The platypus and spiny anteater (echidna) are included in the group monotremata (meaning they pass gametes, feces, and urine through one cloacal sphincter. Marsupials include kanagaroos and possoms. Placentals include all placental animals (eutheria). Hominids are of the hominidae family in the primate order.
Invertebrate chordates including the tunicates and sea squirts (Urochordata) and lancelets (Cephalochordata) are filter feeders.
Chordates: do have a pharynx or pharynx pouches, notochord, nerve cord, but have a TRUE coelom
Urochordata is a subphylum of chordata including sea squirts and tunicates. Hemichordata is a phylum including acorn worms. Cephalochordata is a subphyum of chordata including lancelets. Vertebrata is a subphylum of chordata.
