Canal system of the body helps in circulating water throughout the body to bring in food and oxygen. Within each of the two subclasses of hexactinellids are sponges with loose skeletons—spicules held together by living tissue—and sponges with fused skeletons. They usually inhabit shallow waters, although there is evidence that they can inhabit abyssal areas at depths of even 6000 meters. 2. The phylum Cnidaria includes animals that show radial or biradial symmetry and are diploblastic. The species belonging to this class are small and rarely exceed 10 centimeters. Protozoans, Sponges, Coelenterates and many worms have a direct diffusion of gases. Therefore, the natural cellulose sponge is able to absorb 20 times its own dry weight of water and retain this in its pore structure. Sponges lack organs and specialized tissue; flagellated cells move water into the central cavity through the perforations, and individual cells digest food (bacteria, other microorganisms, and organic debris), excrete waste, and absorb oxygen.

Some deep sea sponges have evolved carnivorous feeding strategies and trap small crustaceans using hook shaped structures. The simplest of all the invertebrates are the Parazoans, which include only the phylum Porifera: the . Grant discovered that sponges eat tiny particles of organic matter in the circulating water, further establishing the sponges' animal characteristics. It is through this way that sea sponges multiply among the marine sponge's community. All sponges are aquatic, most are marine, found from the deepest oceans to sub-terrestrial environments (where they can survive remarkably well). Such a brief description though does not do them justice. Their bodies are radially symmetrical or asymmetrical. The most common colors are brown, reddish-brown, grey, and purple. In some areas, the sponge can account for about 9% of the total reef substrate. Rarely are they found completely free-floating. Water entering the spongocoel is expelled via a large common . Currents push water through open pores and internal channels that allow for respiration, feeding, and waste removal.

It is use to maintain the most in agriculture like in radish and some fast-growing seeds. Stromatoporoidea -- 3. Description of the Sea Sponge. Cnidarians possess a well-formed digestive system and carry out extracellular digestion. • Planktonic larvae or mini flagellated colonies are released to colonize new areas. Most of them are marine while a few are fresh water forms. Approximately 10,000 species of sponges are known at present, and the phylum is divided into three classes, viz., Calcarea or Calcispongiae, Hexactinellida or Hyalospongiae, and Demospongiae and about twelve orders chiefly on the type of skeleton. It is possible for one single sponge cell to survive, reproduce and create a whole new sponge colony. The most common examples of protostome sub-phyla are mollusks, arthropods, and annelids. They have a porous structure which is similar to the normal sponge we use. Sponges are one of the most primitive animals living on the planet. Sponges Phylum Porifera Chapter 6 Zoology Phylum Porifera; Hexactinellida ← -- 5. An example of the morphological differences between sponges can be seen below in Figures 3 and 4. The body is cylindrical in structure and exhibits radial symmetry. The color of sponges ranges from white and beige, to shades of green, brown, yellow, red, purple, lavender, and blue.
