- Arachnids — An alternative spelling variant for arahnide (arachnids); a major class of terrestrial or aquatic chelicerate arthropods, characterized by a body segmented into a cephalothorax and abdomen, the lack of antennae, the presence of two pairs of mouth appendages (chelicerae and pedipalps), and exactly eight articulated legs. The class includes spiders, scorpions, harvestmen, mites, and ticks, playing a vital ecological role as insect predators.
- Arachnologist — A woman who specializes in arachnology; a female biologist or zoologist dedicated to the scientific and methodical study of organisms within the class Arachnida, such as spiders, scorpions, mites, and harvestmen. Her activity encompasses field work for collecting specimens, laboratory taxonomic analysis, describing new species, and studying the ecological or biochemical impact of these invertebrates venoms.
- Arachnology — A specialized branch of zoology that deals with the scientific, systematic, and methodical study of organisms classified within the class Arachnida, including spiders, scorpions, harvestmen, and mites. Unlike entomology, which analyzes insects, this discipline focuses on the structural biology, phylogenetic taxonomy, behavioral ecology, and biochemical properties of venoms and silks specific to terrestrial chelicerates.
