Habitat: Wide range of habitats, rainforest clearings, woodlands, grasslands, dry forests, semi-desert
Average Size: 6-12’, females tend to be larger (most are 5-8’)
Average Lifespan: 20-30 years
Captive Care: Large enclosure (suggest 4x2x2 minimum size for adult), undertank heating on one side; substrate: newsprint, dried aspen, Care Fresh; water bowl large enough for soaking (e.g., large litter box), fresh water at all times; shelter, will climb if provided branches and an elevated resting platform. Young require smaller caging. Humidity 60-70% - may have shed issues if not humid enough. If this happens, soaking in tepid water for ~30 minutes will help.
Temperature: Gradient of 75˚F (23.5˚C) to 85˚F (29˚C), with basking spot (undertank heat) 90-95˚F (31-34.5˚C)
Lighting: No special lighting required. Low wattage fluorescent bulb can be used to provide day/night cycle.
Diet: Eats mice, rats, rabbits, and/or chicks. Feed young every 7-10 days adults every 10-14 days. Food as big around as the widest part of the snake’s body. Do not handle snake for a day or two after feeding (larger boas may need 4-5 days to fully digest their meal). Frozen-thawed food preferred.
Breeding: Usually during dry season (April to August), ovoviviparous – gestation 5-8 months, average litter 25.
Temperament: Can be calm, but easily spooked if move too quickly in front of them.
Notes: Heavy bodied, powerful constrictor with large head and large teeth; care must be exercised in handling. Enjoy climbing (semi-arboreal).
