Together with scorpions, ticks and mites, spiders are part of a group called arachnids. They are not insects. The body of an arachnid is divided into two parts, while the body of an insect is in three sections. Arachnids have four pairs of walking legs, while insects have three pairs. Spiders are the most common members of this group of arthropods, and they are all carnivores. They capture their prey in webs or by running after them, paralyzing them by injecting poison from their jaws. Spiders cannot swallow solid food; instead they inject digestive juices into their prey, which liquefy it. They are then able to suck in the digested food through their jaws.
