Panarthropoda

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
• segmented body
