The animal kingdom is divided into five infrakingdoms/superphyla, specifically Porifera, Ctenophora, Placozoa, Cnidaria and Bilateria. Most residing animal species belong towards the infrakingdom Bilateria, a extremely proliferative clade whose customers Have a very bilaterally symmetric and substantially cephalised system plan, as well as the overwhelming majority of bilaterians belong to 2 significant superphyla: the protostomes, which includes organisms like arthropods, molluscs, flatworms, annelids and nematodes; as well as the deuterostomes, which include things like echinoderms, hemichordates and chordates, the latter of which incorporates the vertebrates. The much smaller sized basal phylum Xenacoelomorpha have an uncertain placement in Bilateria.

When invertebrates exhibit an array of system programs and buildings, vertebrates have a more standardized human body plan due to their shared backbone framework.
Aristotle was uncertain whether sponges were being animals, which in his system ought to have sensation, urge for food, and locomotion, or vegetation, which did not: he realized that sponges could sense touch and would deal if going to be pulled off their rocks, but that they had been rooted like crops and never ever moved about.[157]
