Epicrates maurus

Closed tropical-type terrarium, semi-arboreal: a mix of floor substrate and sturdy branches / raised platforms for climbing. Favour a sealed enclosure that retains humidity well.

Minimum dimensions for an adult: approx. 120 x 60 x 60 cm (L x W x H). Provide at least two hides (warm side and cool side), sturdy horizontal branches and foliage (real or artificial) for security. Good ventilation remains necessary despite the high humidity in order to avoid stagnant air.

High humidity is essential: maintain 70-90%, with peaks during shedding. Regular misting and/or damp substrate; a good humidity level prevents incomplete sheds. However, avoid a waterlogged substrate and stagnant water, which promote scale rot.

Moisture-retaining substrates, in a thick layer allowing burrowing. Avoid dry softwood chips (pine, cedar), which are toxic and drying. Promptly remove droppings and soiled areas to prevent mould and mites.

Not essential, as it is a nocturnal species. Low-level UVB (2-5% index) remains beneficial for well-being and vitamin D3 synthesis; if provided, include a shaded area and hides allowing the snake to escape it. Photoperiod of about 12 h.

A large bowl of clean water available at all times, wide enough to allow the snake to immerse itself fully (aids shedding and hydration). Change the water frequently; disinfect regularly, as boas often defecate in the water.

Central America and northern South America: Panama, Colombia, Venezuela, the Guianas, as well as Trinidad and Tobago and Marajó Island (Brazil). Tropical rainforests, wooded savannahs and low-altitude riparian zones.

Carnivore (nocturnal predator) — Rodents (mice, young rats) of appropriate size; occasionally chicks/birds.

Preferably feed thawed prey of a diameter close to the widest part of the snake. Juveniles: every 5-7 days; adults: every 10-14 days. A species prone to obesity: do not overdo the feeding schedule. Avoid all handling for 24-48 h after a meal to prevent regurgitation.

Gestation of about 5-6 months after a period of seasonal cooling/cycling. Litters of 10 to 25 live newborns (sometimes fewer). Strong ontogenic colour change: the vivid pattern and iridescence of juveniles fade with age.

• Respiratory infections (too-low temperature, poorly set ventilation or humidity)
• Dysecdysis / incomplete shed (insufficient humidity)
• Scale rot and blister disease on waterlogged or soiled substrate
• Regurgitation (prey too large, temperature too low, or handling too soon after the meal)
• Mites (Ophionyssus) and, in boids, the risk of inclusion body disease (IBD)
