The sponges in the ocean are completely different than the kitchen cleaning sponges we know. Sponges are important in nutrient cycles in the coral reef cycles, their process lowers excess nitrogen levels in coral reefs, also preventing harmful ecosystem changes.

Scientists believe that the conversion of nitrogen gas into useful nitrogen is also beneficial to the survival of other organisms in the coral reef area. They are hoping to have discovered a pathway for the removal of excess nitrogen from coral reefs ( According to Ed Yong in The New Yorker, he says that there are around eighty five hundred known species of sponges living in both freshwater and oceans. He also states that off the coast of Canada reefs of glass sponges can clean up to 500 vertical feet of overlying water. The University of Rhode Island has an article as to why sponges are important, they state that sponges are the most prolific source of marine natural products with human health applications.

Sponges are among the most simplest of animals because they are the only multicellular animals without a nervous system and they do not have any nerve cells or sensory cells. Us humans have increased the carbon dioxide in the air, and as a result we are acidifying the ocean from pollution.
