Sponge 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.Nevertheless, sponges are quite successful. sponge is a member of the phylum Porifera.

- Phylum Porifera. The phylum Porifera is a phylum consisting of multicellular organisms which have bodies full of pores and channels allowing water to circulate through them. Organisms from this phylum are tube sponges, yellow sponges, and spongilla. Their bodies consist of a tissue called mesohyl.They have no definite symmetry.he phylum Porifera is a phylum consisting of multicellular organisms which have bodies full of pores and channels allowing water to circulate through them.

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.ll freshwater and most shallow-water marine sponges have leuconid bodies. The 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.

Marine Sponge: Sponge-Bacteria Association Overview of Marine Sponges. Marine sponges are natural bath sponges (with living cells removed) that we all are familiar with. They actually are the oldest and simplest animals that have been living on earth for millions of years. There are various types of sponges under Phylum PORIFERA.

- Introduction to Primitive Invertebrates. Today well examine several phyla that represent alternate pathways in early animal evolution. The sponges, in the Phylum Porifera, are so strange that they are placed in the Subkingdom Parazoa, which literally means “animals set aside”.All other animals belong to the Subkingdom Eumetazoa (“true” animals).oday well examine several phyla that represent alternate pathways in early animal evolution.

- 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. [Calcarea, L. Calcarious = limy, Calcispongiae, L. Calcis = genitive of calx = lime or chalk]

Marine Biology Sponges are the simplest form of multi-cellular animals. They are very diverse and come in a large variety of colours, shapes and structural complexities. They range in heights of 1-200cm and in diameters of 1-150cm. They have partially differentiated tissues, and not true tissues.

- 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.

- Recall from above that Aurelia aurita is a scyphozoan belonging to the phylum Cnidaria. The phylum Cnidaria is very closely related to the phylum Ctenophora which consists of comb jellies. Both of these organisms are placed seperately from the phylum Porifera (sponges) becasue the are eumetazoans.enus Aurelia basically consists of a variety of moon jellyfish, most well-known, of course, is the species Aurelia aurita. The reasons for the classification of Aurelia aurita is very understandable when the characteristics of each group, stated above, are taken into consideration.

The Life of a Sponge The skeleton of the sponge is composed of tiny needle-like splinters called spicules, a mesh of protein called spongin, or a combination of both. Many sponges can only be identified by microscopic examination of the skeleton, which makes certain identification from photographs difficult.he collar cells have a sticky, funnel shaped collar and a hairlike whip, called a flagellum. The collar cells serve two purposes. First, they beat their flagella back and forth to force water through the sponge. The water brings in nutrients and oxygen, while it carries out waste and carbon dioxide.

Porifera sponges Sponges are a diverse group of sometimes common types, with about 5000 species known across the world. Sponges are primarily marine, but around 150 species live in fresh water.ther characteristics of sponges include a system of pores (also called ostia) and canals, through which water passes. Water movement is driven by the beating of flagellae, which are located on specialized cells called choanocytes (collar cells).

Sponges reproduce using … this method called budding. They catch sperm and the baby grows inside the sponge and then the baby is released and it swims around.hey are what scientists call an evolutionary dead-end.

- There are too many classes to go into here, but I can go into phyla, one level up from classes. We have: - Porifera (sponges) - Cnidaria (jellyfish) - Mollusca (molluscs … ) - Platyhelminthes (flatworms) - Nematoda (roundworms) - Annelida (ringworms) - Echinodermata (starfish, sea urchins and cucumbers) - Vertebrata (vertebrates) and quite a few others, but these are the most distinct.

- Most (but not all) sponges are asymmetrical and have no definite shape. Sponges, like all animals, are eukaryotic-meaning their cells have a nucleus. Porifera in Latin means pore-bearer and refers to the many pores or openings in these animals.Because of these pores, a sponge can soak up and release water. At one time, real sponges were used for cleaning and bathing.ost (but not all) sponges are asymmetrical and have no definite shape.

Porifera Sponges (phylum Porifera) are an exclusively aquatic and, with a few exceptions (Vacelet and Boury-Esnault 1995), a filter-feeding group of animals. The group consists of approximately 15,000 extant species in three distinct groups (Hooper and van Soest 2002):econd, the syncytial tissue in glass sponges appears to be a derived trait within this group because the development of glass sponges starts with a cellular embryo (Leys, Cheung, and Boury-Esnault 2006).

Sponge Written By: 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.

Porifera Porifera. (invertebrate zoology). The sponges, a phylum of the animal kingdom characterized by the presence of canal systems and chambers through which water is drawn in and released; tissues and organs are absent.he beating of flagella on collar cells or choanocytes, localized in chambers on the interior of the sponge, maintains the water current. Support for the sponge tissues is provided by calcareous or siliceous spicules, or by organic fibers, or by a combination of organic fibers and siliceous spicules.

They range in heights of 1-200cm and in diameters of 1-150cm.They have partially differentiated tissues, and not true tissues.Sponges don’t have internal organs.he first are the collar cells, which line the canals in the interior of the sponge. Flagella are attached to the ends of the cells and they help pump water through the sponge’s body. By pumping water, they help bring oxygen and nutrients to the sponge while also removing waste and carbon dioxide.

- Sponges. Above: a Pov-Ray model of a sponge. Sponges belong to the phylum Porifera, which literally many 'many pores' since the surface of a sponge is covered in minute pores that suck in water and nutrients, which the sponge filters before expelling the water from a large opening or osculum.
