Habitat & Range
Native to the tropical forests of Central and South America, boa constrictors prefer warm, humid environments. As a capable swimmer, they are also found along rivers and streams. They are mainly terrestrial and commonly live in hollow logs and abandoned mammal burrows.
Depending on location and available prey, boa constrictors can reach lengths anywhere from 3 to 13 feet. They are heavy-bodied, with the largest specimens reaching up to 60 pounds. Scales are usually brown, gray or cream in base color with red-brown spots that are more pronounced near the tail.
Boa constrictors prey on a variety of small to medium sized mammals and birds. The bulk of their diet consists of rodents and lizards. Young boa constrictors feed on mice, birds, bats and amphibians.
Reproduction & Lifespan
Mating takes place during the dry season, which usually occurs between April and August. The female bears live young, and can produce as many as 64 young in one cycle. Gestation lasts for up to 150 days, during which time the female does not consume any food.
Fantastic Fact Feel the Warmth
Boa constrictors have poor vision, and therefore rely their specialized heat-sensing cells to locate prey.
