The Rosy Boa is a small constrictor snake living in North America. It is one of only two Boidae species in the United States, the other being the Rubber Boa. It inhabits the southwestern US and northern Mexico
[edit] Description
About four feet long, smooth and shiny. It comes in various colors, and usually has three stripes running the length of the body; two lateral stripes and one dorsal stripe. Rosy boas are one of the smaller members of the boa family. Like many boas and pythons, they are nocturnal (sometimes crepuscular), thus moving around mostly at night or around dawn and dusk. Rosys may live in excess of 15 years. Rosys look much like their cousins, the Rubber boa (Charina bottae). Rosy heads are set off slightly more from their bodies, and the tops of their heads are covered with numerous small scales, rather than the fewer, but much larger, scales of the Rubber boa. Rubber boas have blunt, rounded tails while the Rosy tails are more tapered, ending in a rounded tip.
[edit] Subspecies
There are currently four subspecies of rosy boas; as with the classification of many animals, the taxonomists frequently dispute the species and subspecies designations. As more information is learned about the physiognomy and range of the animals in question, these may change Currently, the subspecies designations for the rosy boas are:
- L. trivirgata Rosy Boa. to 40 in (100 cm). Ranges through southwestern U.S. (southern California, Arizona, and northern Mexico). Ground color slate gray or brown.
- L. t. trivirgata Mexican Rosy Boa. Ground color laced with pale, creamy broad longitudinal stripes.
- L. t. roseofusca Coastal Rosy Boa. Ground color laced with blotchy reddish-brown longitudinal stripes.
- L. t. gracia Desert Rosy Boa. Ground color laced with well-defined pink, orange or tan longitudinal stripes.
