    Morphology of Sponges. There are at least 5, named species of sponges, likely with thousands more yet to be classified. The morphology of the simplest sponges takes the shape of an irregular cylinder with a large central cavity, the spongocoel, occupying the inside of the cylinder ().Water enters into the spongocoel through numerous pores, or ostia, that create openings in the body wall.

The Porifera are sponges. They are primarily marine animals. There are nine thousand species of sponges. There are following characteristics of the phylum Porifera: Their bodies consist of loosely organized cells. They vary in size from less than a centimeter to a mass that can fill your arm.

They are asymmetrical or radially symmetrical. Morphology of Sponges. There are at least 5, named species of sponges, likely with thousands more yet to be classified. The morphology of the simplest sponges takes the shape of an irregular cylinder with a large central cavity, the spongocoel, occupying the inside of the cylinder (Figure ).Water enters into the spongocoel through numerous pores, or ostia, that create openings in the.

Asexual methods of reproduction include: the growth of stolons that develop into new individuals; a bud separating from the parent sponge and creating a new sponge elsewhere; and the simple act of parts of a sponge breaking of and establishing in a new location.

40 Phylum Porifera. Organisms. Porifera. Sponges are unique creatures. They are in the Phylum Porifera and there are about 5, different known species. They are one of the simplest forms of multi-cellular animals and come in a variety of different colors, shapes, and sizes.

The phylum Porifera includes a number of simple animals commonly referred to as sponges. Sponges filter and consume fine food particles through their pores.

Most sponges live attached to rocks, plants, or other animals in marine environments. Phylum Cnidaria includes animals that show radial or biradial symmetry and are diploblastic, The Biology of the porifera book is, they develop from two embryonic layers.

Nearly all (about 99 percent) cnidarians are marine species. Cnidarians contain specialized cells known as cnidocytes (“stinging cells”) containing organelles called nematocysts (stingers). These cells are present around the mouth and tentacles, and.

The invertebrates, or invertebrata, are animals that do not contain bony structures, such as the cranium and simplest of all the invertebrates are the Parazoans, which include only the phylum Porifera: the sponges ().Parazoans (“beside animals”) do not display tissue-level organization, although they do have specialized cells that perform specific functions.

In biology, a phylum (/ ˈ f aɪ l əm /; plural: phyla) is a level of classification or taxonomic rank below kingdom and above ionally, in botany the term division has been used instead of phylum, although the International Code of Nomenclature for algae, fungi, and plants accepts the terms as equivalent.

Depending on definitions, the animal kingdom Animalia or Metazoa contains. Genre/Form: Congress Congresses Conference papers and proceedings: Additional Physical Format: Online version: Biology of the porifera.

[London] Published for the Zoological Society of London by Academic Press, the phylum Porifera dwell only in the ocean. Yet sponges are common and sometimes abundant in­ habitants of a broad diversity of freshwater commu­ nities. In some habitats they comprise a major com­ ponent of the benthic fauna and may play important roles in ecosystem processes.

Sponges are the simplest of the multicellular phyla. The invertebrates, or invertebrata, are animals that do not contain bony structures, such as the cranium and 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.

A Guide for the Study of Animals. This guide to the study of animals is intended for pupils in secondary schools. Topics covered includes: Introductory Studies of Living Animals, Studies of Insects, The Connection between Structure and Function, Adaptation to Surroundings, Adaptation for Protection from Enemies, Vertebrates, Adaptations for the Preservation of the Species, Poultry.

Sponges (phylum Porifera) are known to be very rich sources for bioactive compounds, mainly secondary metabolites. Main efforts are devoted to cell- and mariculture of sponges to assure a sustainable exploitation of bioactive compounds from biological starting : Paperback.

Sponges lack true tissues, have no body symmetry, and are sessile; types are classified based on presence and composition of spicules. As larvae, sponges are able to swim, but as adults, they are sessile, spending their life attached to a substrate. Although the majority of sponges live in marine habitats, one family, the Spongillidae, is found.

Main efforts are devoted to cell- and mariculture of sponges to assure a sustainable exploitation of bioactive compounds from biological starting material. These activities are flanked by improved technologies to cultivate bacteria and fungi which are associated with the sponges.

Porifera - Biology Encyclopedia; Porifera Porifera, or sponges, are the simplest and oldest of the multicelled animals, with fossils dating back to Precambrian times.

They are aquatic and sessile, living permanently attached to submerged objects. More than 5, species are known, most of which occur in shallow coastal waters and in the deep sea. The simplest of all the invertebrates are the Parazoans, which include only the phylum Porifera.

Phylum Porifera (“pori” = pores, “fera” = bearers) are popularly known as sponges. Sponge larvae are able to swim; however, adults are non-motile and spend their life attached to a substratum through a holdfast. Aspects of Sponge Biology is the result of a symposium about sponge biology held in Albany, New York in May The symposium not only presents investigations, but also problem areas in the field of sponge biology.

This book therefore shows that sponges are a very challenging and untouched subject area for future studies.
