Anemomefish
Anemonefish are a unique group of fish that live amongst the tentacles of sea anemones. The anemone's tentacles sting and paralyze most fish that brush against them. Fortunately, anemonefishes have a layer of mucus covering their skin that prevents the anemones from stinging them. By seeking shelter amongst the sea anemone's tentacles, the anemone fish are protected from other predatorial fish that might otherwise see the anemonefish as a meal.
Anemonefish are never found far from the protection of their host anemone. Scientists belive the anemonefish provide benefits to the anemones as well. The anemonefish drops scraps of food as it eats and the anemone cleans up the left overs. Anemonefishes are also territorial and drive off butterflyfishes and other anemone-eating fishes.
