Barrier Reef, Australia

 The sea anemone has a foot which normally attaches itself to rocks or the sand. Some species attach themselves to kelp and others are free-swimming. Although they are not plants and therefore are incapable of photosynthesis themselves, many sea anemones form an important symbiosis with certain single-celled green algae species which live in the animals’ gastrodermal cells.
