Boa (BCC — Boa constrictor)

Quick sourced reference values. LOCUS Scales' full breeding/genetics toolset is built specifically for ball pythons — this page is a courtesy reference for other species.

Scientific name
Boa constrictor constrictor
Native range
Northern South America (Brazil, Guyana, Suriname, Peru)
Lifespan
20-30 years
Lifestyle
🌍🌳 Semi-arboreal (mostly terrestrial, climbs occasionally)

Diet: Carnivore — appropriately sized rats, frozen-thawed. Large adults can take guinea-pig-sized prey.

Feeding frequency: Baby: every 5-7 days. Juvenile: every 7-10 days. Adult: every 14-21 days.

Substrate: A naturalistic, humidity-retentive substrate (coconut fiber, soil mix) — matters more here than for BCI given the higher humidity needs. Never pine or cedar.

UVB: Not strictly documented as essential, but low-to-moderate UVB is increasingly recommended by recent sources.

Incubation: Ovoviviparous species (live birth, no egg-laying) — gestation ~100-120 days. Litters vary, average ~15-25 newborns, stillbirths/"slugs" common.

Clutches per mating: Generally 1 birth per successful mating.
Average egg count: 10-50 newborns (average ~15-25).

BCC = the "true" red-tailed boa — bigger and generally more colorful than the BCI, with stricter humidity needs. Notably less common as a pet and more expensive (sometimes thousands of dollars for a pure line), not recommended as a first boa given pickier care and babies that can be harder to start feeding.

🏠 Enclosure size — Baby/juvenile: 36×18×18in · Sub-adult: 60×24×24in · Adult: 84×36×36in minimum

Common questions

Why is the BCC not recommended as a first boa?
Stricter humidity needs than the BCI, a more imposing adult size, and babies have a reputation for being harder to start feeding, with a higher regurgitation risk. Nothing impossible for a motivated beginner, but the margin for error is thinner.
How do I make sure I have a real BCC and not a mislabeled BCI?
Ask the seller for the precise locality (Suriname, Guyana, Peru = BCC; Colombia, Central America = BCI) and be wary of any seller who just says "red-tailed boa" without specifying the species — that's often (not always) a sign of a BCI sold under that name at a markup.
Can I keep it with another snake?
No — a solitary species.
How long before handling a newborn?
Let it settle for at least a week and confirm at least one successful meal before any handling — BCC babies are more easily stressed than BCI at this stage.
