What is economic importance of spongilla?
Ans: Spongilla is a type of freshwater sponges in the family of Spongillidae which are usually found in lakes and slow streams. These usually attach on to the rocks and help in filtering the water. These sponges serve as houses for animals like small fishes, molluscs and crustaceans. The penetrable surface of the sponges allows rich supply of water and food such as algae and bacteria into the sponge. Eventually, the animals living inside the sponge also get the food supply from the water circulating.
