Porifera

I arbeidet med Rødlista for svamper er 119 arter vurdert. Dette utgjør omkring en tredel av alle kjente arter i norske farvann. I alt er 28 marine arter og en art fra ferskvann oppført på Rødlista. For marine arter er kunnskapen generelt mangelfull og utilstrekkelig, noe som medfører at en høy andel av rødlisteartene er plassert i kategorien datamangel DD 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. This phylum contains about 10000 species; among them, most of the species are Marine and some are freshwater (about 100 species).

There may be additional data which may prove valuable to such analyses. Individual pages are individually authored and dated Svamper er den mest primitive gruppe flercellede dyr.Svamper har ingen organer og lever av å filtrere næring fra vannet gjennom et system av porer, kanaler og utstrømsåpninger. De har et støtteskjelett bestående av spikler (nåler) som er kittet sammen Svampar (Porifera) er ei rekkje dyr som lever fastsitjande i havet og tropisk ferskvatn.Dei manglar både vev som nervar og musklar og eit fast symmetrisk kroppsplan, og er såleis den mest primitive fleircella dyregruppa me kjenner til.

They can be found in shallow and in deep water Porifera, or sponges, are multicellular organisms with pores that filter water. Most sponges live in marine environments, brackish and freshwater environments. Sponges were the first creatures to branch off of the evolutionary tree, which means they are the sister to all other living creatures Demosponges (Class Demospongiae) are the most diverse class in the phylum Porifera.They include 76.2% of all species of sponges with nearly 8,800 species worldwide (World Porifera Database). They are sponges with a soft body that covers a hard, often massive skeleton made of calcium carbonate, either aragonite or calcite.They are predominantly leuconoid in structure 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.

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) View Porifera Research Papers on Academia.edu for free

Porifera, or sponges, are primitive Metazoa. They are multicellular but have no developed tissue organization, utilizing independent cellular activity to carry out all body functions. They are a successful group in ancient and recent aquatic environments with origins in pre‐Cambrian times Porifera have no permanent gonads, instead a number of areas of the sponge will, during the reproductive period, become differentiated (changed) to produce either sperm or ova (eggs). Sperm is released into the canals and is then pumped out of the sponge through the osculum, where it is likely to be drawn into the canal system of another sponge

Phylum Porifera contains more than 8,300 valid species with an estimated 4,000 awaiting discovery and/or description. Our classification and taxonomy follow that of the World Porifera Database . The ancient origin, simple body organization, close microbial associations and morphological plasticity of sponges make them one of the most challenging groups in animal systematics Porifera Pieces of sponge are able to regenerate into whole new sponges. Asexual reproduction occurs by budding or by fragmentation. The buds may remain attached to the parent or separate from it, and each bud develops into a new individual

Porifera means pore bearer in Latin, which is mainly because poriferans do have a lot of pores on their body.

Meaning of porifera. What does porifera mean? Information and translations of porifera in the most comprehensive dictionary definitions resource on the web As the name porifera means pore bearer, sponges are covered in small holes that allow water to flow into their bodies. Because the water moves into the sponge, we call them incurrent pores. Pores are also called Ostia. Osculum Water exits the sponge out of the large opening at the top called an osculum

Sponges Sponges are considered the oldest animal group. They are multicellular but don't have tissues or organs The name porifera means 'pore bearer' in Latin (a pore is a tiny hole). A sponge's body is covered by a skin, one cell thick. This skin has lots of small pores and a few large openings. The small openings are the entrances to a complex system of channels Phylum Porifera is an exclusive classification of aquatic animals.

Introduction. Sponges are an absorbing topic. If we were to define Porifera cladistically (e.g. as Porifera = Calcarea + Hexactinellida), then essentially all animals would be poriferans.That's because the Porifera, as usually conceived, are not a natural group The invertebrates, or invertebrata, are animals that do not contain bony structures, such as the cranium and vertebrae.The simplest of all the invertebrates are the Parazoans, which include only the phylum Porifera: the sponges (Figure 1). Parazoans (beside animals) do not display tissue-level organization, although they do have specialized cells that perform specific functions

Phylum Porifera includes sponges; Sponges are simple multicellular animals that lack true tissues and organs, and are asymmetrical; Larval sponges are free-swimming, adults are sessile, remaining attached to surface Porifera (Sponges) is a group of animals.There are 9049 species of sponges, in 747 genera and 143 families. This group has been around since the Ediacaran Period.Sponges includes groups like Demosponges, Calcareous Sponges , and Hexactinellid Sponges.They are feeding currents.They are sessile animals Porifera, also known as sponges, are the types of phylum that live underwater. This phylum is different from other types because the porifera has many cells that cover their exoskeleton. These cells each have different types of functions. For example, because the sponge does not have a mouth, they use their tiny pores on their body Porifera: Systematics. At one time, a diagnostic feature of the Porifera was the presence of spicules.As a result, certain fossil groups whose organization was consistent with that of living sponges were not placed within the phylum Porifera
