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.

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).

Sponge and Dough The sponge and dough method is a type of bulk fermentation used in bread-making. The process involves two stages. First, a light, airy sponge is created through mixing a portion of the flour, water, yeast and improving agents and allowing them to ferment. 1

Sponge Sponges have unspecialized cells that can transform into other types and that often migrate between the main cell layers and the mesohyl in the process. Sponges do not have nervous, digestive or circulatory systems. Instead, most rely on maintaining a constant water flow through their bodies to obtain food and oxygen and to remove wastes. Sponges were first to branch off the evolutionary tree from the common ancestor of all animals, making them the sister group of all other animals.

Sponge Sponges are similar to other animals in that they are multicellular, heterotrophic, lack cell walls and produce sperm cells. Unlike other animals, they lack true tissues and organs, and have no body symmetry.ponge biodiversity and morphotypes at the lip of a wall site in 60 feet of water.

- Water moves through the canals, into the chambers, and out through the central canal and osculum. THE SKELETON. The skeleton of a sea sponge is made up of tiny needlelike splinters called spicules. Spicules consist of a mesh of protein called spongin.Many sea sponges can only be identified by the microscopic examination of the skeleton.Because of this, indentification from photographs can become very difficult. sea sponge's body primarily consists of spicules and spongin. Spicules are needle shaped fiberlike structures that act as the sponge's skeleton. Spongin is a protein that helps provide body support. In some instances the spongin will combine with the spicules to provied support, in other times the spongin works alone.

- Sponges are the simplest form of an animal. They are what scientists call an evolutionary dead-end. This means that they didn't evolve into anything. 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. Sponges eat by filter feeding.

What Are Sea Sponges? Sea sponges – as found in their natural un-harvested state – are comprised of a hard, shell-like protective outer layer covered with tiny pore-like holes which travel deep down into and all throughout the soft structure within.

Sponge Sponges, the members of the phylum Porifera, are a basal Metazoa clade as sister of the Diploblasts. 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. Sponges have unspecialized cells that can transform into other types and that often migrate between the main cell layers and the mesohyl in the process. Sponges do not have nervous, digestive or circula

- Quick Answer. Sea sponges are animals that live on the ocean floor. After human beings harvest and dry them, the sponges serve as the household tool many people use to bathe and wash dishes and cars, among other items.

- Sponges (Porifera) are a group of animals that includes about 10,000 living species.Members of this group include glass sponges, demosponges, and calcareous sponges. Adult sponges are sessile animals that live attached to hard rocky surfaces, shells, or submerged objects. The larvae are ciliated, free-swimming creatures.ponges are classified within the following taxonomic hierarchy: Animals Invertebrates. Sponges are divided into the following taxonomic groups: 1  Calcarious sponges (Calcarea) - There area about 400 species of calcarious sponges alive today.

- Porifera (Sponges) Sponges (Phylum Porifera) are a group of simple aquatic invertebrates that include three groups - Glass sponges, Demosponges and Calcareous sponges. There are about 5,000 to 10,000 species of sponges found mostly in marine environments with about 100 species of freshwater sponges.

Sponge This article is about the aquatic animal. For the porous cleaning tool, see Sponge (material). For other uses, see Sponge (disambiguation). Sponges are the basalmost clade of animals of the phylum Porifera (/pɒˈrɪfərə/; meaning pore bearer). They are multicellular parazoan 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.

The Life of a Sponge The Life of a Sponge. Elephant ear sponge, © 2006 Richard Ling. The word sponge, for most of us relates to the scrubbing sponge or a bath sponge. It is easy to forget that there is much more to sponges than the scrubbing and bath. The sponges are living animals that live in the water.orifera means pore-bearing. Sponges are covered with tiny pores on the outside called ostia (2). Ostia lead to an internal system of canals which leads to one or more larger holes called oscula, which are the openings to the out side.

The Life of a Sponge Most are sponges are asymmetrical, though some of them exhibit radial symmetry (Dawkins 2004). The typical body form of a sponge consists of a hollow pitcher surrounded by lots of small holes and opens up on the top with a big hole.Sponges do not have a coelom.orifera means pore-bearing. Sponges are covered with tiny pores on the outside called ostia (2). Ostia lead to an internal system of canals which leads to one or more larger holes called oscula, which are the openings to the out side.

- Sponges collect bacteria when they filter the water around them. These bacteria are believed to be able to do many things. First, these bacteria may be able to create forms of nitrogen from the nitrogen gas in the water that may be nutritional for the sponge.hey don’t have muscles, a nervous system, or a circulatory system. Their walls are lined with many small pores called ostia that allow water flow into the sponge. The structure of a sponge is simple. One end is attached to a solid such as a rock while the other end, called the osculum, is open to the environment.

- Sponge Fossils Sponge, belonging to the phylum Porifera, is a multicellular creature in the simplest form. The meaning of the word Porifera is 'pore bearer' and it is named so because of the channels and pores present in the Sponge body. Thus, water is circulated throughout the body to help with feeding and breathing.

SpongeBob SquarePants The series revolves around its title character and his various friends. SpongeBob SquarePants is an energetic and optimistic sea sponge (although his appearance more closely resembles a kitchen sponge) who lives in a sea pineapple and loves his job as a fry cook at the Krusty Krab. He has a pet snail, Gary, who meows like a cat.

- Sponges do have several distinct types of cells, each with different functions. (See FIG.) The body wall of a sponge is perforated by numerous pores or ostia through which water is drawn into a central cavity called the spongocoel or central cavity. The osculum is a large opening at one end of the sponge through which all the resulting excurrent is evacuated.
