The term POISONOUS CREATURES can be summarized by the four letter acronym ASPS, which stands for 'Arthropods, Snakes, Spiders, and Scorpions'. These creatures are all venomous and can cause serious harm to humans if they are not handled properly. Arthropods include insects, spiders, and centipedes, while snakes, spiders, and scorpions are all members of the arachnid family. All of these creatures have evolved to produce toxins that can be used to defend themselves or to capture prey.
