| Water entering the coelenteron through the mouth leaves the body through the pores. |
| In some colonies, polyps share a common coelenteron through which food captured by any member is distributed to others. |
| The mouth opens into a cavity, the coelenteron, or gastrovascular cavity, which is digestive and circulatory at the same time. |
| Anthozoan polyps have an internal pharynx, or stomodaeum, connecting the mouth to the coelenteron. |
| The mouth of a scyphomedusa of the order Rhizostomae is subdivided into thousands of minute pores that lead by tubes to the coelenteron. |
| The oral tentacles then pass the paralysed prey to the mouth and into the coelenteron for digestion. |
