The animal kingdom is split into five infrakingdoms/superphyla, namely Porifera, Ctenophora, Placozoa, Cnidaria and Bilateria. Most living animal species belong into the infrakingdom Bilateria, a extremely proliferative clade whose customers Possess a bilaterally symmetric and noticeably cephalised physique prepare, and also the overwhelming majority of bilaterians belong to two large superphyla: the protostomes, which incorporates organisms including arthropods, molluscs, flatworms, annelids and nematodes; as well as the deuterostomes, which consist of echinoderms, hemichordates and chordates, the latter of which has the vertebrates. The Considerably scaled-down basal phylum Xenacoelomorpha have an unsure posture inside of Bilateria.
