Although spiders and insects are both arthropods, they belong to different taxonomic groups. Spiders are arachnids, related to scorpions, ticks, and mites. Unlike insects, which have six legs and three main body sections (head, thorax, and abdomen), spiders have eight legs and two main body sections (cephalothorax and abdomen). Spiders also lack antennae and possess specialized silk-producing organs called spinnerets.
