Description
Boa Constrictor Imperator (BCI)
Boa constrictor imperator
Morph: Hypo Het Albino
Species Overview
-
Size: BCI typically reach 6–8 feet (1.8–2.4 m) in length, with females often larger than males. Adults usually weigh between 15–30 pounds, depending on genetics and husbandry.
-
Appearance: This boa expresses the Hypomelanistic (Hypo) trait, a co-dominant mutation that reduces black pigmentation, resulting in brighter colours, cleaner saddles, and a lighter overall appearance. It is also Het Albino, meaning it carries but does not visually display the recessive Albino gene.
-
Distribution: The natural Boa constrictor imperator is native to Central and South America, ranging from Mexico through Colombia.
-
Habitat: Wild BCIs inhabit tropical forests, scrublands, savannahs, and river edges.
-
Behaviour: Primarily nocturnal ambush predators, boas feed on small mammals, birds, and reptiles. They are strong swimmers and climbers, though adults are largely terrestrial.
Captive Care
-
Enclosure: A naturalistic enclosure is recommended. Adults should be housed in at least a 6′ × 2′ × 2′ enclosure with sturdy climbing branches, cork bark, hides, and plant cover. Bioactive setups with soil-based substrate, live plants, and leaf litter are excellent for enrichment and humidity control.
-
Temperature & Humidity: Maintain a gradient of 80–85°F (27–29°C), with a basking area of 88–92°F (31–33°C). Nighttime drops to 75–78°F (24–26°C) are acceptable. Humidity should remain 55–70%, with a water dish large enough for soaking.
-
Diet: Juveniles feed every 7–10 days on small rodents; adults every 14–21 days.
-
Behaviour in Captivity: Hypo boas are hardy and generally settle well with consistent care. They may display strong feeding responses but usually tolerate handling once acclimated.
- Special Considerations: While selective breeding has produced a wide variety of morphs, their core care requirements remain identical to standard Boa constrictor imperator.
Genetics Note
The Hypo Het Albino involves:
-
Hypomelanistic (co-dominant): Reduces black pigment, producing brighter colours and sharper contrast.
-
Het Albino (recessive carrier): Carries but does not visually display the Albino trait.
