Granite outcroppings are the most common geologic association inhabited by the rosy boa. Only in rare places does the rosy boa inhabit rockless environments. Coloration of the rosy boa is highly variable, and usually locale-specific. The rosy boa is extremely docile when encountered by humans. In areas with few rocks, the rosy boa uses rodent burrows for concealment. The rosy boa is one of the slowest-moving species of snakes in the world.
