4. Pythons (Pythonidae family)
We are continuing our list of most common non-poisonous snake species in the world with Pythons that are large constrictor snakes spread throughout Africa, Asia, and Australia. There are 31 species and 17 subspecies of pythons currently recognized. Being one of the longest snakes, but also being adapted to various habitats, their body size varies from just 24 inches (like anthill python for example) to 30 feet (reticulated python, also being the longest snake in the world). Pythons inhabit warm climate areas, preferring tropical forests and rainforests, but are also found in other habitats in warm areas. The coloration of pythons depends on their surroundings, since they are nicely camouflaged, being uniformly colored (like olive python) or having nice patterns on the dorsal (backs) side like reticulated pythons or carpet pythons. Pythons are common non-poisonous snakes in America also, because of the great demand for them as pets, but they are often being released in the wild by their owners, where they have adapted nicely especially in warm environments such as Florida.
