The animal kingdom is divided into 5 infrakingdoms/superphyla, particularly Porifera, Ctenophora, Placozoa, Cnidaria and Bilateria. Most dwelling animal species belong into the infrakingdom Bilateria, a extremely proliferative clade whose users Possess a bilaterally symmetric and drastically cephalised entire body strategy, and the overwhelming majority of bilaterians belong to two large superphyla: the protostomes, which incorporates organisms such as arthropods, molluscs, flatworms, annelids and nematodes; as well as the deuterostomes, which incorporate echinoderms, hemichordates and chordates, the latter of which contains the vertebrates. The Substantially scaled-down basal phylum Xenacoelomorpha have an unsure position within just Bilateria.
