Pythons are oviparous. This sets them apart from the family Boidae (boas), most of which bear live young (ovoviviparous). After they lay their eggs, females typically incubate them until they hatch. This is achieved by causing the muscles to “shiver”, which raises the temperature of the body to a certain degree, and thus that of the eggs. Keeping the eggs at a constant temperature is essential for healthy embryo development. During the incubation period, females do not eat and leave only to bask to raise their body temperature.
The world’s longest snake, the reticulated python, is also part of the Pythonidae family. All of the species within this family are non-venomous. … But no, pythons are not poisonous / venomous in any way that could harm humans. They kill their prey by slowly squeezing it to death.
