Friends and Anemones

A clownfish hides within a sea anemone in the waters off Indonesia. Clownfish always make their homes in anemones, and the species share a mutually beneficial, or symbiotic, relationship. The anemone's stinging tentacles ward off fish that predate on clownfish. In return, the clownfish clean the anemone, and its waste provides nutrients for the anemone.
