True Animals are grouped into a sub-kingdom called Eumetazoa.  All True Animals have tissues and organs, except for one type called Myxozoa. These have regressed to a single-celled form.

The simplest eumetazons are the Radiata, a loose group that includes jellyfish, corals, and comb jellies.  Most of them belong in the phylum Cnidaria, except for the comb jellies, which comprise the phylum Ctenophora.  Radiatans have what is called radial symmetry, where they can be divided into two even halves in many planes, like a wheel or a circle.  All cnidarians have special cells called cnidocytes, which produce the sting.  Comb jellies have no such cells, and are harmless to humans.
