Pythons are nonvenomous constrictor snakes, which wrap their long bodies around their prey and gradually squeeze the breath out of them. They are capable of unhinging their jaws and swallowing much larger prey than would seem possible. They are the longest snakes in the world, with one species even reaching a recorded length of 10m (33 feet). Although they are quite slim they can weigh up to 130 kg. Pythons mostly come in grey, white, black and yellow colors with the reticulated python having a netlike pattern. Unfortunately pythons are often killed for their skins, but they are not yet considered endangered.
