Kingdom Animalia: Phyla Porifera, Cnidaria, and Ctenophora by Peter Abramoff, Robert G. Thomson, January 1, , W. H. Freeman edition, Paperback in English. Primitive phyla without a true coelom include the Porifera and Coelenterata (Cnidaria). Animal phyla are classified according to certain criteria, including the type of coelom, symmetry, body plan, and presence of segmentation. Sponges (Porifera) have a primitive cellular level of .
A phylum is the taxonomical rank below kingdom and above class. The kingdom Animalia contains approximately 40 phyla. Organisms are grouped into phyla based on a general body plan. For example. Kingdom animalia is divided into two sub kingdoms-Parazoa (cellular level) and Eumetazoa (tissue level) Subkingdom Parazoa includes the Phylum Porifera. Subkingdom Eumetazoa includes all the Phyla from coelenterates to chordates. Animals are multicellular eukaryotic organisms that form the biological kingdom Animalia. With few exceptions, animals consume organic material, breathe oxygen, are able to move, can reproduce sexually, and grow from a hollow sphere of cells, the blastula, during embryonic development. Over million living animal species have been described—of which around 1 million are . One of the major divisions of living things; the second-largest standard unit of biological classification. Arthropods and molluscs are examples of phyla. Phyla in the plant kingdom are frequently.
Kingdom Animalia includes all organisms that develop from a hollow ball of cells called a blastula. Most animals have well-developed motility. The simplest animals include the sponges (Porifera) and the Cnidaria. Sponges are unsymmetrical or radially symmetrical, with many cell types but no distinct tissues; their bodies contain numerous pores and sharp protective spicules.

Figure Broad classification of Kingdom Animalia based on common. Organisms in Kingdom Animalia are classified into different phylum including Porifera, Cnidaria, Ctenophora, Platyhelminthes, Aschelminthes, Annelida, Arthropoda, Mollusca, Echinodermata, Hemichordata, and Chordata.
