Clownfish and Sea Anemones - A Working Relationship
![]() |
The clownfish not only gets a wonderful living defense system from the anemone, but also an occasional meal from the scraps of fish the anemone fails to ingest. This relationship works both ways as the anemone will snack on any scraps the clownfish drops as well. The action of the clownfish also stirs up fresh water currents and moves them over the sedentary anemone.
So, how does the anemone know not to sting? There are a few different theories. One is that the anemone doesn't know, but that the mucus coating of the clownfish protects it from the anemone's toxins. This is possible because clownfish that have had this mucus wiped off of them have been stung and killed by their previous hosts. Another theory states that the chemical content of the mucus coating prevents the anemone from recognizing the clownfish as a food source, and therefore the anemone fails to react to the little fish's presence.

Dancing with the Clownfish

You may recognize the clown anemonefish or clownfish because of its bright orange color and three white stripes. Or you might recognize it from the movie Finding Nemo. This clownfish is named after the sea anemones in which it inhabits. A layer of mucus surrounding the fish’s skin protects them from the anemones’ poisonous sting. To become comfortable amongst the anemones, the clownfish performs a ritualistic dance with an anemone before deciding to live there. In exchange for protection and food scraps, the clownfish scares off intruders and removes unwanted parasites.
Bonus Fact: All clownfish are born male. They can change sexes; however, they only do when they want to become the dominant female of the group because the change is irreversible.
