    • arthropoda One of two prime divisions (Anarthropoda being the other) into which a subkingdom Annulosa has been divided. It contains bilateral segmented animals with articulated legs, and approximately corresponds to the “articulated animals with articulated legs” of Cuvier, as contrasted with his other division (Annelides) of Articulata, or with the Condylopoda of Latreille, or with the Gnathopoda or Arthrozoa of some other naturalists.
    • arthropoda In more modern and exact usage, one of the phyla, subkingdoms, or main types of the Metazoa, containing the articulated, invertebrate, non-ciliated animals with articulated limbs, a ganglionic nervous system, oviparous reproduction, and generally separate sexes. The phylum is divided by nearly common consent into the four great classes Insecta, Myriapoda, Arachnida, and Crustacea, and contains the vast majority (about four fifths) of the animal kingdom, in numbers both of species and of individuals.
