- Sponges are a group of invertebrates that includes glass sponges, demisponges, and calcareous sponges. There are about 10,000 species of sponges alive today. The earliest fossil evidence of sponges consists of various cells known to belong to sponges—spicules, pinacocytes, porocytes and archaeocytes.lthough there more than 30 phyla of invertebrates, and scientists are constantly reshuffling the way they classify them, in this article I'll keep it simple by focusing on just six basic groups of invertebrates.

Polyp and medusa body shapes Corals, sea anemones and jellyfish belong to a group of animals called cnidarians. They have a simple body consisting of a central gut cavity surrounded by tentacles. A jelly-like substance called mesoglea lies between the outer and inner layers of the body. There are two basic cnidarian body ...

- Your scratch may be in the coating rather than in the brass itself. Clean your piece of brass well and buff it thoroughly. Then, take a bit of lacquer thinner or acetone on a soft cotton cloth and rub the scratch to remove the coating. If the scratch disappears, buff energetically and restore the protective coating.f the scratch doesn't soften, you may need to use some more abrasive tools. Use abrasion wisely. If you think you need to use abrasives, make absolutely sure that you are working with solid, not plated brass. A magnet will stick to solid brass. Take plated brass to the jeweler or refinisher.

- Description [edit]. Parazoans differ from their choanoflagellate ancestors in that they are not microscopic and have differentiated cells. However, they are an outgroup of the animal phylogenetic tree being that they do not have tissues or organs.The only surviving parazoans are the sponges, which belong to the phylum Porifera, and the Trichoplax in the phylum Placozoa.arazoans differ from their choanoflagellate ancestors in that they are not microscopic and have differentiated cells.

Phylum Porifera: Definition, Characteristics & Examples Why, you ask? Well, the term Porifera is actually the scientific name given to the group of organisms known commonly as sponges. But, unlike SpongeBob, living sponges are neither square in shape nor in interest- they are actually a really important and diverse phylum within the animal kingdom.

Crustaceans, Subphylum Crustacea Crustaceans belong to the phylum Arthropoda, along with insects, arachnids, millipedes, centipedes, and fossil trilobites. However, crustaceans occupy their own subphylum, Crustacea.The term crustacean derives from the Latin crusta, meaning crust or hard shell. small number of crustaceans live on land. Whether marine or terrestrial, crustaceans share certain traits that determine their inclusion in the subphylum Crustacea. As with any large group of organisms, exceptions to these rules will occasionally apply.

What they mostly have in common is that they don't swim, at least not much. Nearly every category of animal is included in the benthos.

- Grantia Sponge. Sponges, colonial animals in the phylum Porifera, are primitive invertebrates that are dominated by marine species. Typically, they are benthic, sessile filter feeders that are asymmetrical. Grantia is a genus of calcareous marine sponges that is sometimes referred to as Scypha in older texts.

Sponge A comparison in 2007 of nuclear DNA, excluding glass sponges and comb jellies, concluded that: Homoscleromorpha are most closely related to Eumetazoa; calcareous sponges are the next closest; the other demosponges are evolutionary aunts of these groups; and the chancelloriids, bag-like animals whose fossils are found in Cambrian rocks, may be sponges.

28.1: Phylum Porifera Explain the various body forms and bodily functions of sponges 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 28.1.1).

Characteristics of Sponges: BTW, They are Animals, NOT Plants! It is believed that, there are around 5000 to 10,000 species of sponges, and most of them are found in sea water. So, sponges are unique aquatic animals with some interesting characteristics. Sponges are primarily found as a part of the marine biome; but, around 100 to 150 species can be found in freshwater.They may resemble plants, but are actually animals that are sessile (not capable of movements). So, sponges are made of these specialized cells, and they do not have any head, trunk, bodily organs, or appendages. 2  They are simple multicellular organisms. 3  Sponges are filter feeders, who absorb nutrients as well as oxygen from the water, that enters its body through the pores.

- sponges are classified in the phylum porifera a word that comes from the latin words porus pore and ferre bear meaning pore bearer this is a reference to the numerous holes pores on the sponge s surfaceponges do not have tissues or organs like some animals do but they have specialized cells to perform necessary functions these cells each have a job some are in charge of digestion some reproduction some bringing in water so the sponge can filter feed and some for getting rid of wastes

- A sponge is a member of the phylum Porifera. It is a simple animal with many cells, but no mouth, muscles, heart or brain. It is sessile: it cannot move from place to place the way most other animals can. A sponge is an animal that grows in one spot like most plants do.

General Biology/Print version Sponges (poriferans) are very simple animals that live permanently attached to a location in the water - they are sessile as adults. There are from 5,000 to 10,000 known species of sponges. Most sponges live in salt water - only about 150 species live in fresh water. Sponges evolved over 500 million years ago. The body of this primitive animal has thousands of pores which let water flow through it continually.

Sponge Sponges are animals of the phylum Porifera (/pɒˈrɪfərə/ ; meaning pore bearer). 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.he networks of water passages in glass sponges are similar to the leuconid structure. In all three types of structure the cross-section area of the choanocyte-lined regions is much greater than that of the intake and outlet channels.

- Class Demospongia. Class Demospongia is by far the most diverse class of sponges, with over 95% of the known species. Most Demospongia have siliceous spicules, although none of these are the 6-pointed type found in hexactinellids.A number of species in class Demospongia have a skeleton made of interlocking, flexible fibers of collagen.n high wave-shock areas, these sponges are usually only a centimeter or two in thickness. Another good place for biology classes to find living sponges is attached to submerged wood in lakes or streams. Sponges are the simplest living animals, but they are often brightly-colored and spectacular.
