A boa is a type of large, non-venomous snake belonging to the family Boidae. These snakes are known for their distinctive method of constriction, where they wrap around their prey and squeeze until it suffocates. Boas are found in various habitats, including tropical rainforests, deserts, and grasslands, primarily in Central America, South America, and the Caribbean. Boas can vary in size, with some species growing over 13 feet long. They have a diverse diet, feeding on small mammals, birds, and reptiles. Common species include the Boa constrictor, which is often kept as a pet, and the Emerald tree boa, known for its striking green color.
