Description
Boa Constrictor Imperator (BCI)
Boa constrictor imperator
Morph: Type 2 Anery
Species Overview
-
Size: Boa constrictor imperator typically grow 6–8 feet (1.8–2.4 m), with females usually larger than males. Adults weigh 15–30 pounds depending on husbandry.
-
Appearance: The Type 2 Anerythristic (Anery) morph eliminates red pigmentation, producing a cooler-toned boa with shades of grey, silver, and black contrasted against a lighter underside. Compared to wild-type BCIs, Type 2 Anery boas have a sharp, high-contrast look and a cooler overall palette.
-
Distribution: The natural Boa constrictor imperator ranges from Mexico through Central America into Colombia.
-
Habitat: Wild BCIs inhabit tropical forests, savannahs, scrublands, and riversides.
-
Behaviour: Nocturnal ambush predators feeding on small mammals, birds, and reptiles. Juveniles may climb frequently, while adults are more terrestrial.
Captive Care
-
Enclosure: A 6′ × 2′ × 2′ enclosure is suitable for adults, with secure hides, climbing branches, cork bark, and foliage. A naturalistic or bioactive setup with soil substrate, leaf litter, and live plants helps maintain humidity and enrichment.
-
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 be kept at 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: These boas are hardy and generally adapt well to captivity. 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 Type 2 Anery involves:
-
Type 2 Anerythristic (recessive, expressed): Removes red pigmentation, producing cooler shades of grey, black, and silver. This distinguishes it from other Anery lines, such as Type 1.
