The rubber boa (Charina bottae) is a species of snake in the family Boidae and is native to western North America.

Colors are typically tan to dark brown with a lighter ventral surface but sometimes olive-green, yellow, or orange.

Rubber boas have small eyes with vertically elliptical pupils and short blunt heads that are no wider than the body.

One of the most identifiable characteristics of rubber boas is their short blunt tails that closely resemble the shape of their head.

There have also been rare sightings in Colorado and Alberta in addition to the states/provinces that they are known to thrive in: California, Oregon, Washington, Nevada, Utah, Wyoming, Montana, Idaho, and extending to its northernmost range in British Columbia,[7] around Pemberton,[8] Williams Lake,[7] and Radium Hot Springs.

[9] Rubber boas have been known to inhabit a wide variety of habitat types from grassland, meadows and chaparral to deciduous and conifer forests, to high alpine settings.

Rubber boas also spend a large amount of time under shelter (rocks, logs, leaf litter, burrows, etc.)

[10] Rubber boas are known to never strike at or bite a human under any circumstances but will release a potent musk from their vent if they feel threatened.
