Locality

Sierra Tarahumara lies in the northern state of Chihuahua, Mexico.  This vast area of high peaks, forested plateaus and deeply eroded riparian canyons is sometimes referred to as Mexico’s rugged “Western Mother Mountains”. High above the harsh desert floor at elevations over 4000’ are the Ponderosa pine forests. It is here where these “dwarf” boas (B. constrictor ssp.) originated.

History in culture

A researcher from the University of Arizona (UA) brought back a single pair of these boas in the early to mid 1990’s.  That pair made their way into the private sector where soon after an Arizona collector bred them.  That first breeding resulted in a single live male.  In the 1998/1999 season they bred again, ten babies with a high male ratio were born.  Rio Bravo Reptiles did acquire a male/female pair of these boas in early 2001 from an associate here in Texas. By the winter of ‘02 the 3-1/2 year old boas had grown to 37” in length. This year (2002) both myself and Graham Criglow of Bryan, TX successfully produced healthy litters of Tarahumara dwarf boas. Amazingly, both litters (9&10 respectively), were born the morning of July 3rd. Whether this is simple coincidence or driven by something in their genetic makeup is unknown. Prior to these breedings there existed only the original 13 animals (1.1 WC original pair, 1.0 1st breeding baby and 0.0.10 2nd breeding babies) in our hobby.  The pair maintained here and those held by Mr. Criglow are the only Tarahumara boas known to have been kept together and bred pure for their unique locality.
