Boidae is a family of non-venomous snakes commonly known as boas. They are found in various habitats, including tropical rainforests, deserts, and grasslands across the Americas, Africa, and some islands. Boas are known for their large size, with some species, like the Green Anaconda, being among the heaviest snakes in the world. They are constrictors, meaning they subdue their prey by wrapping around it and suffocating it. Boidae includes several genera, such as Boa and Epicrates. These snakes typically have a robust body and can vary in color and pattern, which helps them blend into their environment. Boas are also known for their ability to give birth to live young, a trait that distinguishes them from many other snake families that lay eggs.
