Freshwater Sponges are a category of aquatic invertebrates in the Poriferans species, belonging to the broader group of animals. They are specialized organisms that thrive in freshwater environments, unlike the majority of sponge species that inhabit saltwater ecosystems. Despite being under the same animal kingdom as amphibians, they have unique characteristics and biological structures. Their primary role in the ecosystem is to filter water, thereby contributing to its purification.
