Contains primarily marine invertebrate sausage-shaped organisms, that have lost their segmentation, found in sand and mud of tropical and subtropical seas. A flattened extension of the head is curved along its lateral edges and sometimes shaped like a scoop or spoon to form a nonretractable anterior proboscis. Some respiration probably takes place across the body wall, but the hind gut is often utilized as a respiratory organ by drawing water through the anus.  ]]></dc:description></metadata>
