Classification. Diagnostic features. Animals are multicellular eukaryotes whose cells are bound together by collagen. They have sperm and form polar bodies in oogenesis. Animals lack semirigid cell walls, and movement is effected through muscle and nerve cells. They usually gain energy from other organisms or their products.
In biology, taxonomic rank is the relative level of a group of organisms (a taxon) in an ancestral or hereditary hierarchy. A common system of biological classification ( taxonomy) consists of species, genus, family, order, class, phylum, kingdom, and domain.
The following is a list of the classes in each phylum of the kingdom Animalia. There are 107 classes of animals in 33 phyla in this list. However, different sources give different numbers of classes and phyla. For example, Protura, Diplura, and Collembola are often considered to be the three orders in the class Entognatha.
