Boa Constrictor Imperator (BCI)

Boa constrictor imperator
Form: Normal (Wild-Type)

Species Overview

• Size: Boa constrictor imperator typically reach 6–8 feet (1.8–2.4 m), though females can grow larger. Adults usually weigh 15–30 pounds depending on husbandry.

• Appearance: The Normal, or wild-type BCI, displays the classic boa look: earthy browns and greys with black saddles, a pale underside, and lighter head markings. Tail saddles often show rich brown or reddish tones. This “default” appearance is the foundation from which morphs and selective lines are bred.

• Distribution: Found across a wide range from Mexico through Central America into Colombia.

• Habitat: In the wild, BCIs inhabit tropical forests, savannahs, scrublands, and riverside zones, adapting well to varied environments.

• Behaviour: Nocturnal ambush predators that feed on small mammals, birds, and reptiles. Juveniles often climb more readily, while adults are primarily terrestrial.

Captive Care

• Enclosure: Adults should be housed in at least a 6′ × 2′ × 2′ enclosure with secure hides, cork bark, climbing branches, and foliage. Bioactive enclosures with soil substrate, live plants, and leaf litter are excellent for humidity and enrichment.

• Temperature & Humidity: Maintain a gradient of 80–85°F (27–29°C), with a basking spot of 88–92°F (31–33°C). Nighttime drops to 75–78°F (24–26°C) are acceptable. Humidity should remain 55–70%, with access to a large water dish for soaking.

• Diet: Juveniles should be fed every 7–10 days on small rodents; adults every 14–21 days.

• Behaviour in Captivity: Normal BCIs are hardy, adaptable snakes. They may display strong feeding responses but generally settle well in captivity and tolerate handling.

• Special Considerations: While selective breeding has produced a wide variety of morphs, their core care requirements remain identical to standard Boa constrictor imperator.
