Boa Constrictor
Boa constrictor
Quick answer
The boa constrictor is a large, non-venomous snake found from Mexico through Central and South America, typically reaching 2 to 3 m (6.5 to 10 ft) long. It kills prey by constriction, wrapping its muscular body around an animal until it can no longer breathe. Boas are popular pet snakes thanks to their generally calm nature and can live 20 to 30 years.

Where it lives
Tropical forests, savannas, and deserts from Mexico through Central and South America.
Behavior and constriction
Boa constrictors are mostly nocturnal ambush hunters that wait in cover for prey to pass. They strike, grip with their teeth, and quickly throw coils around the animal, squeezing tighter each time it exhales until it can no longer breathe. They are good climbers and swimmers but spend much of their time on or near the ground.
Diet and feeding
These snakes are carnivores that eat birds, bats, lizards, and a wide range of mammals from rodents up to small wild pigs. They swallow prey whole, head first, and their slow metabolism means a large meal can sustain them for weeks. Heat-sensitive scales help them detect warm-blooded prey in darkness.
Habitat and range
Boa constrictors range from northern Mexico through Central America and across much of South America. They are highly adaptable, living in tropical rainforest, dry forest, savanna, and even semi-desert and farmland. They often shelter in burrows or hollow logs left by other animals.
As a pet
Boa constrictors are among the most commonly kept large pet snakes because they are generally docile and long-lived. They need a secure, heated enclosure with room to grow, as adults can reach several meters and become quite heavy. Their long lifespan makes them a serious, decades-long commitment.
