Description
B.C.I (Chocolate T+ Albino Black Eyed Anery "T+ Snow" Nicaraguan)
Scientific Name: Boa constrictor imperator
Common Name: B.C.I, Chocolate T+ Albino Black Eyed Anery Nicaraguan
Species Overview
Size: Adults typically reach 6–8 feet (1.8–2.4 m) in length, with females generally larger than males. Adult weight ranges from 15–30 pounds, depending on genetics and husbandry.
Appearance: This morph combines Chocolate T+ Albino with Black Eyed Anery traits and Nicaraguan bloodline influence. Chocolate T+ Albino produces warm, high-contrast cream, yellow, and chocolate tones. Black Eyed Anery removes red pigment when expressed, and the Nicaraguan bloodline enhances pattern clarity and contrast. The result is a visually striking boa with clean, well-defined saddles and bold colouration.
Distribution: Native to Central and South America, with Nicaraguan bloodlines contributing to the albino and pattern traits.
Habitat: Occupies tropical lowlands, forest edges, and semi-arid areas. Often found near rivers or lowland scrub forests.
Behaviour: Primarily nocturnal ambush predators, feeding on small mammals, birds, and reptiles. Excellent swimmers and climbers, though adults are mostly terrestrial.
Captive Care
Enclosure: A naturalistic setup is strongly recommended. Adults should have at least a 6′ × 2′ × 2′ (183 × 61 × 61 cm) enclosure with sturdy branches, hides, cork bark, and plant cover. Bioactive environments with soil substrate, leaf litter, and live plants help maintain humidity and provide enrichment.
Temperature and Humidity: Maintain a gradient of 80–85°F (27–29°C), with a basking spot of 88–92°F (31–33°C). Nighttime can drop to 75–78°F (24–26°C). Humidity should remain between 55–70%, with access to a water dish large enough for soaking.
Lighting: Standard ambient lighting is sufficient. Low-level UVB is optional but can benefit live plants in naturalistic setups.
Diet: Juveniles feed every 7–10 days on appropriately sized rodents; adults feed every 14–21 days on larger prey items.
Behaviour in Captivity: Hardy and generally tolerant of handling. With consistent, calm husbandry, most individuals become manageable pets.
Special Considerations: Due to their potential adult size of 6–8 feet (1.8–2.4 m), it is important to plan for future housing. Handling large adults can be challenging; having a second person assist is recommended for safety and stress reduction.
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
T+ Albino (Recessive): T+ Albino is a recessive albino form that removes most black pigmentation but retains 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 genes to offspring.
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.
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.
T+ Snow (Combination Morph, Visual): The T+ Snow morph refers to snakes visually expressing both T+ Albino and Type 2 Anery. This combination produces a light, high-contrast appearance with cream and honey tones, partial melanin retention, and subtle pattern contrast, while retaining the potential to produce T+ Albino or Type 2 Anery offspring when bred.
