Porifera
English: Sponges.
Name: Porifera means "pore bearer".

Zoology
Porifera are multicellular organisms with bodies full of pores and channels allowing water to circulate through them. The bodies consist of jelly-like mesohyl sandwiched between two thin layers of cells.
Their cells are unspecialized, can transform into other types, can migrate between the main cell layers and the mesohyl.
Sponges do not have nervous, digestive or circulatory systems. A constant water flow through their bodies provides for food and oxygen and removes wastes.
