Cnidarians, which include jellyfish, corals, and sea anemones, play a significant role in marine ecosystems. They contribute to biodiversity, provide habitat for various marine species, and are essential in nutrient cycling. Additionally, their presence can indicate the health of marine environments, making them important indicators for ecological studies. Overall, cnidarians are vital for maintaining the balance and function of oceanic ecosystems.
