Main predators of adults are raptors, felids, boa constrictors, & caimans. Many reptiles, amphibians, birds, & mammals eat young.
Like most boas, they’re ovoviviparous w/ eggs hatching internally, resulting in 5-20 live young.
Active at night (nocturnal).
Like all boas, they kill prey by constricting/swallowing whole.
They’re highly arboreal.
They’re ambush predators.
They’re very shy in the wild.
Males & females often fight by constricting/mounting each other.
Hybridize w/ closely related Common/Northern Emerald Tree Boas where both species occur.
Camouflage comes in handy for catching prey & hiding from predators.
Often seen in curled positions in trees.
Use thermal receptor pits around mouth to detect prey.
Sexually mature at 2-3 years old.
Females breed once a year or once every other year.

Fun Fact(s):
Great example of parallel evolution-these & closely related Emerald Tree Boas look/behave very similar to Green Tree Pythons of New Guinea/NE Australia. Pythons lay eggs while boas give birth to live young.
These snakes quite defensive & often aggressive (though not as aggressive as Northern Emerald Tree Boas), not hesitating to strike/bite. Have extra long sharp teeth (nearly 2 in) for capturing prey. While nonvenomous & not deadly, bites often require hospital visits & have caused permanent nerve damage.
Due to slow metabolism, they can go months w/o eating/pooping.
