A sea anemone has tentacles (similar to jellyfish) that deliver a chemical sting to animals that come in direct contact with them. Clownfish, however, are immune to the sea anemone's sting. They live among the tentacles of sea anemones and rely on the anemones for protection.

Sea anemones are filter feeders, and the movement of the clownfish increases the current of water flowing through the anemone. In addition, clownfish tend to drop scraps of food as they feed. What type of relationship exists between the clownfish and the sea anemone?
A. parasitism
B. predation
C. mutualism
D. commensalism
