Boa constrictors are native to Central and South America. They live in tropical regions, and although they are able to swim, they spend most of their time on dry land. Boa constrictors build their nests in hollow logs or underground burrows that have been abandoned by the mammals who built them.
Boa constrictors are a large species of snake with an average weight of 60 pounds. They measure around 13 feet long when mature. Although they are not venomous, they are feared by humans because of their ability to wrap themselves tightly around prey, suffocating and crushing it to death. Boas eat small prey, such as mice and lizards, when they are young. As they age and grow larger, they begin eating larger animals, such as monkeys, birds and pigs. They swallow their prey whole, stretching their jaws open to accommodate it. The prey sits in their digestive tract for four to six days, slowly being digested by digestive juices.
Boa constrictors are sometimes kept in captivity by zoos and private collectors. They can be fed small mice when they are small and larger rats once they reach adulthood. For safety reasons, boas must be kept in secure glass terrariums. Male boas must be kept separate from each other because housing them together may cause a fight. However, two females can be housed together. Boas regularly live up to 30 years in captivity, making owning one a major commitment.
