The animal kingdom is split into five infrakingdoms/superphyla, specifically Porifera, Ctenophora, Placozoa, Cnidaria and Bilateria. Most living animal species belong on the infrakingdom Bilateria, a highly proliferative clade whose customers Have got a bilaterally symmetric and substantially cephalised system strategy, plus the vast majority of bilaterians belong to two substantial superphyla: the protostomes, which includes organisms for example arthropods, molluscs, flatworms, annelids and nematodes; as well as deuterostomes, which consist of echinoderms, hemichordates and chordates, the latter of which has the vertebrates. The much more compact basal phylum Xenacoelomorpha have an unsure posture inside Bilateria.
