Lichanura

Lichanura is a genus of non-venomous snakes in the family Charinidae. These snakes are commonly known as rosy boas. They are found primarily in the southwestern United States and northwestern Mexico.

Rosy boas are relatively small snakes, typically reaching lengths of 1 to 4 feet (30 to 120 cm). They are known for their docile nature and attractive color patterns, which often include various shades of pink, orange, brown, and gray. The color variations are highly variable and are often geographically specific, leading to the recognition of several different subspecies or locales.

Lichanura are crepuscular and nocturnal, meaning they are most active during dawn and dusk or at night. They are primarily terrestrial, spending much of their time burrowing in loose soil or seeking shelter under rocks and debris. In the wild, they feed primarily on small mammals, birds, and lizards.

Rosy boas are popular pets due to their calm temperament, manageable size, and relative ease of care. They are constrictors, meaning they subdue their prey by squeezing it until it suffocates.

The current taxonomic classification of rosy boas has seen some debate, with some authorities previously placing them in the family Boidae. The Charinidae family is now generally accepted.
