Southern Rubber Boa

Charina bottae umbratica

Venom Status:

Non Venomous

 

Characteristics:

Genetic studies and small size (maximum about 22”) have disclosed that the rubber boas in San Jacinto, San Bernardino, Breckenridge, and Tehachapi Mtns,, well south of the range of the northern rubber boa, are a full species rather than a subspecies. Back and sides may vary from black to a light olive-brown. Belly is pinkish or yellowish. Neonates are salmon dorsally and yellowish on the belly. Elliptical pupils. This is a burrowing taxon that also takes advantage of surface rocks and debris for seclusion. When frightened this snake will coil, elevate and its tail above the coils, ostensibly to draw attention away from more vulnerable areas of its body. Ovoviviparous.

 

Unique Features:

Small size, broad but blunt nose, heavy body, elliptical pupils, blunt tail and range are the defining qualities.

 

Habitat and Diet:

Rocky wooded hillsides and other cool woodland situations where these snakes often hide beneath rocks and other surface debris.Preferred prey items are small rodents.
