Sponges or sea sponges are primarily marine invertebrates of the metazoan phylum Porifera [4] (/ p ə ˈ r ɪ f ər ə ˌ p ɔː-/ pər-IF-ər-ə, por-; meaning 'pore bearer'), [5] a basal animal clade and a sister taxon of the diploblasts. [6]
Using their ostia and osculum these sponges filter the water for various small aquatic organisms such as protozoans, bacteria, and other free-floating pond life. [4] Sponges of the genus Spongilla partake in symbiotic relationships with green algae, zoochlorellae. The symbiotic zoochlorellae give the sponges a green appearance and without them ...
Porifera (sponges), multicellular organisms that have bodies full of pores and channels allowing water to circulate through them; Priapulida, or penis worms, are a phylum of marine worms that live marine mud. They are named for their extensible spiny proboscis, which, in some species, may have a shape like that of a human penis;

In addition to this, a sponge disease caused by pathogenic bacteria and fungi has further reduced populations. [3] The bacteria and fungi destroy tissues and fibers of the sponges, making them weak. [3] Due to the regenerative abilities of these sponges, they are able to set aside infected tissue and recover. [3]
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 ...
All three sponge body plans (asconoid, syconoid, and leuconoid) can be found within the class Calcarea. Typically, calcareous sponges are small, measuring less than 10 cm (3.9 in) in height, and drab in colour. However, a few brightly coloured species are also known. Like the Homoscleromorpha, calcareous sponges are exclusively viviparous. [7]
Many organism such as crustaceans and worms are typical organisms found within the sponge. [8] These sponges are a great habitats to sustain other kinds of life. Hippospongia communis has a bioactive compound that makes it anti-fungal. This is due to untensopongin B, making the sponge perfect for its uses in old medicine. [2] [6]
