Like most boas, they’re ovoviviparous w/ eggs hatching internally, resulting in 5-20 live young. They’re ambush predators but can also be active hunters as well. Like all boas, they kill prey by constricting/swallowing whole. Like all tree boas, they’re highly arboreal. Sexually mature at 3 years old. Most often nocturnal or crepuscular. Larger older females have larger litters. Numerous infrared heat receptors located in scales along lower/upper lips pick up tiny temperature differences between prey & background. Coloration often aids in camouflage-handy for catching prey & avoiding predators. Rather uncommon in captivity. Also called Annulated Boa & Brown Dog-Headed Boa. Fun Fact(s): These snakes are very shy but much more docile than other Corallus species. No 2 individuals have exact same pattern. Often eat meals by hanging from high branches by prehensile tails to eat meals. These boas can change color, especially when they become lighter at night.
