Articulata

 

a term introduced in 1812 by the French zoologist G. Cuvier to designate one of four animal phyla, the other three being Vertebrata, Mollusca, and Radiata. Some modern zoologists use the term to designate the higher segmented proto-stomatic animals, which include Annelida and Arthropoda, as well as the closely related Onychophora, Tardigrada, and Pentastomata.
