The term DEADLY REPTILES can be summarized by the four letter acronym ASPS, which stands for 'Antilion, Snakes, Pythons, and Scorpions'. These four animals are all considered to be some of the most dangerous reptiles in the world. Antilions are large predatory insects found in sandy habitats, while snakes, pythons, and scorpions are all venomous creatures that can cause serious harm to humans.
