Water Fest Photo 5     Here is a pic of freshwater sponges collected in Wisconsin. This pic was taken at Entomologist Dean's Booth at Phalen Water Fest, Phalen Park, St. Paul, MN, May 30, 2015. We've never seen sponges; we never knew of the freshwater sponge. "Dean, Thank you very much."   Wildlife
Sponge - Wikipedia 
Sponges are animals of the phylum Porifera (/pɒˈrɪfərə/; meaning "pore bearer"). 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 circulatory systems. Instead, most rely on maintaining a constant water flow through their bodies to obtain food and oxygen and to remove wastes.
