Poriferans, commonly known as sponges, primarily inhabit marine environments, particularly in shallow coastal waters. However, some species can also be found in freshwater habitats. They typically attach to substrates like rocks, coral reefs, or other surfaces, thriving in various ecological niches where they filter water for food and oxygen.

A Poriferan typically consists of two cell layers: the outer epidermis and the inner layer of cells called choanocytes. These cells are separated by a gel-like matrix called mesohyl.
Corals are animals of the phylum Cnidaria, whereas:-Sponges are animals of the phylum Porifera.
The control surface on a Poriferan is the surface that lines its internal canals and chambers. This surface is covered in specialized cells called choanocytes, which have flagella that create water currents to draw in food particles and oxygen for the sponge. The control surface plays a crucial role in nutrient exchange and waste removal in Poriferans.
ventral When dealing with Porifera, any questions concerning the head is immediately answered with the question: 'What head?'
An asymmetrical animal without tissues or organs is called a "poriferan," commonly known as a sponge. Sponges belong to the phylum Porifera and are simple aquatic organisms characterized by their porous bodies and lack of true tissues and organs. They rely on the flow of water through their bodies to obtain nutrients and oxygen, and to remove waste.
