. The following are some of the native garter snake types found in the continent:
| Species | Habitat | Distribution |
|---|---|---|
| Eastern garter snake (Thamnophis sirtalis sirtalis) | Woods, meadows, wetlands, gardens | Eastern and central North America |
| Plains garter snake (Thamnophis radix) | Grasslands, prairies, deserts | Midwestern and western North America |
| Northwestern garter snake (Thamnophis ordinoides) | Forests, fields, wetlands | Northwestern North America |
| California red-sided garter snake (Thamnophis sirtalis infernalis) | Woodlands, grasslands, wetlands | California and Oregon |
Each of these garter snake types has unique characteristics and behaviors. For example, the eastern garter snake is known for its adaptability to various habitats, while the plains garter snake has a higher tolerance for dry environments. The northwestern garter snake is a skilled climber, while the California red-sided garter snake is known for its striking coloration.
Threats to Native Garter Snakes
Despite their prevalence in North America, native garter snakes face many threats to their survival. Habitat loss and fragmentation due to human activities such as urbanization, agriculture, and logging are major issues. In addition, pollution, climate change, and introduction of non-native species pose significant threats to garter snake populations.
Conservation efforts are underway to protect these vital members of North America’s ecosystems. Habitat restoration, public education, and captive breeding programs are just a few of the approaches being taken to ensure the survival of these unique reptiles.
Lesser-Known Garter Snake Species
While common garter snakes may be the most recognizable to the average person, there are many lesser-known garter snake species that are just as fascinating. These snakes may not be as widespread or as well-studied as their more famous relatives, but they are still an important part of the garter snake family.
Wandering Garter Snake
The wandering garter snake, also known as the wandering marsh snake, can be found in wetland areas throughout North and Central America. This species is known for its greenish-gray coloration and its tendency to crawl around in wet vegetation.
One interesting fact about the wandering garter snake is that it has a diet that is almost exclusively made up of amphibians. It is often found near ponds and other bodies of water where it can hunt its prey.
Pacific Garter Snake
The Pacific garter snake is found along the Pacific coast of North America, from Alaska down to California. This species is quite variable in appearance, but is generally characterized by its stripes of red, black, and yellow or white.
One unique aspect of the Pacific garter snake is that it is highly resistant to the toxic secretions of the rough-skinned newt, a common prey item. This allows the snake to eat these newts without being harmed.
Narrow-headed Garter Snake
The narrow-headed garter snake, as its name suggests, has a slender head compared to other garter snake species. It can be found in the southwestern United States, particularly in Arizona and New Mexico.
This species is particularly interesting because it has a diet that includes not only the typical garter snake diet of frogs and small fish, but also other snakes. It is known to eat other garter snake species as well as some venomous snake species like the western diamondback rattlesnake.
As you can see, there is much to learn about the diverse world of garter snake species. These lesser-known types are just a few examples of the fascinating creatures that are waiting to be discovered.
Surprising Adaptations of Garter Snakes
Garter snakes may be small, but their adaptations are mighty. These reptiles have developed unique traits to help them survive and thrive in diverse habitats and situations.
Resistance to Toxins
Some garter snake species are known for their resistance to toxins, which allows them to prey upon animals that would be lethal to other predators. For example, the common garter snake (Thamnophis sirtalis) can eat toxic newts without being harmed. The evolutionary adaptation that allows them to do this involves a protein called Na+/K+-ATPase in their cells, which pumps sodium out of the cells in exchange for potassium. This process helps the snakes resist the toxic effects of newt skin secretions.
Swimming Ability
Garter snakes are also adept swimmers, allowing them to hunt in aquatic environments and cross rivers and streams to find new habitats. They use a lateral undulation movement, similar to that of eels, to propel themselves through the water.
Diverse Diet
Garter snakes have a varied diet, feeding on anything from earthworms and slugs to fish and amphibians. Some species have even been known to feed on other snakes. This varied diet allows them to adapt to different environments and sources of food.
Regenerative Abilities
Another interesting adaptation of garter snakes is their ability to regenerate some parts of their body. If a garter snake loses its tail during a predator attack, it can regrow a new one. This process is called autotomy, and it allows the snake to escape from predators while leaving behind a wriggling tail as a distraction.
Garter snakes are remarkable creatures that have evolved an impressive array of adaptations to help them survive in diverse environments. From their resistance to toxins and their swimming abilities to their varied diet and regenerative abilities, these reptiles continue to fascinate and amaze us.
Threats and Conservation Efforts for Garter Snakes
Garter snakes are facing a number of conservation threats due to a range of factors including habitat loss, climate change, invasive species, and direct human impacts.
