sponge, any of the primitive multicellular aquatic animals that constitute the phylum Porifera. They number approximately 5,000 described species and inhabit all seas, where they occur attached to surfaces from the intertidal zone to depths of 8,500 metres (29,000 feet) or more.
What is a common name for Porifera?
Phylum Porifera (“pori” = pores, “fera” = bearers) are popularly known as sponges.
How do Porifera benefit humans?
Sea sponges are very popular in the health and beauty field. They can be used for cleaning an array of surfaces and have better water retention than that of the artificial sponge. Most popular uses include car care, household cleaning, makeup application and removal, skin exfoliant for when bathing, and personal care.
Which is special feature of Porifera?

Is SpongeBob a Porifera?
Spongebob is not its name, but you can call its scientific name, Porifera, or simply as Sponge. And as their name, Porifera, suggests, these pore bearing creatures filter the sea water for food and nutrients for itself, while releasing the filtered water back into the ocean.
Which sponge body type is most efficient?
Leuconoid body type
Leuconoid body type is the most advanced body form of sponges and is the most efficient circulation system in larger sponges to deliver oxygen and nutrients.
How are sponges beneficial?
Sponges are critical components of the ecosystems of coral reefs, where they provide shelter for a variety of organisms including shrimp, crabs, and algae. They are also a source of food for many sponge-eating fish species. Many sponge species form large colonies or aggregates of individual organisms.
What are sponges useful for?
A sponge is a tool or cleaning aid made of soft, porous material. Typically used for cleaning impervious surfaces, sponges are especially good at absorbing water and water-based solutions. Originally made from natural sea sponges, they are most commonly made from synthetic materials today.
What are some unique characteristics of sponges?
Sponges differ from other animal phyla by their unique possession of 5 distinct features.
- Choanocytes.
- Water canal (aquiferous) system.
- Organic and inorganic skeletons.
- Totipotency.
- Plasticity.
How many species belong to the phylum Porifera?
The approximately 5,000 living sponge species are classified in the phylum Porifera, which is composed of three distinct groups, the Hexactinellida (glass sponges), the Demospongia, and the Calcarea (calcareous sponges).
What organisms belong to the phylum Porifera?
Sponges, the members of the phylum Porifera (/pɒˈrɪfərə/; meaning “pore bearer”), are a basal Metazoa (animal) clade as a sister of the Diploblasts. They are multicellular organisms that have bodies full of pores and channels allowing water to circulate through them, consisting of jelly-like mesohyl sandwiched between two thin layers of cells.
What are the classes found in the Porifera?
The following points highlight the three main classes of Phylum Porifera. The three classes are: 1. Calcarea or Calcispongiae— (Calcareous Sponges) 2. Hexactinellida or Triaxonida or Hyalospongiae—(Glass Sponge) 3. Demospongiae.
Is Porifera an invertebrate or vertebrate?
Scottish Anatomist and Zoologist Robert Edmond Grant proposed the name Porifera (L. Porus, pore and ferre, to bear). The representatives of Phylum Porifera are also known as Sponges. They are simple types of aquatic invertebrates .
