The ecdysozoan clade Panarthropoda includes the following phyla:
B) Tardigrada - These are also known as water bears or moss piglets. They are very small, water-dwelling, segmented micro-animals with eight legs.
D) Onychophora - Commonly known as velvet worms, they have a wormlike body with multiple pairs of stubby, unjointed appendages.
Phylum Annelida, which includes segmented worms like earthworms and leeches, is not part of the Panarthropoda clade but belongs to the Lophotrochozoa clade. Phylum Nematoda, which includes roundworms, is part of the Ecdysozoa superphylum but not the Panarthropoda clade. Therefore, the correct answers are B) Tardigrada and D) Onychophora.
