Panarthropoda
Animal taxon / From Wikipedia, the free encyclopedia
Panarthropoda is a proposed animal clade containing the extant phyla Arthropoda, Tardigrada (water bears) and Onychophora (velvet worms).[3] Panarthropods also include extinct marine legged worms known as lobopodians ("Lobopodia"), a paraphyletic group where the last common ancestor and basal members (stem-group) of each extant panarthropod phylum are thought to have risen.[4][5][6][7][8][9] However the term "Lobopodia" is sometimes expanded to include tardigrades and onychophorans as well.[5]
