Worm snakes are slender, small serpents that burrow into soil and can be found throughout North America. They are often mistaken for earthworms due to their similar appearance, and thus earn their name in part. However, there are several other terms that can be used interchangeably with worm snake. For example, they are sometimes called thread snakes, as their slim body resembles a string. Some refer to them as brown snakes due to their natural earthy coloration, while others call them ground snakes or sand snakes based on their preferred habitats. Regardless of the name, these beautiful snakes are fascinating creatures to observe in the wild.
