Boa Constrictor

The boa constrictor is a large, non-venomous snake native to a wide range of habitats across Central and South America, from tropical rainforest to semi-arid scrub. It kills prey by constriction, coiling its muscular body around an animal after striking and tightening with each breath the prey takes until circulation stops, before swallowing its meal whole; its diet ranges from birds and rodents to larger mammals depending on the snake's size. Coloration and pattern vary widely across its many recognized subspecies and regional populations, typically featuring dark saddle-shaped blotches over a brown, grey or reddish background that provides effective camouflage in leaf litter. Boa constrictors are ambush predators that spend much of their time motionless, relying on heat-sensitive pits near the mouth to detect warm-blooded prey in low light, and they are capable swimmers and climbers despite their heavy build. Long popular in the exotic pet trade due to their manageable size and generally calm temperament compared to other large constrictors, the species remains widespread and is not currently considered threatened.
