The rubber boa, Charina bottae, occurs along the west coast of North America, from southern British Columbia to southern California, and east through parts of Nevada, Idaho, Montana, Wyoming, and Utah. In Utah, the species occurs in the northern portion of the state, primarily in the Wasatch Mountains.

The rubber boa kills its prey by constriction. Common prey items include shrews, mice, amphibians, lizards, snakes, and small birds. The rubber boa gives birth to live young, usually two to eight young snakes per year, which are born in the late summer or early fall. The species is nocturnal and is active from March to November, becoming inactive during the winter. Rubber boas are commonly found in forests, meadows, and along streams.
