Most sponges are known to live in salt water, and only one family of them grows in freshwater, which is called the genus Spongilla.

There are six out of them reside in the lakes, rivers, and ponds of Illinois, as well as slow-flowing or standing water. Although Spongilla can reach a width of one meter, its height rarely gets more than 15 centimeters.
Based on scientific estimation, approximately 75 species can survive in a new habitat that is different from their original life.
As mentioned before, people can find freshwater sponges in lakes, rivers, streams, and ponds. They grow on the surface of submerged solids. Thanks to being sensitive to the living environment, these species can indicate excellent water quality and negligible pollution levels.
Sponges are categorized as filter feeders. It means particles and tiny organisms existing in the tank are their food, filtered by circulating water through their body structure. Besides, these creatures also get nutrients from the sticking symbiotic algae.

Freshwater sponges are motionless organisms residing at water bodies’ bottoms. Despite having no backbone and organs, these species possess specialized cells to filter the food in water flows. They crave bacterioplankton, organic particles, and the nutrients the symbiotic algae produce.
Amateurs may mistake the green algae for the freshwater sponges. However, they are different in texture and thickness. Sponges’ texture is coarse and thicker compared to the algae living on them.
Once minor pieces are broken, these organisms can reproduce either asexually or sexually as a replacement. The same goes for the broken parts after forming gemmules, which are overwintered reproductive spheres creating newborns.
Scientists analyze the structure of gemmules through a microscope to categorize the species levels.

Freshwater sponges take responsibility for filtering the particles from their aquarium environment. The water flows through their cell walls, which draws dissolved organic elements.
This process produces a nutritious solution and converts the bacteria into energy to absorb. This energy helps them develop and survive in a low-nutrient environment.
