Contia tenuis, commonly known as the sharp-tailed snake, is a small, secretive reptile found in the Pacific Northwest of North America. It features a slender body with a distinctively pointed tail and smooth, iridescent scales. Preferring moist, shaded areas, it primarily feeds on slugs and is rarely seen due to its reclusive nature.

Contia tenuis, commonly known as the Sharp-tailed Snake, is native to the western regions of North America. Its geographical distribution includes parts of the United States, specifically in the states of California, Oregon, and Washington. It is also found in parts of southwestern British Columbia, Canada.

The Sharp-tailed Snake typically inhabits moist forested areas, grasslands, and chaparral environments. It prefers habitats with loose soil that allows for burrowing and is often found under logs, rocks, or leaf litter. The climate in these regions ranges from temperate to Mediterranean, with wet winters and dry summers.

Contia tenuis occupies a niche as a small, secretive terrestrial snake that primarily preys on slugs and small invertebrates. It is adapted to a burrowing lifestyle, with a diet that allows it to thrive in environments where its prey is abundant. The snake's presence is often an indicator of healthy, undisturbed ecosystems with sufficient ground cover and moisture.
