Newer phylogenetic research supports the original arrangement, but herpetologists still do not agree on rosy boa taxonomy.
Four subspecies at the most are recognized: Considered a small snake, the desert rosy boa normally attains a total length (including tail) of 43–112 cm (17–44 in).
Almost all specimens of the desert rosy boa have at least some trace of three longitudinal stripes, one down the center of the back, and two on the lower sides.
The desert rosy boa spends most of its life concealed beneath rocks and in crevices to escape the elements and natural predators.
Throughout most of its range, the winter is too cold for these functions and the desert rosy boa goes into a dormant state called brumation.
Most specimens of the desert rosy boa are encountered in spring as they leave the security of their rock piles and crevices to seek mates.
The surface activity of the desert rosy boa can take place during any hour of the day, but during hot weather, it is primarily nocturnal.
Because most populations of the desert rosy boa live in exceedingly dry habitats, activity is often highly moisture-dependent.
Its extreme docility, few needs, and attractive coloration have made the desert rosy boa popular with herpetoculturists.
The desert rosy boa bears live young, about six in a brood, with newborns up to 30 cm (12 in) in length.
[7] Its generally docile temperament and small size make the desert rosy boa an ideal choice for a pet snake.
