odies consist of a foot attached to the substrate, an oral disc surrounded by stinging tentacles and a central mouth that also serves as an anus. Sea anemones and clownfish maintain a mutually beneficial symbiotic relationship. Anemones and clownfish are inseparable. Anemones are hosts not only to clownfish but also to damselfish, crabs and commensal shrimps. They are also home to unicellular algae known as zooxanthellae, which are responsible for the bright colours of anemones through photosynthesis. Clownfish hunt predators that eat anemone tentacles. They also rid the anemones of parasites and feed their host. They oxygenate the host by constantly moving and rubbing against it.
