Description
B.C.I (IMG Het Leopard Anery 50% Albino)
Scientific Name: Boa constrictor imperator
Common Name: B.C.I, IMG Het Leopard Anery 50% Albino
Species Overview
Size: Adults typically reach 6–8 feet (1.8–2.4 m) in length, with females generally larger and heavier-bodied than males. Adult weight commonly ranges from 15–30 pounds, depending on sex, genetics, and husbandry.
Appearance: This Boa constrictor imperator displays the progressive darkening associated with the IMG trait, which intensifies contrast as the animal matures. The Leopard influence contributes bold, broken pattern elements and enhanced visual complexity, while the Anery gene is carried without visual expression. This individual also carries a 50% probability of Albino genetics.
Distribution: Native to Central America and northern regions of South America.
Habitat: Occupies tropical forests, forest edges, scrublands, agricultural margins, and areas near rivers or wetlands.
Behaviour: A nocturnal ambush predator that relies on camouflage and patience. Juveniles may show increased use of cover or low climbing opportunities, while adults are primarily terrestrial and spend daylight hours concealed.
Captive Care
Enclosure: A naturalistic enclosure is strongly recommended. Adults should be housed in a minimum enclosure size of 6′ × 2′ × 2′ (183 × 61 × 61 cm). Provide multiple hides, sturdy branches, cork bark, and visual barriers. Soil-based or mulch substrates assist with humidity retention and environmental enrichment.
Temperature and Humidity: Maintain an ambient temperature range 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 be beneficial in planted or bioactive setups.
Diet: Juveniles should be fed appropriately sized rodents every 7–10 days. Adults typically feed every 14–21 days, adjusted based on prey size and body condition.
Behaviour in Captivity: Generally hardy and adaptable. Most individuals acclimate well to captivity and tolerate routine handling, though feeding responses can be strong.
Special Considerations: Due to their 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
IMG (Dominant): The IMG gene modifies pattern, producing irregular, reduced dorsal saddles and lighter background colours. A single copy is enough to produce visible effects, while two copies intensify the pattern reduction.
Het Leopard (Recessive Carrier): This snake carries one copy of the Leopard gene, which produces a unique and variable pattern with spots, dashes, and occasionally red or pink belly tones when expressed in two copies. Single-copy carriers are visually normal but can pass the gene to offspring. Homozygous individuals may experience mild digestion issues.
Het Anerythristic (Recessive Carrier): This snake carries one copy of the Anery gene, which removes red pigmentation and produces greys, blacks, and whites when expressed in two copies. Single-copy carriers are visually normal but can pass the gene to offspring.
50% Het Albino (Recessive Carrier): This snake carries a 50% chance of having one copy of the Albino gene from its parents. Albino removes black pigmentation and produces red, orange, and yellow tones when expressed in two copies. Single-copy carriers are visually normal but can pass the gene to offspring.
