The approximately 8,550 living sponge species are scientifically classified in the phylum Porifera, which is comprised of four distinct classes: the Demospongiae (the most diverse, containing 90 percent of all living sponges), Hexactinellida (the rare glass sponges), Calcarea (calcareous sponges), and Homoscleromorpha …
What is the common name for a sponge?

What are spicules and spongin?
Spongin is a modified type of collagen protein, and forms the “fibers” or “mortar” that hold spicules together. Spicules are the structural components of a sponge, or the “bricks,” and the shapes, sizes, and composition are unique for each species.
What is parazoa and Eumetazoa?
Eumetazoa are animals whose tissue are organized into true tissues and there is a development of organs. Parazoa lack this tissue organization. This signifiies that eumetazoa have more complexly organized tissue than parazoa do. Examples of parazoa belong to phylum porifera, or sponges.
What are the 4 main types of cells found in sponges?
Although sponges do not have organized tissue, they depend on specialized cells, such as choanocytes, porocytes, amoebocytes, and pinacocytes, for specialized functions within their bodies.

Are gymnosperms a monophyletic group?
This also leaves us with the peculiar conclusion that the Gymnosperms are a monophyletic group, but the conifers are not! Some authorities remain sceptical of the gnepine hypothesis, noting the general lack of morphological support for it.
How many species of gymnosperms are in Wisconsin?
