A boa is a type of non-venomous snake belonging to the family Boidae. These snakes are known for their large size and distinctive patterns, which can vary widely among species. Boas are primarily found in tropical regions of the Americas, but some species inhabit other areas as well. They are constrictors, meaning they subdue their prey by wrapping around it and squeezing until it suffocates. Boas are often kept as pets due to their docile nature and striking appearance. They can grow to impressive lengths, with some species reaching over 10 feet. In the wild, they typically feed on small mammals, birds, and reptiles, using their keen sense of smell to locate food.
