Cardiovascular system
Bubble Tip anemone do not have a regular closed cardiovascular system, but have a large and single body cavity that works as this system and as a digestive system. In actuality, the Bubble Tip anemone is much like coral in that it uses a gastrovascular system in place of a cardiovascular system. tentacles are in turn responsible for picking up the foodstuff, while oxygen passes through their tissue. Bubble tip anemone can achieve their circulation through their symbiotic relationship with clownfish. The activity of clown fish stimulates the flow of oxygen rich water into the anemone, allowing it to gain this vital gas while also providing a protective area for the fish.
