Porifera. Sponges (Phylum Porifera) are a group of simple aquatic invertebrates that include three groups – Glass sponges, Demosponges and Calcareous sponges. There are about 5,000 to 10,000 species of sponges found mostly in marine environments with about 100 species of freshwater sponges.

10 Sea Sponges Facts You Didn’t Know About
- Sea Sponges are animals, not plants.
- Sea Sponges have been in the ocean for 500 million years.
- Sea Sponges don’t move, but they filter lots of water for food (plankton) and oxygen.
- Sea Sponges are among the most simple of multi-cellular organisms.
What is the importance of Porifera?
They play key roles in important biogeochemical cycles such as nitrogen and carbon and also in bentho-pelagic coupling. Sponges also believed to establish an amazing sink for silicon and grazed carbon.
What are the 3 types of 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). Sponges are characterized by the possession of a feeding system unique among animals.
Is SpongeBob an animal?

What are Porifera used for?
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.
What is Porifera habitat?
The phylum Porifera comprises the sponges. Sponges are simple invertebrate animals that live in aquatic habitats. Although the majority of sponges are marine, some species live in freshwater lakes and streams. They are found in shallow ocean environments to depths as great as five kilometers (km).
What makes a sponge an animal?
Yes, sea sponges are considered animals not plants. But they grow, reproduce and survive much as plants do. They have no central nervous system, digestive system or circulatory system – and no organs! Sea sponges are one of the world’s simplest multi-cellular living organisms.
How do Poriferans reproduce?
Sponges reproduce by both asexual and sexual means. Most poriferans that reproduce by sexual means are hermaphroditic and produce eggs and sperm at different times. Sperm are frequently “broadcast” into the water column.
How many Porifera are there?
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 are characteristics and examples of Porifera?
Characteristics of Porifera • An example of porifera is Sycon (sponges). Almost all sponges are marine. • Sponges are sessile multicellular organisms, they are permanently attached to rock or sea bed, they obtain food by extracting plankton from water. • Some sponges are tiny, no more than a few millimetres across, but some may reach two metres or more in diameter.
What are the different types of Porifera?

What are some species of Porifera?
Three examples of Porifera include Class Hexactinellida, or glass sponges, Class Calcarea, which which are sponges that have spicules composed of calcium carbonate, and Class Demospongia, which are the most common type of sponge and its spicules are primarily composed of spongin. Class Homoscleromorpa is yet another example of porifera.
