Clownfish are known to reside amongst the tentacles of sea anemones, which are fascinating and creatures of the sea. This unique relationship between clownfish and anemone is defined as symbiosis or a symbiotic relationship. The clown anemonefish is therefore referred to as the host of sea anemones.  The clownfish treats the sea anemone's thick tentacles as a home which in turn also serves as a protective barrier from predators. In return, the clownfish helps in removing parasites that plague the sea anemone by feeding on them and thereby help it thrive. The clownfish, therefore, is at a higher advantage. There are known to be over 100 distinguished varieties of sea anemones but only a select few are clownfish anemones.  Anemones are said to be poisonous to many sea creatures which helps keep predators of the clownfish at bay, but the clownfish has immunity over the poison because it has a layer of mucus on their skin.
