Scientific Name:

Charina bottae




Rubber boas can be found in grassland, woodland, and forest habitats


Northern rubber boas inhabit much of the Western United States and range into southern British Columbia


Least Concern (IUCN Red List)

This species is


to the Truckee Meadows.


Northern rubber boas are comparatively small snakes, averaging only 21 to 26 inches in length. They are two-toned with a uniform tan or olive-brown on their upper side (dorsal side) and a yellow or cream underside (lateral side). These boas are smooth and shiny, with very small eyes and a blunt tail.

Fast Facts:

  • These snakes are nocturnal and prefer colder temperatures than most snakes.

  • They are the smallest members of the boa family (Boidae).

  • Rubber boas form a defensive ball if threatened, pulling covering their head and exposing their tail as a decoy. The tip of their tails are stubby and easily confused for a head.

  • They generally live up to 40 or 50 years in the wild.

  • The genus name Charina means graceful in ancient Greek.

  • The largest threat to Northern rubber boas is over-collection for the pet trade, despite that it is illegal to sell wild-caught boas.
