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 ...
Spongia is a genus of marine sponges in the family Spongiidae, originally described by Carl Linnaeus in 1759, containing more than 60 species. [1] Some species, including Spongia officinalis , are used as cleaning tools, but have mostly been replaced in that use by synthetic or plant material.
These sponges are massive or encrusting in form and have a very simple structure with very little variation in spicule form (all spicules tend to be very small). Reproduction is viviparous and the larva is an oval form known as an amphiblastula. This form is usual in calcareous sponges but is less common in other sponges.
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;

Hippospongia communis also known as the honeycomb bath sponge, is a marine sponge in the phylum Porifera. Hippospongia communis is a brown or darker color [ 1 ] and very porous, due to its many oscules , and is commonly found in shallow waters of the Mediterranean .
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]
