Calcareous sponges (Phylum Porifera, Class Calcarea) are known to be taxonomically difficult. The invertebrates, or invertebrata, are animals that do not contain bony structures, such as the cranium and vertebrae.The simplest of all the invertebrates are the Parazoans, which include only the phylum Porifera: the sponges ().Parazoans (“beside animals”) do not display tissue-level organization, although they do have specialized cells that perform specific functions. The phylum Porifera consists mainly of marine sponges. Asexual and Sexual Reproduction Genetically identical cells are produced from a single parent cell by mitosis. Major Characteristics: • Feed by filtering water through their outer walls and pumping it out of the body. PoriferaCalcarea - These have skeletons made of Calcite. There are about 300 Species. ...Hexactinellida (Hyalospongiae) - They are also known as Glass Sponges.
