Sponges are simple aquatic animals that belong to one of the oldest groups of living organisms on Earth, with fossil records dating back over 500 million years. Found mostly in oceans but also in some freshwater habitats, they attach themselves to rocks, coral reefs, or the sea floor. These filter-feeding creatures draw in water through tiny pores, capturing nutrients and oxygen while releasing waste. Despite lacking organs, tissues, or a nervous system, they play vital ecological roles by providing habitats for other marine species and helping maintain water quality. Many sponges also produce bioactive compounds that are valuable in medicine and scientific research. Their resilience and adaptability highlight how even the simplest forms of life contribute to the health of ecosystems. It is clear that sponges remain essential to biodiversity and marine balance.
