Common Boa Constrictor

Meet Kaa, our common boa constrictor.

Boa constrictors are pinkish or tan in color, with dark crossbands. Typically, they range in lengths from 20 inches as neonates to 13 feet as adults. Larger members of the Boidae family have heat-sensitive pits on its head, but this snake has more simple heat-sensitive scales. These snakes are solitary and nocturnal.

Boa constrictors are found from northern Mexico to Argentina. They thrive in the most varied habitats. It shows, however, the least inclination toward water. It lives in deserts, wet tropical forests, open savanna, and cultivated fields, and from sea level to moderate elevation. Boa constrictors are both terrestrial and arboreal.
