Symbiosis I SL130796
Anemonefish - in this instance the pink anemonefish - and sea anemones have a symbiotic, mutualistic relationship, each providing many benefits to the other. The sea anemone protects the anemonefish from predators, as well as providing food through the scraps left from the anemone's meals and occasional dead anemone tentacles, and functions as a safe nest site. In return, the anemonefish defends the anemone from its predators and parasites. The anemone also picks up nutrients from the anemonefish's excrement. This behaviour is known as symbiosis. This is the pink anemonefish, one of several species found on the Great Barrier Reef.
