2. They are affected by the arrangement of cells, body symmetry, organizational level, coelom, notochord presence/absence, and other factors.
3. The animal kingdom has been divided into 11 phyla based on these characteristics.
4. Some of the most common animal groups include Porifera, Cnidaria, Ctenophora, Aschelminthes, Arthropoda, Nematoda, Annelida, Mollusca, Platyhelminthes, Echinodermata, and Chordata.
