Rubber Boa

The Coastal Rubber Boa is a type of boa (snakes belonging to the family Boidae). It is one of the most docile boas alive. Rubber Boas are one of only two boas native to the USA, the other being the Rosy Boa.The Southern Rubber Boa (Charina umbratica) is a closely related species found only in Southern California. Some consider it to be merely a subspecies of Charina bottae.The rubber boa is a primitive snake compared to its much larger relatives native to Latin America, which include the Boa Constrictor, Emerald Tree Boa, and Green Anaconda. The rubber boa has retained the club-like tail of its Erycine ancestors. The blunt tail of the rubber boa is used as a decoy to deter predators from attacking its head.
