The colorful clown anemonefish, also called a clownfish, is bright orange with three white stripes—and probably reminds you of the star of the popular movie Finding Nemo. This four-inch-long (10-centimeter-long) fish shares an amazing partnership with another sea creature: the anemone (pronounced: uh-NEM-uh-NEE). The partnership benefits both participants, and the close relationship led to the fish being named an anemonefish.
Anemones have tentacles that sting, but the clownfish isn't bothered by them. In fact, it lives among the tentacles. How can this fish do that and survive? Because it has a layer of mucus on its skin that makes it immune to the anemone's stings.
