The animal kingdom is divided into 5 infrakingdoms/superphyla, namely Porifera, Ctenophora, Placozoa, Cnidaria and Bilateria. Most residing animal species belong towards the infrakingdom Bilateria, a hugely proliferative clade whose members Have a very bilaterally symmetric and drastically cephalised physique program, and the overwhelming majority of bilaterians belong to 2 huge superphyla: the protostomes, which incorporates organisms like arthropods, molluscs, flatworms, annelids and nematodes; as well as deuterostomes, which contain echinoderms, hemichordates and chordates, the latter of which incorporates the vertebrates. The Significantly lesser basal phylum Xenacoelomorpha have an uncertain placement within Bilateria.
