They are not venomous, and many do not live in jungles. That’s probably because these big snakes make a big impression! But boas are usually pretty quiet and calm and don’t deserve their nasty reputation. Not the bad guys. Boas often appear in movies and stories that take place in the jungle, usually as the villain sliding menacingly through the trees. One of the biggest differences is that pythons lay eggs while boas give birth to live young, although some sand boas and the Round Island boa of Mauritius lay eggs. Pythons have one more bone in their head than boas do and some additional teeth, and pythons are found in Africa, Asia, and Australia while boas live on those continents as well as North, Central, and South America. These snakes have some things in common: they are constrictors, killing their prey by wrapping around it and suffocating it, and they are considered primitive snakes with two lungs (most snakes have only one) and remnants of hind legs and pelvic bones.īut they have differences, too. That leaves two groups, the boas and the pythons. The first thing to note is that the anaconda is a kind of boa, not a separate type of snake. Boas, pythons, and anacondas: What's the difference? Because boa constrictors, reticulated pythons, and anacondas are some of the biggest snakes in the world, many people get confused about which is which.
