What is phylum Porifera common name?

What are the four classes of Porifera?
The phylum Porifera has four classes, namely the Calcarea, Demospongiae, Hexactinellida and Homoscleromorpha. Exclusively marine, calcareous sponges predominantly inhabit shallow tropical waters.
Do any animals eat sponges?

Where are phylum porifera found?
The phylum Porifera comprises the sponges. Sponges are simple invertebrate animals that live in aquatic habitats. Although the majority of sponges are marine, some species live in freshwater lakes and streams. They are found in shallow ocean environments to depths as great as five kilometers (km).
What are some ways to describe phylum Porifera?
There are following characteristics of the phylum Porifera: Their bodies consist of loosely organized cells. They vary in size from less than a centimeter to a mass that can fill your arm. They are asymmetrical or radially symmetrical. They have three cell types: pinacocytes, mesenchyma cells, and choanocytes. They have central cavity or spongocoel. Numerous pores are present in the body wall.
What are characteristics and examples of Porifera?

What are the major classes of Porifera phyla?
– Calcarea. They live in marine, shallow, and coastal water. Choanocytes appear as conspicuously large cells. – Hexactinellida. They live in the marine and the deep sea. Its comprises a six-rayed siliceous spicule skeleton, build of silicon. – Desmospongia. They live in marine or freshwater. The body is asymmetrical.
What are the types of phylum?
In biology, a phylum is a division of organism (taxonomic rank) below kingdom (such as Animalia ) and above class (such as Mammalia ). There are 38 animal phyla, with nine phyla — Mollusca, Porifera, Cnidaria, Platyhelminthes, Nematoda, Annelida, Arthropoda, Echinodermata, and Chordata — making up the vast majority of all animals.
