Accessory feeding structures
Accessory feeding structures: Other structures such as palps, tentacles or a radiolar crown ("grooved palps"). There are forms of single pair of grooved palps nearly always attached dorsally or near the junction of the prostomium and peristomium, or multiple grooved palps sometimes forming a crown. Dorso lateral ciliated folds in the roof of the buccal cavity may be present in some polychaetes.
