What are the 4 classes of sponges?
The classification of sponges is based on spicule form and chemical composition. Living sponges have traditionally been divided into three or perhaps four classes: Homoscleromorpha, Calcispongiae, Hexactinellida, and Demospongiae.
What is special about Calcarea sponges?
Memebers of the group Calcarea are the only sponges that possess spicules composed of calcium carbonate. These spicules do not have hollow axial canals. The Calcarea first appears at the base of the Lower Cambrian and has persisted until the present.
How do calcareous sponges reproduce?
In Calcareous sponges, reproduction can be both sexual and asexual, by budding. The eggs hatch to free swimming larvae, which attach themselves to the bottom after a few days. In the case of budding, the sponges produce a cluster of cells known as a gemmule that is covered in a hard coating.

What are the two basic types of sponges?
Encrusting and Freestanding are two basic types of sponges. Water regulates into sponge’s body through their pores with the help of the beating of flagella.
What are the 3 body types of sponges?
Sponges have three body types: asconoid, syconoid, and leuconoid. Asconoid sponges are tubular with a central shaft called the spongocoel. The beating of choanocyte flagella forces water into the spongocoel through pores in the body wall.
