The tube anemone, or tube dwelling anemone, lives in a mucous tube on the muddy bottoms of coastal waters, estuaries and soft seabeds. These attractive anemones are found in tropical and subtropical waters throughout the world, where they can grow up to 15 cm (6in) across and 30 cm (12in) tall. When it is threatened, the animal retracts into its tube for protection. The beautiful stinging tentacles vary from a vibrant purple to a creamy brown.
