![]() Pythons can be difficult to find and watch long enough to learn their habits. If threatened, some pythons roll into a ball and tuck their head in the coils others may try to escape, get into a striking, or “S”-shaped, position, or use their constricting power if grabbed. The snakes are most vulnerable after a large meal, when they are less inclined to move quickly. But adult pythons are also at risk from birds of prey and even lions and leopards. Pythons have predators. Small, young pythons may be attacked and eaten by a variety of birds, wild dogs and hyenas, large frogs, large insects and spiders, and even other snakes. But since they don’t have to chase their food, they don’t really need to move quickly. ![]() Pythons can’t move very fast though-only about 1 mile per hour (1.6 kilometers per hour) on open ground. ![]() This type of movement works on the ground as well as in trees. But the biggest difference is that pythons lay eggs while boas give birth to live young.īecause of their bulk, pythons move by traveling forward in a straight line, which is known as "rectilinear progression.” This is accomplished by stiffening the ribs to provide support, then lifting a set of ventral (on the belly) scales and moving them forward so the loose ends grip the surface, pushing the snake ahead. And pythons are found in the Old World (Africa, Asia, Australia) while boas live in both the Old World and the New World (North, Central, and South America). Pythons have one more bone in their head than boas do and some additional teeth. ![]() And they are considered primitive snakes with two lungs (most snakes have only one) and the remnants of hind legs and pelvic bones. These snakes are constrictors, killing their prey by wrapping around it and suffocating it. That leaves two groups: the pythons and the boas. The first thing to note is that the anaconda is a species of boa, not a separate type of snake. None of these huge snakes are venomous or evil. Reticulated pythons, boa constrictors, and anacondas are some of the biggest snakes in the world, and many people get confused about which is which. Pythons, boas, and anacondas: what's the difference? Giant snakes capture our attention as stars of monster movies. ![]()
