What are the classification of phylum Porifera?
calcareous sponges
The phylum Porifera has four classes, namely the Calcarea, Demospongiae, Hexactinellida and Homoscleromorpha. Exclusively marine, calcareous sponges predominantly inhabit shallow tropical waters.
What is the main characteristic used to classify sponges?
Sponges are the simplest multicellular organisms, classified by their primitive cellular-level of organization, their porous bodies, and their filter-feeding system. Sponges have specialized cells that can carry out distinct functions within the organism.

- Water canal (aquiferous) system.
- Organic and inorganic skeletons.
- Totipotency. Plasticity.

- They are diploblastic animals with two layers, the outer dermal layer and the inner gastral layer.
What are the characteristics of sycon?
Sycon ciliata are creamy yellow in color and delicate-looking. Their bodies are arranged in the asconoid system, which is a simple tube with no folding of the outer body wall. They range from 1-3cm in height. Hairy, needle-like spines (called spicules) cover their bodies.

What are members of phylum Porifera commonly called?
Sponges, the members of the phylum Porifera (/pəˈrɪfərə/; meaning “pore bearer”), are a basal Metazoa (animal) clade as a sister of the Diploblasts. They are multicellular organisms that have bodies full of pores and channels allowing water to circulate through them, consisting of jelly-like mesohyl sandwiched between two thin layers of cells.
