The animal kingdom is split into 5 infrakingdoms/superphyla, namely Porifera, Ctenophora, Placozoa, Cnidaria and Bilateria. Most residing animal species belong on the infrakingdom Bilateria, a very proliferative clade whose associates Possess a bilaterally symmetric and appreciably cephalised overall body strategy, and also the vast majority of bilaterians belong to two significant superphyla: the protostomes, which incorporates organisms including arthropods, molluscs, flatworms, annelids and nematodes; and also the deuterostomes, which incorporate echinoderms, hemichordates and chordates, the latter of which includes the vertebrates. The much scaled-down basal phylum Xenacoelomorpha have an uncertain place inside of Bilateria.
