## Quick answer

The boa constrictor (Boa constrictor) is a large, heavy-bodied, non-venomous snake native to tropical forests, savannas, and deserts across Central and South America. It typically reaches 2 to 3 m and weighs around 10 to 15 kg, killing prey not with venom but by coiling around it and squeezing until it can no longer breathe. A slow-moving ambush hunter, the boa can live 20 to 30 years and is listed as Least Concern.

## Size and appearance

The boa constrictor is a thick, muscular snake that commonly grows to 2 to 3 m, with females larger than males and weighing up to around 15 kg. Its background colour ranges from tan and brown to grey, overlaid with distinctive dark saddle-shaped markings that deepen to reddish tones towards the tail, giving rise to the nickname red-tailed boa. This patterning is superb camouflage among leaf litter and dappled forest light. Unlike venomous snakes, it has a narrow head only slightly wider than its neck and no fangs.
