Description
B.C.I (Super Hypo)
Scientific Name: Boa constrictor imperator
Common Name: B.C.I, Super Hypo
Species Overview
Size: Adults typically reach 6–8 feet (1.8–2.4 m) in length, with females generally larger and more robust than males. Adult weight commonly ranges from 15–30 pounds, depending on sex, genetics, and husbandry.
Appearance: This Boa constrictor imperator exhibits the clean, reduced patterning characteristic of the Super Hypo trait, resulting in a lighter overall appearance with muted tones and subtle contrast. Colouration often includes soft browns, tans, and golds, producing a visually appealing and delicate pattern.
Distribution: Native to Central America and northern regions of South America.
Habitat: In the wild, B.C.I inhabit tropical forests, forest edges, scrublands, and areas near water sources.
Behaviour: Primarily nocturnal ambush predators that rely on stillness and camouflage. Juveniles may climb low vegetation, while adults are mostly terrestrial.
Captive Care
Enclosure: A naturalistic enclosure is recommended. Adults should be housed in a minimum size of 6′ × 2′ × 2′ (183 × 61 × 61 cm). Include multiple hides, cork bark, sturdy branches, and visual barriers. Soil-based or mulch substrates support humidity retention and encourage natural behaviours.
Temperature and Humidity: Maintain ambient temperatures of 80–85°F (27–29°C), with a basking area of 88–92°F (31–33°C). Nighttime temperatures may drop to 75–78°F (24–26°C). Humidity should remain between 55–70%, supported by a large water dish and occasional misting.
Lighting: Standard ambient lighting on a consistent day–night cycle is sufficient. Low-output UVB is optional and may benefit planted or bioactive enclosures.
Diet: Juveniles should be fed appropriately sized rodents every 7–10 days. Adults typically feed every 14–21 days, adjusted for body condition.
Behaviour in Captivity: Generally hardy and adaptable. Most individuals acclimate well to captivity and tolerate handling, though feeding responses may be strong.
Special Considerations: Due to potential adult size and strength, long-term housing plans should be considered early. Larger individuals may benefit from assisted handling, and having a second set of hands is recommended for safety and control.
Taxonomy Note
Boa constrictor imperator is a member of the family Boidae, a group of non-venomous constricting snakes native to the Americas. Formerly classified as a subspecies of Boa constrictor, B. imperator is now widely recognised as a distinct species based on genetic, morphological, and geographic evidence, with a natural range spanning much of Central America and extending into parts of northern South America. In captivity, this species is valued for its adaptability, generally steady temperament, and extensive diversity of selectively bred colour and pattern traits, all of which retain consistent core behaviours and care requirements across standard B.C.I forms.
Genetics Note
Super Hypomelanistic (Recessive): The Super Hypo gene reduces black pigmentation more intensely than standard Hypo, producing very clean, light background colours and high contrast. Single-copy carriers are visually normal but can pass the gene to offspring.
