The Bolivian Short-Tailed Boa, also known as Boa constrictor amarali, is a medium-sized boa species native to Bolivia, southern Brazil, and Paraguay. This subspecies is distinct for its shorter length and stouter build compared to the more commonly seen Boa constrictor imperator. Its calm temperament and manageable size make it a popular choice among boa enthusiasts and intermediate keepers alike.

First described in 1952 by Brazilian herpetologist Afrânio do Amaral, B. c. amarali is sometimes referred to as the Bolivian Amarali Boa. Despite being part of the Boa constrictor complex, it is genetically and behaviourally distinct, with no formally recognized subspecies. It is listed under CITES Appendix II due to habitat loss and overcollection in the wild.

In its natural environment, the Bolivian Short-Tailed Boa inhabits dry tropical forests, scrublands, and semi-arid plains. These boas are nocturnal and primarily terrestrial, often found hiding under debris or within burrows during the day. Adults typically reach lengths of 4 to 6 feet (48–72 in) and exhibit a more muscular, robust body compared to other boas of similar length. Their colours range from earthy tans and browns to soft greys, marked with bold dark saddles and lateral blotching that helps them blend seamlessly into the dry forest floor.

Juveniles may display defensive behaviours such as hissing or mock strikes, but with regular, gentle handling, most individuals settle into calm, inquisitive pets. They are typically long-lived, with a lifespan of 20–30 years in captivity when properly cared for.

These boas are carnivorous constrictors, feeding primarily on small mammals and birds in the wild. In captivity, they readily accept frozen-thawed rodents and adapt well to scheduled feeding routines. Overfeeding should be avoided, as these snakes are prone to obesity when kept in small enclosures or fed too frequently.

In captivity, the Bolivian Short-Tailed Boa requires a secure, well-ventilated enclosure with appropriate heating and humidity levels. A warm side of around 88–92°F (31–33°C) and a cooler end in the low 80s°F (26–28°C) helps them thermoregulate effectively. Humidity should be maintained around 60–70%, with periodic increases during shed cycles. Substrates like cypress mulch or coconut husk help retain moisture while allowing for burrowing behaviour. Hides on both the warm and cool ends of the enclosure are essential for stress reduction. Due to their size and strength, enclosures must be escape-proof and appropriately sized, with a minimum of 4 ft x 2 ft for adults, though larger is always better.

While not as commonly seen as other boa subspecies, B. c. amarali offers a unique combination of beauty, temperament, and manageable size, making it a highly rewarding species for dedicated keepers
