Pythons are found in regions like sub-Saharan Africa, Southeast Asia, and Australia, with invasive populations of Burmese pythons in Everglades National Park, Florida and reticulated pythons in Puerto Rico. They are ambush predators that primarily kill prey by constriction, causing cardiac arrest. Pythons are oviparous, laying eggs that females incubate until they hatch. They possess premaxillary teeth, with the exception of adults in the Australian genus Aspidites.[3][4] While many species are available in the exotic pet trade, caution is needed with larger species due to potential danger. The taxonomy of pythons has evolved, and they are now known to be more closely related to sunbeam snakes and the Mexican burrowing python.[citation needed]
