Anemonefishes or clownfishes live within a host anemone in a symbiotic relationship. Anemones are related to coral and have stinging cells calls nemotacysts which are used to sting and capture small animals for food. Anemonefishes develop a special mucous on their skin that prevents them from being stung by the host anemone and therefore find protection from predators by hiding within the anemone.
