There are 25 known species of pythons in the world. Like all snakes, pythons are cold blooded. Pythons are not venomous; they kill their prey by constriction. Some of the different types of pythons are the reticulated python, the ball python, the Burmese python, the green tree python, and the carpet python. While some of these species should not be held captive by a non-professional, other types of pythons can make good pets.
The longest Python? The longest python on record was a reticulated python that reached a length of 10.1 meters. While it was common to find individuals with lengths up to 8 meters in the wild only a few decades ago, few wild creatures today exceed 5 to 6 meters.here are many big snakes in the world. There is no way to define what a giant snake is except that its bigger than most snakes. Most snakes are no larger than 1.25 meters.
