- Poriferans don't have mouths; instead, they have tiny pores (ostia) in their outer walls through which water is drawn (figure 2). Water enters through the ostia, flows through canals to a spacious chamber called a spongocoel, and finally exits through large openings called oscula.

- Definition of PORIFERA. : a phylum of primitive invertebrate animals comprising the sponges and having a cellular grade of construction without true tissue or organ formation but with the body permeated by canals and chambers through which a current of water flows and passes in its course through one or more cavities lined with choanocytes.ew Latin, from Latin porus pore + -i- + -fera, neuter plural of-fer-ferous.

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.

Porifera Characteristics Characteristics of Phylum Porifera. Sponges have a variety of shapes. Some form crusts, some are simple tubes, some are vase shape while others can be cup shaped, massive clumps, fan shaped, finger like bulges, treelike or even bushy. They maybe soft, brittle or hard.he volume of water passing through a sponge daily is as much as 20000 times the volume of the sponge itself! Being ubiquitous in nature, they occur in rivers to rock pools to deep oceans and even in the frozen and tropical seas. Some of the important characteristics of Phylum Porifera are as given below.

Porifera sponges Other 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).

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.

Porifera (pōrĭf`ərə) [Lat.,=pore bearer], animal phylum consisting of the organisms commonly called sponges sponge,common name for members of the aquatic animal phylum Porifera, and for the dried, processed skeletons of certain species used to hold water.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.

- Porifera. - 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.ponges that reproduce asexually produce buds or, more often, gemmules, which are packets of several cells of various types inside a protective covering. Fresh water sponges of the Spongillidae often produce gemmules prior to winter. These then develop into adult sponges beginning the following spring.

- Of the many phyla of multicellular animals, one is most often separated by biologists out into its own Kingdom: the sponges group, Porifera. There are reasons to think that the protozoa that led to their multicelled existence were different than those that led to the rest of the animals, and that alone should put them in a different Kingdom.

Major Phyla Of Animals Animal phyla are classified according to certain criteria, including the type of coelom, symmetry, body plan, and presence of segmentation. Sponges (Porifera) have a primitive cellular level of organization and lack tissues and symmetry. They depend on a flow of water through the body to acquire food.

What Are Sea Sponges? Identifying a Sea Sponge. The natural sea sponge is one of the world’s simplest multi-cellular living organisms. The sponge’s scientific classification is “Porifera,” which literally means “pore-bearing,” and refers to the countless tiny openings or holes visible on all sponges. Sponges grow in all different shapes, sizes, colors, and textures.

Phylum Porifera Circulatory System: Porifera do not have a circulatory system. Type of Symmetry: Porifera are most commonly asymmetrical but can also have radial symmetry. Type of Coelom: Porifera have no coelom. Type of Body Plan: Porifera use canals and pores (diffusion) to perform life functions. Number of body layers: Porifera have no real body layers but they do have 2 cell layers; an outer layer that makes up the epidermis, and an inner layer that makes the inner cavities. Specialized Cells: Porifera have
