B.C.I (Type 2 Anery 66% Het Burk's T+ Albino Nicaraguan)

B.C.I (Type 2 Anery 66% Het Burk's T+ Albino Nicaraguan)

Scientific Name: Boa constrictor imperator
Common Name: B.C.I, Type 2 Anery Nicaraguan

Species Overview

Size: Adults typically reach 4–6 feet (1.2–1.8 m) in length, with females generally larger and more robust than males. Adult weight commonly ranges from 10–20 pounds, depending on sex, genetics, and husbandry.

Appearance: This Boa constrictor imperator displays the clean, reduced patterning characteristic of the Type 2 Anery trait, producing subtle contrast and muted tones along the body. Nicaraguan lineage contributes a compact, muscular build, while Burk's T+ Albino influence lightens overall pigmentation, creating soft yellows and creams. The combination produces a refined, visually appealing pattern.

Distribution: Native to Nicaragua, with selective breeding contributing to distinctive patterning and coloration.

Habitat: Inhabits tropical dry forests, forest edges, scrublands, and areas near water sources. Nicaraguan populations often occupy slightly more open and arid habitats.

Behaviour: Primarily nocturnal ambush predators relying on camouflage and stillness. Juveniles may climb low vegetation, while adults are mostly terrestrial.

Captive Care

Enclosure: A naturalistic enclosure is recommended. Adults are well suited to enclosures measuring 4′ × 2′ × 2′ (122 × 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: Despite their smaller Nicaraguan size, these boas are muscular and strong. Planning for long-term housing and assisted handling for adults 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

Type 2 Anerythristic (Recessive): The Type 2 Anery gene removes red pigmentation and darkens the body when expressed in two copies. Single-copy carriers are visually normal but can pass the gene to offspring.

Het Burk’s T+ Albino (Recessive Carrier, 66%): This snake carries a 66% chance of having one copy of the T+ Albino gene. T+ Albino removes most black pigmentation while retaining partial melanin, producing cream, caramel, honey, or light brown tones when expressed in two copies. Single-copy carriers are visually normal but can pass the gene to offspring.

Nicaraguan (Locality): Nicaraguan B.C.I represents a geographically distinct population. It can influence size, pattern, and temperament but does not affect the expression of other genes directly.
