Burrowing snakes are a group of snakes adapted to life underground. They have elongated, cylindrical bodies and smooth scales that help them move easily through soil and sand. These snakes typically have small or reduced eyes and may lack external ear openings, which are adaptations for their subterranean lifestyle. Common examples of burrowing snakes include the Eastern Hognose Snake and the Sand Boa. They primarily feed on small mammals, insects, and other invertebrates found in their burrows. Burrowing snakes play an important role in their ecosystems by helping to aerate the soil and control pest populations.
