Sponges are primitive, sessile, mostly marine, waterdwelling filter feeders that pump water through their matrix to filter out particulates of food matter. Sponges are among the simplest of animals, with partially differentiated tissues but without muscles, nerves, or internal organs.he structure of a sponge is simple: it is shaped like a tube, with one end stuck to a rock or other object and an open end, the osculum, open to the environment. The spongocoel, or interior of the sponge, is composed of walls perforated with microscopic pores that allow water to flow through the spongocoel.
It is believed that, there are around 5000 to 10,000 species of sponges, and most of them are found in sea water. So, sponges are unique aquatic animals with some interesting characteristics. Sponges are primarily found as a part of the marine biome; but, around 100 to 150 species can be found in freshwater.They may resemble plants, but are actually animals that are sessile (not capable of movements). So, sponges are made of these specialized cells, and they do not have any head, trunk, bodily organs, or appendages. 2  They are simple multicellular organisms. 3  Sponges are filter feeders, who absorb nutrients as well as oxygen from the water, that enters its body through the pores.
