Description of the Species
Arachnids are a class (Arachnida) of joint-legged invertebrate animals in the subphylum Chelicerata. All arachnids have eight legs, although in some species the front pair may convert to a sensory function. The term arachnid is from the Greek word άράχνη or arachne, meaning spider, and also referring to the mythological figure Arachne.
Most arachnids are terrestrial. However, some inhabit freshwater and marine environments as well. They comprise over 100,000 named species, including spiders, scorpions, harvestmen, ticks, and mites.
