Why aren clownfish stung by anemones?
Indo- Pacific reef anemones are known for their symbiotic (both benefit) relationship with clownfish. An anemone’s stinging tentacles provide refuge for these fishes and their eggs. Scientists believe that the clownfish may be coated with a mucous that protects it from the anemones venom. In return, clownfish may protect the anemone from predators such as butterflyfish. Clownfish may even remove parasites and algae from their host anemones.
