The animal kingdom is divided into 5 infrakingdoms/superphyla, particularly Porifera, Ctenophora, Placozoa, Cnidaria and Bilateria. Most dwelling animal species belong towards the infrakingdom Bilateria, a highly proliferative clade whose users Have a very bilaterally symmetric and noticeably cephalised system prepare, along with the overwhelming majority of bilaterians belong to two huge superphyla: the protostomes, which includes organisms such as arthropods, molluscs, flatworms, annelids and nematodes; along with the deuterostomes, which contain echinoderms, hemichordates and chordates, the latter of which contains the vertebrates. The Significantly more compact basal phylum Xenacoelomorpha have an uncertain place in just Bilateria.
