Panarthropoda is a taxon combining the phyla Arthropoda, Tardigrada and Onychophora. Originally, they were considered to be closely related to the annelids, grouped together as the Articulata, but newer studies place them among a group called the Ecdysozoa.
Common characters of the Panarthropoda include:
- presence of legs
- presence of claws
- ventral nervous system (see also ventral, nervous system)
- segmented body
