The Hard Tube Coco Worm, also known as the Hard Tube Feather Duster, Protula Tubeworm, or Hard Tubeworm, has a crown that can be white, yellow, orange, pink, or red. The radioles m ay be banded or patterned. Younger Hard Tube Coco Worms have bi-lobed crowns, while the crowns of older individuals are spiraled.The Hard Tube Coco Worm secretes a calcareous tube, approximately 1/2 inch in diameter and 5-8 inches long, to house its vulnerable worm body. When disturbed, it can quickly retract its crown and close its operculum to shut the top of its tube. It usually anchors its tube in a crevice of the rocky reef or in the gravel along current-swept reef slopes. It uses the radioles to filter out floating plankton. Show more
