Sponges are animals of the phylum Porifera. They are multicellular organisms which 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 which 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, oxygen and remove wastes.
Sponge can be used to create special incandescent light bulbs and high-temperature galvanic. Rhenium, tungsten, iron alloy with high hardness,strong abrasion resistance and anti-corrosive. It has highly selective catalytic function to many chemical reactions, therefore,it is also used as a catalyst, satellite and rocket shells, atomic reactor fenders.Read More: sponge price
