Detailed explanation-1: -Clownfish use these stinging tentacles to their advantage: they acclimate themselves to an anemone by developing a layer of mucous over their bodies that makes them immune from the anemone’s stinging cells. After they gain this immunity, they are able to use the anemone as shelter, hiding from their own predators.
Detailed explanation-2: -The partnership between anemones and clownfish is known as mutualism because it provides benefits to both animals.
Detailed explanation-3: -A. clarkii achieves protection from stinging by means of its external mucus layer. This layer appears to be three to four times thicker than that of related fishes that do not inhabit anemones and consists largely of glycoprotein containing neutral polysaccharide.
