| The tubelike manubrium hangs from the centre of the bell, connecting the mouth at the lower end of the manubrium to the coelenteron within the bell. |
| Anthozoan polyps have an internal pharynx, or stomodaeum, connecting the mouth to the coelenteron. |
| In some colonies, polyps share a common coelenteron through which food captured by any member is distributed to others. |
| Because dissolved oxygen in the water column is continuous with water in the coelenteron, it may lead to increased oxygen concentration within the coral. |
| Water entering the coelenteron through the mouth leaves the body through the pores. |
| The mouth opens into a cavity, the coelenteron, or gastrovascular cavity, which is digestive and circulatory at the same time. |
