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.
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.
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.
