Clownfish live among sea anemones, which provide them with protection from predators. The clownfish are also known to clean the sea anemones of parasites. This relationship is beneficial to both species.
2. Coral and algae
Coral reefs are formed by the interaction between coral and algae. The coral provides a home for the algae, while the algae provide the coral with food through photosynthesis. This relationship is essential for the survival of both coral and algae.
3. Cleaner fish and larger fish
Cleaner fish remove parasites and dead skin from larger fish. This relationship is beneficial to both species, as the larger fish are kept free of parasites and the cleaner fish receive food.
