Colombian Red-Tailed Boa Constrictor


Boa constrictors are one of the few species where their scientific name and their common name are the same. Boas are non-venomous snakes. Their jaws are lined with small, recurved (hook-shaped) teeth for gripping and holding onto prey while they wrap their muscular bodies around it, constricting, or squeezing, it. If boa constrictors are presented with dead prey, they still constrict the food item before consuming it - this is an instinctual behavior. They are very capable swimmers, even younger and smaller boas are able to climb trees. Boa constrictors possess pelvic spurs. These are hind leg remnants found of either side of the cloacal opening. They are used by males in courtship and are larger in males than in females.

Our Current Residents

Leroy, Male - Born 2013 (estimate)

Leroy came to ZooMontana in 2018 as a pet surrender. His owner placed a heat source inside his habitat (likely a small aquarium or tub) and put Leroy on top of it, creating significant burns. The burns have since been healed up, and Leroy is now an ambassador within the Education Department.  He is the largest and heaviest snake at the zoo.
