Main predators are felids, crocodilians, boa constrictors, & raptors.
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.

No 2 individuals have exact same pattern.
Often eat meals by hanging from high branches by prehensile tails to eat meals.
