| They have internal separations of body parts arranged in hexamerous cycles and usually with two ciliated oral cavities. |
| It may be desirable to separate generically the species having the hemispherical apertures, median ciliated pore, and sublateral avicularium. |
| The loss of ciliated epithelium emphasizes the need for hydration to improve the pulmonary toilet. |
| The mouth is surrounded by the ciliated feeding structure known as a lophophore. |
| These are trapped by the protrusible ciliated feeding tentacles, or lophophore. |
| Through this opening, the lophophore, a ring of ciliated tentacles centered on the mouth, protrudes to capture small food particles. |
