Panarthropoda is a taxon combining the phyla Arthropoda, Tardigrada, and Onychophora.[1] Not all studies support it,[2] but most do, including neuroanatomical,[3] mitogenomic[4] and palaeontological[5] studies. Originally, they were considered to be closely related to the annelids, grouped together as the Articulata, but newer studies place them among a the Ecdysozoa.

Common characteristics of the Panarthropoda include the presence of legs and claws, a ventral nervous system, and a segmented body.
