The scientific name Porifera is a neuter plural of the Modern Latin term porifer, which comes from the roots porus meaning "pore, opening", and -fer meaning "bearing or carrying". Overview Sponge biodiversity and morphotypes at the lip of a wall site in 60 feet (20 m) of water.
Amphimedon compressa can grow to a length of 40 cm (16 in) and a diameter of 4 cm (1.6 in), but it is usually smaller in shallow water. The tree-like curved branches grow from a basal encrusting mass, but very occasionally this sponge grows as a small, unbranched, flattened hemisphere.
Porifera are suspension feeders, meaning they can filter plankton and other microorganisms through its osculum. Porifera contain choanocytes , pinacocytes , and archeocytes . The structure of the choanocyte being a singular flagellum surrounded by microvilli is a characteristic of most porifera which allows water to enter.
Demosponges (Demospongiae) are the most diverse class in the phylum Porifera. They include greater than 90% of all species of sponges with nearly 8,800 species worldwide (World Porifera Database). [5] They are sponges with a soft body that covers a hard, often massive skeleton made of calcium carbonate, either aragonite or calcite [citation ...
Spongilla lacustris is part of the class demosponges of the phylum Porifera. The Porifera phylum contains all sponges which are characterized by the small pores on the outer layer, which take in water. The cells in the sponge walls filter food from the water. Whatever is not uptaken by the sponge is pumped through the body out of a large opening.
The calcareous sponges [2] [3] (class Calcarea) are members of the animal phylum Porifera, the cellular sponges. They are characterized by spicules made of calcium carbonate, in the form of high-magnesium calcite or aragonite. While the spicules in most species are triradiate (with three points in a single plane), some species may possess two ...
Cliona celata, occasionally called the boring sponge, is a species of demosponge belonging the family Clionaidae. [1] It is found worldwide. This sponge bores round holes up to 5 millimetres (0.20 in) in diameter in limestone or the shells of molluscs, especially oysters.
Spongia officinalis, better known as a variety of bath sponge, is a commercially used sea sponge. [2] Individuals grow in large lobes with small openings and are formed by a mesh of primary and secondary fibers.
