The other water quality parameters were not found to correlate with any fish community or species metrics. Each of these cells has a job: some are in charge of digestion, others reproduce, others carry water and the sponge can filter the food, and others are used to get rid of the waste. Some sponges (e.g., the Spongillidae) are often greenish because green algae live in a symbiotic relationship within them; others are violet or pinkish, because they harbour symbiotic blue-green algae.
