Conservation
Listed as Least Concern by the IUCN Red List, though localized populations face threats from habitat fragmentation, deforestation, and the pet trade.
Physical Description
Head is distinct from the neck with large specialized scales. Eyes feature vertical pupils adapted for nocturnal vision. The specimen in the image displays brownish-grey coloration with lighter blotches, though adults famously possess bright emerald green bodies with white zigzag markings. Scales are small and smooth to keeled.
Size & Dimensions
Average adults reach lengths of 1.5 to 1.8 meters (5 to 6 feet), with maximum lengths occasionally exceeding 2 meters (6.5 feet).
Habitat
Inhabits primary and secondary tropical rainforests, lowland forests, and gallery forests. Typically arboreal, spending the majority of its life high in the forest canopy and sub-canopy near water sources.
Diet & Feeding
Predominantly carnivorous, feeding on birds, small mammals, and bats. Employs an ambush hunting strategy, hanging from branches and seizing prey with elongated front teeth before constriction.
Reproduction
Viviparous (giving birth to live young rather than laying eggs). Females typically produce litters ranging from 5 to 20 young after a gestation period of approximately 6 to 7 months.
Look-alikes
Frequently confused with the Amazon Tree Boa (Corallus hortulana) due to overlapping range and similar arboreal habits. Distinguished by scale structure around the eyes and distinct labial pits.
Conservation Status
Listed as Least Concern by the IUCN Red List, though localized populations face threats from habitat fragmentation, deforestation, and the pet trade.
Cultural Significance
Plays a vital role in tropical ecosystem regulation by controlling populations of small mammals and avian species. Appreciated in herpetoculture for its striking appearance.
Notable Features
Possesses prominent heat-sensing pits along the upper and lower labial scales to detect warm-blooded prey in total darkness, and exceptionally long anterior teeth specialized for gripping prey through dense plumage or fur.
