The radioles on the crown may exhibit banding or patterns. Notably, younger Hard Tube Coco Worms have bi-lobed crowns, while older individuals boast spiraled crowns. To protect its delicate worm body, the Hard Tube Coco Worm secretes a calcareous tube, measuring about 1/2 inch in diameter and 5-8 inches in length. In response to disturbances, it can swiftly retract its crown and seal the top of the tube with an operculum. Typically, it anchors its tube in crevices on rocky reefs or in gravel along current-swept reef slopes. The worm utilizes its radioles to filter floating plankton for sustenance. Proper care f
