Spiders belong to the class Arachnida, which is part of the phylum Arthropoda. This class encompasses various eight-legged organisms, including scorpions, ticks, and mites.
Within Arachnida, spiders are further classified into several orders, with the most common being Araneae, which specifically includes all true spiders. Other notable features of spiders include their ability to produce silk, which they use for various purposes such as building webs, making shelters, and catching prey.
Unlike insects, which belong to the class Insecta and have six legs, spiders have eight legs and lack antennae. This distinct anatomical difference helps in classifying them separately from insects. Understanding these classifications helps in the study of biodiversity and the ecological roles that these fascinating creatures play in nature.
