How many legs do arachnids have?

Arachnids are a class of joint-legged invertebrates that are characterized by having eight legs. This group includes well-known creatures such as spiders, scorpions, ticks, and mites. Unlike insects, which have six legs, arachnids have developed two additional pairs of legs, which contribute to their distinctive movement and predatory capabilities. The anatomical structure and function of their eight legs allow them to navigate their environment effectively, capture prey, and defend against predators. This eight-legged feature is a defining characteristic that separates arachnids from other arthropods. Understanding this fundamental biological trait is essential in differentiating arachnids from other groups of animals with varying leg counts.
