Hello, Frank Indiviglio here. The Rosy Boa (Lichanura trivirgata) and several of the Sand Boas (Eryx spp.) are among the most unique of the 53 species in the family Boidae. They are excellent choices for both beginning and advanced keepers, especially those with limited space. Stoutly-built but averaging only 24-30 inches in length, these “big snakes in a small package” are hardy, relatively easy to handle and breed, and adapt well to small enclosures.
Rosy and Sand Boas have made similar adaptations to their environments, but live on opposite sides of the globe – a phenomenon known as convergent evolution. Both are highly-specialized burrowers, spending most of their time below-ground in warm, dry habitats. Along with the equally-unusual Rubber Boa (Charina bottae) and African Burrowing “Python” (Calabaria reinhardtii), they are classified in the subfamily Erycinae. Read More »
