Sponges are natural filters. They grow near and around coral reefs and help clean the ocean of plankton and algae. For hundreds of years, they have been prized for their natural absorbency and are harvested even today to be used as high-end bathing tools. Modern synthetic sponges mimic the structure of natural sponges simply because that structure makes them effective cleaning tools.
