Summary
| Description |
English: Dorsal view of Coeloplana to illustrate the similarity between Ctenophora and Turbellaria. The branched intestine (G) is drawn on one side of the animal only; it opens to the exterior by means of a pharynx (not shown). The mouth is shown by the line surrounding the otolith (OT) in the centre. The mouth is ventral, the otolith dorsal. The two branched tentacles (TB) are seen partially extruded from their sheaths (TS); when fully extended they exceed the diameter of the animal five or six times. The short tentacles (T) are drawn on one side only. Coeloplana has been found in shallow water in the Red Sea and on the coast of Japan. Ctenophora possess two similar long branched tentacles, a ventral mouth and dorsal otolith. |
