How many pairs of legs do arachnids possess?

Arachnids are a class of joint-legged invertebrates that include spiders, scorpions, ticks, and mites. A defining characteristic of arachnids is that they possess eight legs, which distinguishes them from insects, which have six legs. This octopodous feature is essential for their mobility and is a fundamental aspect of their anatomy. The eight legs play crucial roles in locomotion, sensing the environment, and capturing prey. Recognizing this trait helps differentiate arachnids from other arthropod groups and provides insight into their evolutionary adaptations. Understanding the leg count also assists in identifying various species within this diverse class.
